Mawlid al-Nabi Dates by Year

Calculated Gregorian dates and weekdays for 12 Rabi al-Awwal, commonly associated with Mawlid al-Nabi. These are deterministic planning dates from the tabular Islamic calendar. The locally observed date can differ by about a day because a new Islamic month is established by moon sighting.

Planning date, not a religious ruling. Confirm the start of a religious observance with your local mosque or national authority.

How these dates are calculated

The calculator uses the tabular Islamic calendar, a fixed 30-year arithmetic cycle. It maps 12 Rabīʿ al-Awwal in each overlapping Hijri year to a Gregorian date through the Julian Day Number. That makes every calculation reproducible, including the uncommon Gregorian years containing two occurrences.

Observed Islamic dates are not set by arithmetic alone. Weather, location and the authority whose announcement a community follows can move the actual start by a day, occasionally two.
