Baisakhi, the harvest festival, falls on April 13. Celebrated in Punjab and Haryana,
this festival also commemorates the formation of the order of the Khalsa.
The birth anniversary of each of the ten gurus of the Khalsa Pantha is celebrated
as Gurpurab. Of the ten Gurpurabs occurring in a year, the most important is the
one that commemorates the birth of Guru Nanak.
Celebrated by the Sikhs one day after Holi, Holla Mohalla is observed in Anandpur
Sahiband Muktsar in Punjab. Prayers and contests in martial skills form an integral
part of the festivities.
