IVY MIKE CALENDAR

In previous post, I have favored a 17-fold-division calendar. Now I have the equations that do the job. The Ivy Mike calendar is based on the 33-year cycle. It's very simple.
-------------------------------------------------------------------------------
Here are the formulas;
C = JD - 2434315.5
T = FLOOR[ ( 33*C + 692 ) / 709 ]
D = C - 21*( T - 1 ) - FLOOR[ 16*T / 33 ]
Where JD = Julian date, C = Day Count, T = Term or 17th-of-year, D = day-of-term

I use Mayan ( Haab ) names for convenience. The similarity to the Haab is in name only. There is the ommision of "Uo" and "Uayeb" from a Haab set of 19 names.

01) Pop ( 9th = Autumn Mid-quarter* )
02) Zip
03) Zotz ( 9th = Winter Solstice )
04) Tzec
05) Xul ( 9th = Winter Mid-quarter )
06) Yaxkin
07) Mol ( 13th = Spring Equinox )
08) Chen
09) Yax ( 16th = Spring Mid-quarter )
10) Zac
11) Ceh ( 19th Summer Solstice )
12) Mac
13) Kankin
14) Muan ( 1st = Summer Mid-quarter )
15) Pax
16) Kayab ( 6th = Autumn Equinox )
17) Cumku

*Mid-quarters are based on a solar declination = ( + or - ) 16.694°

Here are 17 "solar glyphs" I am fond of.

So let's input JD = 2455008.5 ( JUN 26, 2009 )
C = 20693
T = 964
D = 3
