In another thread, I have also talked about how #TamilNewYear is calculated and it's astronomical significance.
This calendar lists major Hindu festivals celebrated in year 2022 with Gregorian & Tamil Hindu dates.

The #TamilNewYear which starts on Chitirai 1(Apr 14 2022) is called as 'சுபகிருது வருடம்' .
60 Year cycle is followed in Hindu calendar system, this corresponds to a Hindu century.

After completion of sixty years, the calendar starts a new with the first year 'பிரபவ'

60 year cycle is calculated based on 2 major planets Saturn (sani) which takes 30 years and Jupiter (Viyazhan) which takes 12 years respectively to complete 1 cycle around the Sun.

It takes 60 years for these planets to come to the same position.
Sat 30x2=60
Jup 12x5=60

FYI: Tamil months start and end based on the Sun's shift from one Rasi to the other, but the names of the months are based on the star on the start of Pournami in that month. The name of the month is some times the name of the star itself.

#TamilNewYear is celebrated on the 1st day of the Tamil Month Chithirai which falls on April 13th / 14th every year, this is based on precise astronomical calculation and events, when sun leaves Meena Rasi (Pisces) and enters the first zodiac sign Mesha Rasi (Aries).

Not only Tamilians, but several other cultures (non Abrahamic) around Asia celebrates April 14th + or - 1 day as their new year.

Tamil New Year calculation is not based on seasons / places, if we depend on these entities, we cannot get an accurate date & time, we need something that is fixed which can’t be altered even if we look after 1000’s of years.
