About the Islamic calendar
Because the Hijri year is about 11 days shorter than the solar year, Islamic dates move earlier through the Gregorian seasons over time. This converter uses the widely adopted tabular calendar, which is ideal for planning and reference. For the precise start of religious months, always check local moon-sighting announcements.
Frequently asked questions
- What is the Hijri calendar?
- The Hijri (Islamic) calendar is a lunar calendar of 12 months in a year of 354 or 355 days. Its years are counted from the Hijra — the migration of the Prophet Muhammad from Mecca to Medina in 622 CE — and are marked AH (Anno Hegirae).
- Why might the date differ by a day from official dates?
- This converter uses the tabular (arithmetic) Islamic calendar, which follows a fixed mathematical rule. Religious observances such as the start of Ramadan are often based on the actual sighting of the crescent moon, which can differ by a day from the calculated date and can vary by country.
- What does AH mean?
- AH stands for Anno Hegirae, 'in the year of the Hijra'. It is the era used for Islamic calendar years, just as AD/CE is used for the Gregorian calendar.
