Happy New Year to Indians

Thanks for your comment M-L. Indian calender unlike the Roman one does not solely base itself on the Solar cycle. The months are calculated basis the size of the month, since there are nearly 30 days in a Lunar cycle, so the months are roughly of 30 days, I say roughly as the Lunar cycle is not completely 30 days and the moon completes its cycle in less than 30 days so actually sometime is does happen that in a single 24 hours duration there are two separate Saka era or Vikram Sambat dates(like from 6:00 AM-3:00PM it is date 1 and from 3:00PM it becomes date 2) it is highly calculative and I am not very good in astronomy things. The year therefore is of around 354 days (as a few days are counted as two dates) which is 11 days lesser than the normal 365 days cycle of Solar Year However we do not actually forget the Sun and the Solar cycle. So every three years we have an extra month (known as Malmas), to account for the approximate 33 days we lost from the solar year while our calculation of Lunar months. So in the long run the averaged out year remains around 365 days (As we know the actual time to complete the revolution is more than 365 days so the approximation) I must say I am not sure if our ancestors were technologically advanced or not, but they certainly were great in astronomy

@shipreeta Indians who do business with the Western world, certainly use the Roman calendar, don't they?
