Lunisolar Cycles a multiple of the Gregorian 400-year CycleDear Helios, Victor and Calendar People Some time ago, I had worked out some lunisolar cycles that are a multiple of the Gregorian 400-year cycle. They are at http://www.the-light.com/cal/Lunisolar400.html of http://www.the-light.com/cal/kp_Lunisolar_xls.html . This list does not include the 5.7 million year cycle used for Easter, because it is so long. For relatively short cycles we have 13 Gregorian cycles with 280*235 – 15*99 = 64315 lunar months averaging 29.5306072 days 16 Gregorian cycles with 344*235 – 17*99 = 79157 lunar months averaging 29.5305785 days 29 Gregorian cycles with 624*235 – 32*99 = 143472 lunar months averaging 29.5305913 days 45 Gregorian cycles with 968*235 – 49*99 = 222629 lunar months averaging 29.5305868 days The cycle of 29 Gregorian cycles has exactly 8967 months per 725 years and the ratio 29/32 crops up. The cycle of 45 Gregorian cycles is very accurate to today’s mean synodic month and has a ratio of 45/49. The ratio of 29/32 or 45/49 is the number of Gregorian cycles per correction of the Metonic cycle by 1/19 month, which can be done by truncating on Metonic cycle by an Octaeteris of 8 years equated to 99 lunar months. For the Gregorian Lunisolar calendar the ratio is 750/817, which is about 0.918 and is equivalent to about one 1/19 month correction every 367.197 years. The cycle of 45 Gregorian cycles has about one such correction every 367.347 years and for the 29 Gregorian cycles, it is exactly one such correction every 362.5 years (half of 725 years).

Re: Mean Lunation & 399 Lunation RE: Lunisolar Cycles a multiple of the Gregorian 400-year CycleDear Brij and Calendar People Brij should find that 334 and 353 years MUCH closer to a whole
number of lunations. They are got by subtracting 8 years from a multiple of
19-year cycles, which achieves one 1/19 month correction of the 19-year cycle.
Brij quoted me out of context. The ratio I refer to is the number of 400-year
cycles per correction of the 19-year cycle. 399 years is equal to 21 nineteen-year cycles and so is about 2
days short of a whole number of lunations. Brij’s other approximations
are also poor and tolerate an error up to 3 days. A good approximation will be of the form of 19*M – 8*T
years approximated to 235*M – 99*T lunations, where M and T are integers
and the ratio M/T is around 17 or 18. The quantity T is the number of corrections of the 19-year cycle
as I have described. The ratio I referred in the quote is equal to Years/(400*T)
and the number of years per correction is simple Years/T. Brij’s better approximations have M/T as follows 220 years = 12*19 – 8 , so M=12, T=1, therefore M/T=12 850 years = 46*10 – 3*8, so M=46, T=3, therefore M/T =
15.3333 In both cases M/T is a little too small. Also 896 years = 48*19 – 2*8, so M=48, T=2, therefore M/T = 24 In this case M/T is a little too large. These are not complete lunisolar cycles, because they do not
have a whole number of days. For complete lunisolar cycles, go to http://www.the-light.com/cal/kp_Lunisolar_xls.html

