Hi Gerard
Calendars around the world follow a combination of solar and lunar cycles:
periodic mismatches between the two have given rise to different ways of
keeping track of the days.
India also has more than one system in regular use, although as Pranav
mentions, only one vernacular calendar is official.
It should be possible to devise algorithms that generate the equivalent
date corresponding to a different system, but they need to be, of course,
sensitive to the periodic 'corrections' inserted to synchronise with the
passing seasons. For the Gregorian calendar (with which you are familiar)
in use in most places, this adjustment is popularly thought of as only the
leap year, but there are other fine adjustments at longer intervals.
Hope this helps
Vickram

Hoi Harsh,
One obvious thing is to make sure that all the items used in Wikidata have
labels in the Gujarati language. This allows you to find them and to see
them wherever they are used.
I have started adding statements like this months follows / is followed by
that month.. Given that some articles list months from the same calendar,
this can only be right when all aspects of a month are exactly the same
(think number of days, the number it is given in the year etc). As I do not
know all this I have asked for help.
What would be useful to know is if a calendar is used on a specific
Wikipedia (and in a certain language). When other calendars are used, it
makes sense for dates to be visible in the calendars used in Wikipedias. I
assume that it is possible to convert to and from the "common" calendar.
I do know very little about calendars; I only use one. So when you/we find
that we cannot express facts about a calendar, we may need more properties
to express this.. Are there any ? I will gladly help in getting these
properties requested and created.
Finally, Wikipedia and by inference Wikidata is about the sum of all
knowledge. It makes sense for us to know about any and all calendars.
Thanks,
GerardM

Hoi,
I blogged about calendars. The problem I face is that I am adding
statements to the calendars in use in India.. I have worked on the Nepali
and the Bengali calendar and, I find that in the English Wikipedia some
months are merged into one article.
What I want to know is if these months exactly are at the same time or
not. Many calendars have special days. It would make sense to have an item
for them as well. I assume that many of the Indian Wikipedias have articles
for such events. It will help when they are known to be part of a specific
calendar..
Are there people who can help me with this ?
Thanks,
GerardM
