This is because the Tamil calendar year "averages" 365 days for a year. The
length of the months vary from 29 to 32 days. Also the same month can have
30 days in one year and 31 days in another year. A new month begins with
"sankranthi" (the sun entering a new zodiac sign), but the complication is
brought in because of the fact that if the sankaranthi occurs after sunset
(6 PM) the month starts the next day and an extra day is added to the
current month.
I was looking at the calendar on my wall - all the days are there and July 1st
is always Aani 17th. But in practice this is not so - from what you say and
from what I have understood. Therefore the printed tamil calendar can only be
accurate with a margin of error of two days. Right? - only the name of the
year can be more or less accurate - but even that, for the beginning and the
end of the year there is a two day margin of error?
