And today, how this festival takes place?
The date of Holi is decided by Hindu calendars, which usually follow the moon (although some are based on the sun), but it is principally celebrated in the month of Phalgun (February-March).
In 2017, the Indian government has stated that Holi were on Monday, March 13, which will be a national holiday. In the Indian towns of Barsana and Nandgaon, a local variation known as the Lathmar Holi celebration takes place several days before the actual Holi festival.
Celebrations begin the night before with Holika Dahan, which means Holika's Death. Bonfires are lit to burn an effigy representing the female demon Holika in a symbolic destruction of evil. Worshippers gather wood for the fire in the days before the event and build bonfires in parks and open spaces near temples. They also buy coloured powder, food and drinks for the celebrations. When the fire is lit, worshippers gather around it, singing, dancing and praying for any evil within themselves to be banished.
On the day of Holi itself, people chase each other and throw coloured powder, or spray coloured water. It seems to be the friendship and love event...
