Dear Calendar People
I just updated the Bahai Leap Month cycles spreadsheet, now it includes
worksheets "Fast Grouping" and a "Slow Grouping" which show the leap
year grouping patterns for the cycles shorter than 1000 years. It is
now increased to 108 KB. Once again, its URL is:

The column label "DayEquiv" is a bit obscure. It is the numerator for
the fraction of a day in excess of 365 days that would apply if the
cycle was a leap day calendar. The denominator is the number of years
in the cycle. For example, for the 869-year cycle (picking a cycle at
random), its "DayEquiv"=210, which means its mean year length =
365+210/869 days, and a leap day calendar having 210 leap years in 869
years would have an exactly equal calendar mean year length.
