About the Hijri Islamic Calendar

The Hijri Calendar is a lunar calendar used by Muslims worldwide to determine the proper days of Islamic holidays and rituals, such as the annual period of fasting and the proper time for the Hajj pilgrimage. This interactive tool provides an easy way to view the Islamic months and their corresponding Gregorian dates.

Tabular vs. Observational Calendars

This tool uses a tabular Islamic calendar, which is a rule-based variation of the Islamic calendar. It runs on a fixed mathematical algorithm and is not based on the actual sighting of the moon, making it predictable and ideal for long-term planning. Traditional communities rely on the physical sighting of the crescent moon, which can cause dates to vary by one or two days. Our "regional offset" feature allows you to adjust the calendar to match your local community's observations.

Key Features

  • Dual Calendar View: See both Hijri and Gregorian dates in a single, clear layout.
  • Regional Offset Control: Adjust the calendar by +/- 2 days to align with local moon-sightings.
  • Key Date Integration: See important dates like Ramadan and Eid for the selected year and add them to your personal calendar.
  • Easy Navigation: Quickly browse through different months and years.
