Baisakhi is held on the first day of the lunar month of Baisakh, which falls in the month of April. One of the main events of the day is the raising of a new Nishan Sahib, the Sikh flag. Baisakhi also marks the anniversary of the first initiations into the Khalsa, the special company of the faithful to which most adult Sikhs belong. Hence, the initiation rite called “taking amrit” frequently occurs on this day.
