No, the Muslim calendar does not use BC (Before Christ) as a reference for its years. Instead, it is based on the lunar cycle and counts years from the Hijra, which is the migration of the Prophet Muhammad from Mecca to Medina in 622 CE.
The Islamic calendar, also known as the Hijri calendar, has twelve months and is approximately 10 to 12 days shorter than the solar calendar used in the Gregorian system. Therefore, the Islamic year is not aligned with the BC/AD system, and it does not include the concept of BC.
Instead of BC, the Islamic calendar uses AH (Anno Hegirae), which stands for ‘in the year of the Hijra.’ This means that while individuals using the Gregorian calendar may reference years as BC and AD, the Muslim calendar solely counts years from the point of the Hijra onward.
