The 12th of Rabiʿ al-awwal is widely kept as the Prophet’s birthday. Some communities recite poetry and feed neighbours; others treat it as any other day. Either way, the point is his character — not a cake.
In Turkey, Mawlid an-Nabi in 2027 is expected on Saturday, 14 August 2027 (12 Rabiʿ al-awwal 1449). This uses the Umm al-Qura calculation. Moon sighting can shift a day — follow Diyanet and your local mosque.
The Islamic calendar (Hijri, Arabic lunar calendar) follows the moon; the Gregorian year follows the sun. It starts from the Hijrah. A month opens when the new crescent is sighted. Dates on this 2027 grid are estimates — moon sighting can move a day.
Twelve months, about 354–355 days: Muharram, Safar, Rabiʿ al-awwal, Rabiʿ al-thani, Jumada al-ula, Jumada al-akhirah, Rajab, Shaʿban, Ramadan, Shawwal, Dhul-Qaʿdah, Dhul-Hijjah. Namaz Buddy puts Gregorian and Hijri on the same cell. The converter uses that engine.
Four months are sacred: Dhul-Qaʿdah, Dhul-Hijjah and Muharram in a row, then Rajab. They are named in Bukhari (3197). The old rule was to halt war; today they are still marked for worship and travel.
2027 Ramadan, Eid al-Fitr, Eid al-Adha and the sacred nights have Turkey pages here. Calculation is Umm al-Qura. Diyanet and your mosque confirm the hilal. Adhan and fasting streaks live in the Namaz Buddy app.
