Here are the biggest festivals in Sri Lanka, which you must know about:
1. Sinhala and Tamil New Year

Marking the end of the harvest season, Sri Lanka celebrates its new year also known as Aluth Avurudda. The people in Sri Lanka think that the Prince of Peace, Indradeva, comes down to earth to bless the people with happiness and peace; thus, this is also the time for a change of thoughts. Both Sinhalese, as well as the Tamil people in the country have their rituals, such as the playing of a Raban, a drum, by women in the community, preparing Kiribath ( a rice preparation in milk), Kavum (an oil cake) and Kokis (a sweetmeat snack). The date of the auspicious new year gains its significance through astrological calculations.
This festival generally happens mid-April when the entire country is brought together in a festive spirit.
