The Hijri Calendar

The Islamic calendar is purely lunar. It consists of 12 months in a year of 354 or 355 days. It is used to determine the proper days of Islamic holidays and rituals, such as the annual period of fasting and the proper time for the Hajj.

11 Days Shorter

Because the lunar year is roughly 11 days shorter than the solar Gregorian year, Islamic dates rotate backwards through the seasons over a 33-year cycle. This is why Ramadan happens in different seasons over a lifetime.

How Does the Hijri to Gregorian Conversion Work?

The Hijri (Islamic) calendar began in the year 622 CE, the year the Prophet Muhammad ï·º migrated (made Hijrah) from Makkah to Madinah. This converter uses algorithmic mathematical formulas (Umm al-Qura standard and standard tabular Islamic calendar calculations) to accurately map Hijri dates to the Gregorian solar calendar.

Important Note on Moon Sighting

While mathematical conversions are highly accurate for historical dates and general planning, in Islamic Fiqh (jurisprudence), the start of a new month (especially Ramadan, Shawwal, and Dhu al-Hijjah) is officially determined by the physical sighting of the new moon. Therefore, actual dates for Islamic rituals may vary by 1 day depending on global or local moon sighting.
