How our dating works

HIJRI · CANONICAL

The date the sources actually record. Events are stored, indexed, and displayed by Hijri date — it is the truth of the record.

GREGORIAN · DERIVED

Computed for orientation and always shown beside the Hijri date with ≈. The early calendar ran on moon sighting, so conversions carry ±1 day of honest error. We convert with the tabular (arithmetic) calendar — leap years 2, 5, 8, 10, 13, 16, 19, 21, 24, 26, 29 of each 30-year cycle, civil epoch — and never mix methods; pre-1582 dates display in the Julian calendar as historians give them.

Precision

DayThe sources name the day. The event appears on its day page and anniversary.

MonthOnly the month is recorded. The event appears on every day of that month, below day-precise events, labelled.

YearOnly the year survives. Shown last and clearly labelled — never pinned to an invented day.

Why some days are blank

The classical chronicles fixed a day only when the event demanded it — treaties, battles, deaths of rulers. Most history was recorded by month or year. A blank day on Mawaqit means no source names that day. We would rather show you nothing than invent something.

Confidence
