This date is set by the Islamic lunar calendar, not the Gregorian one. Rabi al-Awwal is the third month of the twelve Hijri months, and each Hijri month runs 29 or 30 days, beginning with the birth of the new moon. Twelve lunar months make a year of 354 or 355 days — about 11 days shorter than the Gregorian year — so the same Islamic date lands about 11 days earlier each Gregorian year.
The Gregorian date shown is the Umm al-Qura calculation: the official Islamic calendar of Saudi Arabia, built from astronomical calculation of the new moon, and the calendar this site's Hijri calendar converter uses. Other communities wait for the new crescent to be seen with the eye, or follow a different country's announcement — so the day your community actually observes can sit a day either side of the estimate. Because the Islamic day begins at sunset, the date begins the evening before the Gregorian day shown.
The marking date is fixed in the Hijri calendar at 12 Rabi al-Awwal, and scholars give different views on the day of the Prophet's ﷺ birth. For 1449, with 1 Rabi al-Awwal expected on Tuesday 3 August 2027, the 12th falls on Saturday 14 August 2027. Communities that begin the month a day later keep 12 Rabi al-Awwal but observe it on Sunday 15 August instead.
The same Hijri date, three cycles running. The Hijri year is about 11 days shorter than the Gregorian year, so each cycle lands earlier in the Gregorian calendar.
