Questions

The Tamil rule from Sewell and Dikshit’s The Indian Calendar (1896), with Warren’s Kala Sankalita (1825).

When is Tamil New Year?

For every city, reckoned at Chennai: Wednesday, 14 April 2027, Friday, 14 April 2028 and Saturday, 14 April 2029. The Indian Calendar, Art. 28, p. 12

How is the date fixed?

By the Tamil rule for the solar months: when the Sun enters sidereal Mesha between sunrise and sunset, the month of Chithirai begins that day, and when it enters after sunset or before dawn, at the next sunrise. Tamil New Year is the first day of Chithirai, reckoned at Chennai for every city. The Indian Calendar, Art. 28, p. 12

Is Puthandu the same as Vishu?

They begin with the same entry of the Sun into Mesha but follow different rules, so their days can differ. Tamil New Year is Chithirai 1 by the Tamil rule at Chennai; Vishu is the first sunrise after the ingress, as kept in Kerala, which is popular practice. In 2027 Tamil New Year falls on Wednesday, 14 April and Vishu on Thursday, 15 April. The Indian Calendar, Art. 28, p. 12

Is the date the same outside Tamil Nadu?

Yes. The day is reckoned at Chennai and holds for every city, in India and abroad.
