Falgun or Phalgun (
Bengali: ফাল্গুন;
Nepali: फाल्गुण) or Phagun (
Assamese: ফাগুন) is the eleventh month of the year in the
Bengali calendar,[1] the
Assamese calendar,[2] and the
Nepali calendar.[3] In the revision of the Bengali calendar used in
Bangladesh since October 2019, the month has 29 days in
common years or 30 in
leap years of the
Gregorian calendar.[4] In the previous version of the calendar, used in Bangladesh from 1987 through October 2019, Falgun had 30 days in common years or 31 days in leap years.[5] The month has 29 or 30 days, based on the true movements of the Sun, in the old non-reformed Bengali calendar, still used in
West Bengal,[1] and in the Nepali calendar.[6]
Falgun was named for the nakshatra (
lunar mansion) Uttara phalguni, in the vicinity of which the full moon appears at that time of the year.[7] It marks the arrival of
spring, the sixth and final season in Bangladesh, West Bengal,
Assam, and
Nepal.[1] Falgun falls between mid-February and mid-March on the Gregorian calendar.[8]