Re: 5*47 lunation RE: Mean Lunation & 399 Lunation RE: Lunisolar Cycles a multiple of the Gregorian 400-year CycleDear Brij and Calendar People The correction of the 19-year cycle by removing 1/19 of a lunar
month can be realised in a calendar by removing 8 years of 99 lunar
months, leaving a truncated Metonic cycle of 11 years of 136 months. This can be
seen that if it were done 19 times to 19 Metonic cycles; you’d then get 19*11=209
years of 19*136=2584 lunar months. This is the same number of years and one
month less than 11 Metonic cycles of 209 years of 11*235=2585 months. Brij has not shown how a correction by the omission of ONE tithi
(in about 219 years) could be realised . Such a correction could be
realised through epacts, as is done by the Easter Computus. Also, correction by 1/19 lunar month has an advantage over any
other fraction of a lunar month such as 2/59 or 1/30 lunar month is that once
can construct a cycle with a whole number of years and whole number of lunar
months with just one or any whole number of these corrections. In any cycle of
a whole number of years and a whole number of lunar months the total correction
of the Metonic cycle in lunar months must be a whole number of 1/19
lunar months. One can work out the number of Metonic Cycles M and the number
of truncated Metonic cycles T, for any cycle of Y years and L lunar months: M = 99*Y – 8*L T = 235*Y – 19*L There is no such formula for the number of tithi corrections
that gives whole numbers for any pair of Y and L. That is why M and T are so
important and cannot be ignored. For an accurate cycle M/T must be near 17
to 18. In my cycles of a multiple of 293 and 128 years I didn’t
say how many lunar months there are in any of the cycles, but I did give T the
number of truncations. The number L of lunar months for a cycle of Y years with T
truncations can be worked out as L = (235/19)*Y – T/19 For example, seven 128-year cycles with two truncations gives (235/19)*896 – 2/19 = (210560/19) – (2/19) =
210558/19 = 11082. Brij’s posts are not totally meaningless,
but he fails to demonstrate that his ideas have value or are even worth
thinking about. He shows a lack of judgement over the accuracy and precision of
his figures and gives the impression that he has thought very little about his
ideas and has just done some calculations. He does no favours by presenting us with inaccurate cycles and
then saying somehow they’ll be corrected. Accurate cycles are available. Karl 10(14(19 From: East Carolina University Calendar

Re: 7 omissions RE: 5*47 lunation RE: Mean Lunation & 399 Lunation RE: Lunisolar Cycles a multiple of the Gregorian 400-year CycleDear Brij and Calendar People From: East Carolina University Calendar
discussion List [mailto:CALNDR-L@...] On Behalf Of Brij
Bhushan Vij Karl,
sir: 2675th 5350th
8025th
10700th
13375th
16050th 18725th
lunation. to arrive at days vs
tithi alignment. KARL SAYS: A correction of the 19-year cycle requires a
change in the years vs. tithi alignment. A change in the days vs. tithi
alignment won’t correct the 19-year cycle without a change in the year
vs. tithi alignment. The Gregorian Easter Computus corrects the 19-year cycle
by changing the number of tithis in a year. There is no count of days in
the Easter Computus. Brij’s suggestion seems to say that every 2675th
lunation has 28.5 tithis rather than the usual 29.5 tithis. This tells me
nothing about how the 19-year cycle would be corrected, because there is no
mention of the year. However I guess that what Brij was aiming at is that every
lunation has 29.5 tithis without exception and that any year that has
the specified lunation has one tithi removed from it, so bringing the mean
number of lunations per 19 years down from 235 to a more accurate value near 234.997.
Like the Easter Computus, this changes the number of tithis in a year. As far as I know, Hindu calendars do not use the 19-year cycle
or any correction of it, but instead reckon the years and lunations independently.
Hence referring to them is not relevant to correcting the 19-year cycle. I notice that the number of tithis in 2675 lunations is
78912.5. Brij’s calculation seems to be about 10 tithis short of
this. Also the 525313rd tithi is completely wrong. My submission of
adding THREE(3) tithi during 1730-year cycle is in this link that get
automatically adjusted by the omitted lunation over (9*1730)
=15570-years. I agree with 'A
good approximation will be of the form of 19*M – 8*T years approximated
to 235*M – 99*T lunation, where M and T are integers and the ratio
M/T is around 17 or 18' and leave these for evaluation and ....Accurate
cycles are available, but newer cycles need be examined & found. KARL SAKS: Why? M = 99*Y – 8*L T = 235*Y – 19*L (i) for Y=1730 &
L=21397; M= (99*1730) –
(8*21397) =94; T = (235*1730) – (19*21397) =7;
M/T =94/7 = 13.428571428571…1 and (ii) for Y=15570 &
L=192574 M-2= [(99*15570)
– (8*192574) =838 & T-2=[(235*15570) – (19*192574)
=44; M/T =838/44 = 19.0454..455 These results do not
fall in the range. KARL SAYS I made an error in specifying the range of M/T. I
meant around 18 or 19 rather than 17 to 18, so (ii) is accurate. 15570/T = 353.863, which puts it close to the 353-year
cycle. >He does no favours by presenting us with inaccurate cycles
and then saying somehow they’ll be corrected. KARL DISAGREES: Plenty of work has been done on lunisolar cycles
on this list and Brij seems to ignore it. See http://www.the-light.com/cal/kp_Lunisolar_xls.html
which forms just part of this work.
KARL REPLIES: I think it is due to lack of ability to think
about the subject rather than education. Karl 10(14(22

