Hijri to Gregorian Converter (and Gregorian to Hijri)

Date Converter

Convert Between Hijri and Gregorian Dates

This free Hijri to Gregorian converter changes dates from the Islamic (Hijri) calendar to the Gregorian calendar, and from Gregorian to Hijri, in both directions. It is fast, accurate, and based on the official Umm al-Qura calendar. Because the Hijri calendar is also called the Islamic or Hegira calendar, and the Gregorian calendar is known in Arabic as the Miladi calendar, this tool also works as an Arabic (Islamic) date to English date converter.

If you want to know how old you are in the Islamic calendar, check out our Hijri Age Calculator. Or, to find the time between two specific days, try our Date Difference Calculator.

How to Use the Date Converter

  • Choose the direction (Gregorian to Hijri, or Hijri to Gregorian).
  • Enter the day, month, and year correctly.
  • Click "Convert Date" to get the exact result instantly.

How Accurate is the Conversion?

This tool uses the official Umm al-Qura rules from Saudi Arabia. For dates between 30 April 1900 and 16 November 2077 AD (1318 to 1500 Hijri) the result is an exact match. Dates outside this range use an approximate astronomical calculation that may differ by one day.

Hijri to Gregorian Formula

You can estimate the Gregorian year from the Hijri year with this formula:

Gregorian year ≈ (Hijri year × 0.970224) + 621.5774

Example: for 1447 AH → (1447 × 0.970224) + 621.5774 ≈ 2025.6, so 1447 AH falls around the middle of 2025 CE. The formula estimates the year only; the converter above gives the exact day and month using Umm al-Qura.

What is the Hijri Calendar?

The Hijri (Islamic) calendar is a lunar calendar that follows the moon phases. Muslims worldwide use it to find the correct days for religious events like Ramadan and Eid. A lunar year has 12 months but only 354 or 355 days, so Hijri dates move back about 11 days each year compared with the Gregorian calendar.

Frequently Asked Questions

How do I convert a Hijri date to Gregorian?

Choose "From Hijri" above, enter the Hijri (Islamic) day, month, and year, then press "Convert Date". You will instantly get the matching Gregorian date along with the day of the week.

How do I convert a Gregorian date to Hijri?

Choose "From Gregorian" above, enter your normal (Gregorian) day, month, and year, then press "Convert Date". You will see the matching Hijri (Islamic) date right away.

What is the Umm al-Qura calendar?

Umm al-Qura is the official Hijri calendar of Saudi Arabia, used to set the start of each Islamic month and religious events. Our converter follows it exactly within the 1318–1500 AH range for maximum accuracy.

What year is 1447 AH in the Gregorian calendar?

The Hijri year 1447 begins on 26 June 2025 CE and runs until mid-June 2026 CE, because the Hijri (lunar) year is about 11 days shorter than the Gregorian (solar) year.

Are the Hijri, Islamic, Hegira, and Miladi calendars the same?

Hijri, Islamic, and Hegira all refer to the same lunar calendar. "Miladi" is the Arabic name for the Gregorian (Christian/CE) calendar, sometimes called the English or "normal" calendar. This tool converts between the two in both directions, so it also works as an Arabic date to English date converter.

Why might the result differ by one day from another website?

Within the Umm al-Qura range (1318–1500 AH) our result matches the official calendar and Saudi Arabia's Ramadan and Eid dates. Some other sites use the arithmetic (tabular) Islamic calendar, which can differ by a day. Outside the range we use an approximate astronomical calculation.
