The Islamic calendar has 12 months alternating 30 and 29 days. In a 354-day common year, Dhu al-Hijjah has 29 days; in a 355-day leap year (11 out of every 30), it gets 30.

About the algorithm
Conversion uses the Tabular Islamic Calendar (Kuwaiti algorithm, type IIc), the same arithmetic calendar shipped in the .NET HijriCalendar and the ICU islamic-civil locale. It is a purely mathematical approximation of the lunar months. Religious dates set by crescent moon sighting (the Umm al-Qura calendar used in Saudi Arabia, and local moon-sighting committees elsewhere) can differ from this tabular result by one or two days. Use this converter for historical dates, document timestamps, calendar planning, and general reference. For Ramadan start, Eid al-Fitr, or Eid al-Adha dates in a specific country, check with the official local announcement.

About this tool
Hijri Date Converter is a two-way bridge between the Gregorian calendar and the Hijri (Islamic) lunar calendar. It uses the Tabular Islamic Calendar (Kuwaiti algorithm, type IIc), the same arithmetic calendar that powers the .NET HijriCalendar and the ICU islamic-civil locale. Pick a Gregorian date and read the matching Hijri date instantly, or enter a Hijri year, month, and day and get the matching Gregorian date back, plus the weekday in English and Arabic, the Julian Day Number, whether the Hijri year is a leap year (11 out of every 30), and how many days the chosen Hijri month contains. Each Hijri month is shown with its English name, Arabic name, and traditional meaning, so the result is useful for historical research, document timestamps, calendar planning, baby age conversions, and Islamic month reference. Because the Tabular Islamic Calendar is a purely mathematical approximation of crescent moon sightings, the result for any given day can differ by one or two days from the Umm al-Qura calendar published in Saudi Arabia or from local moon-sighting committees elsewhere. The tool flags this explicitly so the difference between the calendrical date and the religiously observed date is never hidden. Every conversion runs in your browser; the date you enter never leaves your device.
