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?
