What Hijri Calendar does
- Two-way conversion — Gregorian → Hijri and Hijri → Gregorian, recomputed live as you type, with the weekday for every date.
- Deterministic, reversible math — the tabular civil algorithm maps each date through the Julian Day Number, so conversions round-trip within the arithmetic model across more than a thousand years.
- Key Islamic dates for any year — Islamic New Year (1 Muḥarram), Ashura, Mawlid al-Nabī, Isrāʾ and Miʿrāj, mid-Shaʿbān, Ramaḍān, Laylat al-Qadr, Eid al-Fiṭr, the Day of ʿArafah and Eid al-Aḍḥā.
- Honest about the moon — arithmetic dates are flagged as ±1 day from the actual sighting, never presented as a religious ruling.
FAQ
What is today’s Hijri date?
The converter above calculates today’s tabular Hijri date from your device’s local date when the page loads. Because observed Islamic months depend on local moon sighting, the religious date may differ by about one day.
How do Gregorian and Hijri years overlap?
A Gregorian year usually spans parts of two Hijri years because the lunar year is about eleven days shorter. Select a Gregorian year below to see its Islamic dates and observances.
What is the Hijri (Islamic) calendar?
The Hijri calendar is a lunar calendar of twelve months and 354 or 355 days, counted from the Prophet Muhammad's migration (Hijrah) to Medina in 622 CE — hence "AH", anno Hegirae. Because it is about eleven days shorter than the Gregorian year, Islamic dates move earlier through the seasons each year. Hijri Calendar converts any date between the two systems instantly, in both directions.
How does this converter calculate dates?
It uses the tabular civil Islamic calendar: a fixed arithmetic rule where a 30-year cycle contains eleven leap years and every date maps to a unique Julian Day Number. That makes the calculation deterministic and reversible — the same input always gives the same arithmetic output, and Gregorian↔Hijri round-trips exactly within this model. No lookup tables, no network, no dependencies.
Why can the date be off by a day?
Traditional Islamic months begin when the new crescent moon is actually sighted, which depends on weather and location, so the observed start can fall a day (occasionally two) before or after the arithmetic prediction. The tabular calendar is ideal for planning and historical conversion, but for the exact start of Ramadan, Eid or any religious observance you should follow your local mosque or national authority.
Where can I find Ramadan and Eid dates by year?
