Calendar and Holidays. Until the 13th of March, 1998, the Sikhs used a Hindu lunar calendar to determine their feast days. They now use their own Nanakshahi calendar which started on 14 March 1999 Gregorian (1 Chet 531 Nanakshahi ) and aligns with the Gregorian calendar, although it does not completely follow it.
