Frequently Asked Questions (FAQ)
What does the Date to Hijri Converter do?
It converts Gregorian dates to Hijri dates and back, instantly.
Why is there an adjustment option?
Local moon sighting can shift the Hijri date by a day or two, so you can adjust the result to match your local calendar.
How is the conversion calculated?
It uses the Kuwaiti algorithm, which converts the date to a Julian day number and then to the Hijri calendar. It is an arithmetic calendar, so the adjustment option covers local moon-sighting differences.
Can I convert a Hijri date back to Gregorian?
Yes. Enter the Hijri day, month and year in the second section and press Convert to Gregorian.