Re: CLARIFYING RE: 7 omissions RE: 5*47 lunation RE: Mean Lunation & 399 Lunation RE:Dear Brij and Calendar people I think Brij has made a few errors: He said that correction would occur at 78902nd
157803rd
236706th
315607th
394509th
473411th
525313th 'tithi',
from 2675th
5350th
8025th
10700th
13375th
16050th
18725th lunation. but these tithis do not all occur in their respective lunations.
In particular the last one is wrong. With exactly 29.5 tithis in a
lunation, I make it 78902nd
157803rd
236706th
315607th
394509th
473411th
525313th 'tithi',
from 2675th
5350th
8024th
10699th
13374th 16048th
17808th lunation.
This can be seen by dividing the tithi number by 29.5 and rounding
up. I think Brij intended the 7th set of figures to be 552313th and 18725th which should be 18723rd . I could not see any connection between the above example and the
1730-year cycle, but given that the 1730 years have 631214.5 tithis, it became
evident that EIGHT corrections are done every 1730 years (one every 216.25
years). This suggests: 78902nd
157803rd
236706th
315607th
394509th
473411th
552313th 'tithi',
from 865th
1730th
2595th
3460th
4325th
5190th
6055th quarter year Brij mentions a different idea of the Harappan year of 364
tithis. I’ve mentioned in an earlier E-mail that a tropical year has
about 365.2422*(29.5/29.53059)=364.864 tithis. The 19-year cycle of 235*29.5=6932.5 tithis gives 364.868421…
tithis, which is exactly 364 33/38 tithis to a mean year. If one tithi
were removed from a year once every 219 years, this would be reduced to 364.863855
tithis which is quite accurate. One can’t fault Brij on his choice of 219
years given for a mean year very close to 365.2422 days. According to the 19-year cycle, 1730 years would have 1730*(364
33/38) = 631222 7/19 tithis. Take 8 from this and you get 631214 7/19 tithis,
which is quite close but not exactly the same the 631214.5 tithis reckoned by
Brij. It is in fact 5/38 tithis short. Perhaps, the eighth correction (not shown)
is by 33/38 tithi instead of 1 tithi, thereby creating one year of exactly 364
tithis. There is a simple relationship between the number of truncations
T of the 19-year cycle and the number of X of these tithi corrections. T = (59/38)*X X = (38/59)*T This is because 59 tithi corrections correct by two lunar months
so does 38 truncations. Brij’s 15570-year cycle with T=44 would require 44*59/38=
68 6/19 of these tithi corrections and so cannot be realized by them, because a
whole number of them is required. Also Brij mentioned the idea of making a lunar calendar
identical to a solar calendar but with the 13th day omitted from
each month. This I have pointed out would make either the lunar month too short
or the solar year too long. I showed him that if the 13th were kept
in every 13th lunar month and every intercalary month (not corresponding
to a solar month) had 31 days less any omitted 13th, then a 391-year
cycle of 4836 lunar months would result, which is considerably more accurate
than the 19-year cycle. It has M=21 and T=1. Alternatively, one could have one
13th in a lunar month annually except in a year with a saltus lunae. Contrary to claims by Brij such an idea does not use tithis of

18725th lunation. to arrive at days vs tithi alignment. KARL SAYS: A correction of the 19-year cycle requires a
change in the years vs. tithi alignment. A change in the days vs. tithi
alignment won’t correct the 19-year cycle without a change in the year
vs. tithi alignment. The Gregorian Easter Computus corrects the 19-year cycle
by changing the number of tithis in a year. There is no count of days in
the Easter Computus. Brij’s suggestion seems to say that every 2675th
lunation has 28.5 tithis rather than the usual 29.5 tithis. This tells me
nothing about how the 19-year cycle would be corrected, because there is no
mention of the year. However I guess that what Brij was aiming at is that every
lunation has 29.5 tithis without exception and that any year that has
the specified lunation has one tithi removed from it, so bringing the mean
number of lunations per 19 years down from 235 to a more accurate value near
234.997. Like the Easter Computus, this changes the number of tithis in a year. As far as I know, Hindu calendars do not use the 19-year cycle
or any correction of it, but instead reckon the years and lunations
independently. Hence referring to them is not relevant to correcting the
19-year cycle. I notice that the number of tithis in 2675 lunations is
78912.5. Brij’s calculation seems to be about 10 tithis short of
this. Also the 525313rd tithi is completely wrong. My submission of adding THREE(3) tithi during 1730-year cycle is
in this link that get automatically adjusted by the omitted lunation over
(9*1730) =15570-years. I agree with 'A good

meant around 18 or 19 rather than 17 to 18, so (ii) is accurate. 15570/T = 353.863, which puts it close to the 353-year

