Muslim calendar (also known as Moslem calendar, Arabic calendar, Islamic calendar or Hijri calendar) is calendar used in many Muslim countries of Asia like Iraq, Egypt, Syria etc. This calendar used primarily for religious purposes, but often you can see these dates on coins or banknotes.
In general, there are several differences to our well known Gregorian calendar:
If you want to convert Muslim date to Gregorian date, you need to multiply original year by 0.97 and add 622:
YearGregorian ≈ YearMuslim × 0.97 + 622.
If you want to convert Gregorian date to Muslim date, you need to subtract 622 from original year and after multiply by 1.03:
YearMuslim ≈ (YearGregorian– 622) × 1.03.
5 piastres (Egypt, 1972) with both Muslim and Gregorian dates.
As mentioned before, described formulas are very rough, so this way is inadmissible for precise calculations. Moreover Muslim year does not start on 1st of January, so 2008 year corresponds to 1428-1429 years of Islamic calendar.
