How conversion works
Convert Hijri and Gregorian dates clearly
Choose the calendar you are starting from, enter the day, month, and year, and click Convert. The result shows the matching date in the other calendar so you can verify the relationship quickly and compare the values side by side.
Examples
What a conversion result means
If you enter a Hijri date such as Ramadan in one of the later years, the tool calculates the corresponding Gregorian date for that lunar month. If you start from a Gregorian date, the reverse conversion returns the matching Hijri date based on the same calculation method.
Calendar basics
Why the dates can differ
The Hijri calendar is lunar, while the Gregorian calendar is solar. A lunar year is shorter than a solar year, so Islamic dates move through the Gregorian calendar over time. Local moon-sighting practices and calculation conventions can also shift the start of a month by a day.
FAQ
Frequently asked questions
Can I convert Gregorian to Hijri?
Yes. Select the Gregorian source calendar, enter the date, and the result will show the matching Hijri date.
Why is the result sometimes a day different?
This converter uses a calculated Hijri date. Local moon-sighting announcements can differ by about one day, especially around the start of a lunar month.
Is this suitable for religious observance?
It is a helpful reference and planning tool. For Ramadan, Eid, and other important observances, confirm the final date with your local authority or community.
