What is the Indian calendar?

The national calendar that is based on the Saka Era with Chaitra as its first month or normal year of 365 days was adopted in 1957 in accordance with the Georgian one.

However, the traditional Hindu calendar is known for its intricacies in describing events. It uses a somewhat multidimensional method to structure time and combines information about lunar days, months and then combines the same to the lunar months, solar months and movements of the Sun and moon. This system makes the Hindu calendar quite complex than the Western one that is only based on the two ideal units of time i.e. solar days and years.
