PDF Islamic New Year 2020 1441-1442 AH
The Islamic calendar (or Hijri calendar) is a purely lunar calendar. It contains 12 months that are based on the motion of the moon, and because 12 synodic months is only 12 x 29.53=354.36 days, the Islamic calendar is consistently shorter than a tropical year, and therefore it shifts with respect to the Christian calendar.
The Islamic calendar is the official calendar in countries around the Gulf, especially Saudi Arabia. But other Muslim countries use the Gregorian calendar for civil purposes and only turn to the Islamic calendar for religious purposes. https://en.wikipedia.org/wiki/Islamic_calendar
The Islamic calendar employs the Hijri era whose epoch was established as the Islamic New Year of 622. The current Islamic year is 1441 AH. In the Gregorian calendar, 1441 AH runs from approximately 1 September 2019 to 20 August 2020.