A Possible: 5*47 lunation CalendarDear Brij and Calendar People Brij said Use of Tithi value in Hindu astronomy is well known,
for long – especially in Panchang calculations! However,
use of (5*47) lunation per 19-years had never been in vogue. A vision of a possible 5*47 lunation calendar that may possibly
been used by the Harappan people has come to me. (1)
Each year has exactly 365 dates and is divided into five seasons
of 73 dates. (2)
Months alternate between 30 and 29 dates for 47 months equal to
19 seasons, so that the 1st and 47th month have 30 dates. (3)
Occasionally there will be a dateless day not counted in a year
or month in which a special festival is celebrated, such dates occur once every
20 seasons and 20 dates = 1480 dates = 1481 days for a mean month of 29.5305779…
days. This also gives rise to a mean year of 365.2466216… days
and follows the 19-year cycle. This mean year could be corrected by taking one date from a year
about once every 225 years or so. This would cause the months to run a day
later with respect to the year and seasons. The dateless dates could
still run once every 20 seasons and 20 days to make the mean month slightly longer. This calendar does not use a tithi of 2/59 lunation (or 1/30
lunation), but a tithi of 47/1387 lunation normally equated to 1/365 year. Each
date counts one of these tithis. Karl 10(14(23 From: East Carolina University Calendar

Brij's 1730=(91*19)+1 RE: Astronomers' Insight RE:Dear Brij and Calendar People From: East Carolina University Calendar
discussion List [mailto:CALNDR-L@...] On Behalf Of Brij
Bhushan Vij
Distribution of
1730-years in grouping of 19-years, also is possible as: [1730=(91*19)+1
and (86*19+12*8)], where each 19-years/5*47 i.e. 235 lunation, may have
suggested corrections. KARL SAYS: This is no
value whatsoever! Only Y=(M-T)*19 + T*11 is of value and then only
if M/T is not far from 18 or 19, where M and T are as defined in an earlier note and calculated
by Brij. Each 11 has 136 lunar months and corrects the 19
with 235 lunar months. The total number of lunar months L = 235*M – 99*T. Brij calculated: M = 99*Y – 8*L T = 235*Y – 19*L (i) for Y=1730 &
L=21397; M= (99*1730) –
(8*21397) =94; T = (235*1730) – (19*21397) =7;
M/T =94/7 = 13.428571428571…1 and (ii) for Y=15570 & L=192574 M-2= [(99*15570)
– (8*192574) =838 & T-2=[(235*15570) – (19*192574)
=44; M/T =838/44 = 19.0454..455 This gives rise to the following examples: 1730=(87*19+7*11) with M/T = 94/7 = 13 3/7 which
is too small 15,570=(794*19+44*11) = 2*(397*19+22*11)
with M/T = 419/22 = 19 1/22 which is close. Brij may note that M-T = 11*L – 136*Y Karl 10(14(24 PS: if you take 8 years to have 99 lunations, then 1730=(86*19+12*8) has
21398 lunations rather than 21397 from 1730=(87*19+7*11) . --

