Convert any Gregorian (English) date to the Islamic Hijri calendar — day, month name in English, Arabic and Bangla, plus the Hijri year (AH).

About this converter

The Hijri calendar is the Islamic lunar calendar of 12 months totalling 354 or 355 days a year. Year 1 AH corresponds to 622 CE, the year of the Prophet Muhammad\'s migration (Hijra) from Mecca to Medina. This tool converts any Gregorian (English) date into its Hijri equivalent using the Aladhan calendar API, with results in English, Arabic, and Bengali script.

How the conversion works

Unlike a fixed mathematical algorithm, this tool queries the Aladhan calendar API for the requested month, then looks up the specific day. Aladhan uses the Umm al-Qura calculated calendar, which is the standard reference in Saudi Arabia and widely accepted across South Asia. Results are cached aggressively because the Hijri-for-a-given-Gregorian mapping never changes.

The 12 Hijri months

1. Muharram (مُحَرَّم), 2. Safar (صَفَر), 3. Rabi al-awwal (رَبيع الأَوَّل), 4. Rabi al-thani (رَبيع الثاني), 5. Jumada al-awla (جُمادى الأُولى), 6. Jumada al-akhirah (جُمادى الآخرة), 7. Rajab (رَجَب), 8. Shaban (شَعْبان), 9. Ramadan (رَمَضان), 10. Shawwal (شَوّال), 11. Dhu al-Qadah (ذو القعدة), 12. Dhu al-Hijjah (ذو الحجة).

Worked example

Take 20 March 2026. The Aladhan calendar maps this to 1 Ramadan 1447 AH — the beginning of fasting month — in the Umm al-Qura standard. Local moonsighting committees in India, Bangladesh, and Pakistan may shift this by ±1 day.

English to Hijri date FAQs

How do I convert an English date to a Hijri date?

Choose any Gregorian (English) date in the converter above. The page returns the corresponding Islamic Hijri date — day, month name (Arabic and English), and Hijri year (AH) — based on the official Umm al-Qura / observed-moon data from the Aladhan API.

What is the Hijri (Islamic) calendar?

The Hijri calendar is a lunar calendar of 12 months totalling 354 or 355 days. It started in 622 CE with Prophet Muhammad's migration (Hijra) from Mecca to Medina. The 12 months are: Muharram, Safar, Rabi al-awwal, Rabi al-thani, Jumada al-awla, Jumada al-akhirah, Rajab, Shaban, Ramadan, Shawwal, Dhu al-Qadah, and Dhu al-Hijjah.

Why is the Hijri date sometimes different from another source?

Because Islamic months traditionally begin with the local sighting of the new crescent moon, the start of a Hijri month can differ by ±1 day between countries (Saudi Arabia, India, Bangladesh, Pakistan often differ). This tool uses the Aladhan calendar based on the Umm al-Qura calculation, which is widely accepted in South Asia.
