From 11:13 PM on March 24th to 12:27 AM on March 25th.
Holika Dahan has its roots in ancient Hindu mythology. Legend has it that there was a formidable demon king, Hiranyakashipu, who desired immortality.
He had a son named Prahlad who was a devotee of Lord Vishnu, much to the dismay of his father who wanted to be worshipped as a god.
Hiranyakashipu ordered his sister Holika, who was immune to fire, to sit in a fire with Prahlad on her lap to eliminate him.
With Lord Vishnu's grace, Prahlad remained unharmed while Holika was reduced to ashes, symbolizing the triumph of good over evil, celebrated during Holika Dahan.
As per Drik Panchang, the auspicious time for Holika Dahan starts at 11:13 PM on March 24 and ends at 12:27 AM on March 25.
