The Hijri calendar also called the Islamic calendar is a lunar calendar consisting of 12 months in a year of 354 or 355 days. It originated with the migration (Hijra) of the Prophet Muhammad ﷺ from Mecca to Medina in 622 CE, which marks year 1 AH (Anno Hegirae). Because a lunar year is roughly 11 days shorter than a solar year, Islamic events like Ramadan and Eid advance through the Gregorian calendar each year. The Hijri calendar is the official calendar of Saudi Arabia and is used across the Muslim world to determine religious observances, holidays, and financial dates. Converting a Hijri date to Gregorian is essential for aligning Islamic dates with international timelines used in business and official documentation.
The Umm Al-Qura calendar is Saudi Arabia's official Islamic calendar, published by the King Abdulaziz City for Science and Technology (KACST). Unlike purely astronomical Hijri calendars, Umm Al-Qura is based on predicted crescent moon visibility using defined astronomical criteria rather than actual sighting. It is used for government administration, payroll, legal documents, religious scheduling, and business transactions throughout the Kingdom. The Umm Al-Qura calendar is typically planned years in advance, giving it predictability for official purposes. When using any Hijri to Gregorian converter, results may differ from the Umm Al-Qura calendar by up to one day in certain months, since the physical moon sighting can vary from the calculated prediction. Always cross-reference with KACST publications for official Saudi documents.
To convert your Gregorian birth date to Hijri, click the "Gregorian to Hijri" tab in the converter above. Enter your birth day, month, and year in the Gregorian (CE) calendar, then click "Convert Gregorian to Hijri." The result will show your full Islamic birth date including the Hijri day, month name (e.g., Rajab), and year (AH). This conversion is required for Saudi national identity cards (Iqama), passports, university enrollment, and civil registration records. If your birth date falls near a new Hijri month, note that the Umm Al-Qura calendar may place it one day differently from the astronomical calculation. For legal documents, always verify against your official Saudi Civil Status Commission records. Use the dedicated birth date to Hijri converter for additional formatting options.
To see today's Hijri date, click "Use today's Hijri date" in the converter above. The tool automatically reads your device's current date, converts it to the corresponding Hijri date using the astronomical calculation algorithm, and fills in the day, month, and year fields for you. You can then convert today's Hijri date to Gregorian with one click to confirm the result. The Hijri date advances roughly every 29 or 30 days per month (alternating, based on the lunar cycle), making the exact day depend on the month.

The Hijri calendar runs on a 12-month lunar cycle with alternating months of 29 and 30 days, giving a year of 354 days — approximately 11 days shorter than the 365-day Gregorian solar year. To convert a Hijri date to Gregorian, the converter calculates the total number of days elapsed since the Islamic epoch (16 July 622 CE in the proleptic Gregorian calendar) and maps it to the Gregorian date. The algorithm accounts for the Tabular Islamic Calendar cycle of 30 years (containing 11 leap years of 355 days). This method yields astronomical accuracy to within one day of the official Umm Al-Qura calendar in most months.

The converter uses a precise Tabular Islamic Calendar algorithm, which is mathematically accurate for astronomical purposes. The official Umm Al-Qura calendar (Saudi Arabia's government standard) may differ by one day in certain months because it factors in actual crescent moon visibility criteria rather than a fixed mathematical formula. For legal or government documents in Saudi Arabia, always verify against the official Umm Al-Qura calendar published by KACST.
