Here is your short paragraph on Tamil new year day:
This day falls on the first of Chittirai (middle of April) in accordance with the solar system (Soura month) is the day when the Sun enters “the sign Aries of the Zodiac”.
The day is considered to be a sacred occasion called Chittirai Vishu Punyakalam, available in the almanac. In the evening, the priest reads the pancagam (the new almanac).
In earlier days, being a hot season, arrangements were made to offer people with cool drinks and fans. The custom of partaking morgosa flowers mixed with sugar found a place in the feast on the day. The day is also called ‘Yugadi’. This was the day when Rama entered Ayodhya after winning the battle with Ravana.