- Tithi.
It may be seen that NO TITHI is removed and ALL *lunar months
have the same number of 29.5 Tithi*. It is thus, CORRECTION (alignment) and not
removal, I submitted. KARL SAYS: All I’ll say here that some of the listed
tithis do not occur in the respective lunations. This leads to contradiction.
KARL SAYS: I don’t see how adding three tithis can change
631868.9881… days to 631868.60829… days.
KARL SAYS: I am aware that 1730 years have about 21,397.1
lunations. Hence 21,397 lunar months is about 3 tithis short of 1730 years. I see that Brij has made nine of these 1730-year cycles into a
more accurate cycle by adding one lunar month to nine periods of 21,397 lunar
months to get 192,574 lunar months in 15,570 years. If there are 631214.5 tithis in each of the first eight
1730-year cycles, then the ninth must have 631217 tithis to get the required 192,574
lunations in the 15,570-year cycle. If the 15,570-year cycle were made by whole tithi corrections of
the 19-year cycle, we’d require 1298 corrections (= 44 lunations) over nineteen
15,570-year cycles, which is about one correction per 227.9 years (Yes, that 44
is the value of T). I’ll point out to calendar people that in an earlier
E-mail that Brij’s preference for the 1730-year cycle arises from the
fact that it is the sum of the 896-year cycle with 159 leap weeks and the
834-year cycle with 148 leap weeks so has 307 leap weeks. This gives it 52*1730+307=90,267
weeks equal to 631,869 days as reckoned by Brij above. This gives mean year of about 365.24219653 days and nine of
these with 192,574 lunar months have a mean lunar month of 29.5305753 days (29d
12h 44m 1.70241s).
KARL SAYS: So Brij has made the error of multiplying after
rounding, thereby multiplying the rounding error! What I did was to divide the tithi number by 29.5 then round up
(as appropriate for ordinal numbers).
KARL SAYS: Such a calendar can be made into a lunisolar calendar
based on the 19-year cycle (with corrections) only if leap days rather than
leap weeks are used. Then it could be done in a manner similar to the Gregorian
Easter Computus. It CANNOT be done with a leap week calendar, because 19 years would
in such a calendar contain exactly 991, 992 or 933 weeks which is 6937, 6944 or
6951 days, while 235 lunar months have either 6939 or 6940 days. However one could make a leap week calendar lunisolar by overlaying
a lunar calendar (which may count tithis) or using epacts that depend on which
year has a leap week, but neither would follow a 19-year cycle (with
corrections). Karl 10(17(24 --

Re: P.S. RE: Brij's 1730=(91*19)+1 RE: Astronomers' Insight RE:Dear Calendar People Brij’s check gives insight in why he publishes valueless
results such as 1730=(91*19)+1 or 1730=(86*19+12*8). From: East Carolina University Calendar
discussion List [mailto:CALNDR-L@...] On Behalf Of Brij
Bhushan Vij Karl,
sir: [A] (86*19)+(12*8)-yrs
=20209.747315242312 lunation) + (1187.353575436513 lunation) =
21397.100890678825 lunation; and [B] (87*19)+(7*11)-years =(20444.744377047455 lunation)+( 952.3565136313696
lunation =(21397.1008906788245 lunation). I
was only checking if "1730=(86*19+12*8) has
21398 lunations" were indeed so? Please note I wrote if you take 8 years to have
99 lunations and also took 19 to have 235 lunations. See calculation further
below. Actually, the check Brij did would give the same result
(allowing for calculator error) for both [A] and [B] regardless of what number
of lunations per year you use. One could use as 12, 12.4, 13.75
lunations per year or even the trivial value of 1 lunation per year and still
get [A] and [B] equal . It tells you nothing more than
(86*19)+(12*8)=(87*19)+(7*11). This arises form the fact that multiplication is distributive
with respect to addition; i.e. a(b+c) = ab+ac. Brij’s lack of awareness of this may explain why he
publishes such valueless calculations. A more valuable calculation would be to have a whole number of
lunations (lunar months) in each 19, 11 or 8 (e.g. 235, 136 and 99
respectively) as could be used in a calendar. Then we’d have: [A] 1730
years=(86*19)+(12*8)years = (86*235months=20210months)+(12*99months=1188months)
= 21398 months; and [B] 1730
years=(87*19)+(7*11)years = (87*235months=20445months)+(7*136months=952months)
= 21397 months. This statement tells you something about possible calendars. It
shows that if you want 21937 months in 1730 years you use (87*19)+(7*11)-years
rather than (86*19)+(12*8)-years. It also shows that when dividing a lunisolar
cycle into parts you need to check the months as well as the years and these
need to be calendar months and years (not astronomical years and months). Brij needs to note that this list is about calendars
rather than astronomy and therefore it is calendar years and months that
are of primary interest. Astronomical years and lunations are of interest only
in assessing or ensuring accuracy or and they are not fixed constants as Brij
assumes. Karl 10(14(25 --
