Tabular ("Kuwaiti") Islamic calendar — deterministic arithmetic. Real month starts follow the moon sighting and can differ by ±1 day.
Islamic dates by year
Pick a Gregorian year to see every Islamic observance that falls within it — with the exact Gregorian date, weekday and Hijri date for each.
What Hijri Calendar does
- Two-way conversion — Gregorian → Hijri and Hijri → Gregorian, recomputed live as you type, with the weekday for every date.
- Exact, reversible math — the tabular ("Kuwaiti") algorithm maps each date through the Julian Day Number, so conversions round-trip perfectly 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 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 ("Kuwaiti") 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 conversion deterministic and reversible — the same input always gives the same output, and Gregorian↔Hijri round-trips exactly. 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.
When is Ramadan and Eid in 2026?
In 2026, 1 Ramaḍān falls on 18 February 2026 (Wednesday) by the tabular calendar, Eid al-Fiṭr on 20 March 2026 and Eid al-Aḍḥā on 27 May 2026. Open the 2026 page for the full list of Islamic dates, and remember the actual observance may shift by ±1 day with the moon sighting.
