Converting dates from the Islamic (Hijri) calendar to the Gregorian (Western) calendar involves understanding the differences between the two systems and applying conversion formulas. The Islamic calendar, based on lunar cycles, begins with the year of the Hijra, the migration of Prophet Muhammad from Mecca to Medina in 622 CE. It consists of 12 months of 29 or 30 days, totaling either 354 or 355 days in a year, making it shorter than the Gregorian calendar.
To convert a date from the Islamic calendar to the Gregorian calendar, you need to know the year, month, and day in the Islamic calendar and then apply a conversion formula. One common method is to use online conversion tools or calendars specifically designed for this purpose. However, if you prefer to do the conversion manually, you can use the following steps:
-
Determine the Islamic Year (AH): The Islamic year is denoted as AH, which stands for “Anno Hegirae,” meaning “in the year of the Hijra.”
-
Find the Gregorian Year (AD): The Hijri year typically overlaps two Gregorian years, as the Islamic calendar is shorter. For example, the Islamic year 1443 AH spans parts of 2021 AD and 2022 AD.
-
Adjust for Leap Years: The Gregorian calendar follows a solar year and includes leap years to account for the extra quarter day each year, making it longer than the lunar-based Islamic calendar. Therefore, you may need to adjust for leap years when converting dates.
-
Calculate the Difference in Days: Determine the number of days between the start of the Islamic year and the target date. This may vary depending on the month and year in both calendars.
-
Apply the Conversion Formula: Add the calculated number of days to the corresponding Gregorian date. Be mindful of any differences in the number of days between the two calendars.
-
Verify the Result: Double-check the converted date to ensure accuracy, especially when dealing with boundary dates between two Gregorian years or when leap years are involved.
It’s worth noting that while the Islamic calendar is widely used in Muslim-majority countries for religious and cultural purposes, the Gregorian calendar is the standard system for international business, communications, and civil affairs. Therefore, understanding how to convert dates between the two systems can be helpful in various contexts, such as travel, commerce, and historical research.
Additionally, some historical events or documents may use both Islamic and Gregorian dates, requiring conversion for accurate interpretation and analysis. By familiarizing yourself with the principles of date conversion and utilizing available resources, you can effectively navigate between these two calendar systems as needed.

The Islamic (Hijri) calendar, unlike the Gregorian calendar, is a lunar calendar based on the cycles of the Moon. It consists of 12 months, each of which alternates between 29 and 30 days, totaling either 354 or 355 days in a year. The beginning of the Islamic calendar dates back to the Hijra, the migration of the Prophet Muhammad from Mecca to Medina in 622 CE (Common Era), marking the start of the Islamic era.
The Islamic calendar months are:
- Muharram: Considered the holiest month after Ramadan, it marks the start of the Islamic year.

Converting dates from the Islamic calendar to the Gregorian calendar requires accounting for the differences in the lengths of the two calendars’ years and months. While the Islamic calendar is purely lunar, with each month beginning with the sighting of the new moon, the Gregorian calendar follows the solar year, with months based on the Earth’s orbit around the Sun.
To convert a date from the Islamic calendar to the Gregorian calendar, one typically uses a conversion formula that takes into account the year, month, and day in the Islamic calendar and calculates the corresponding date in the Gregorian calendar. This conversion often involves considering leap years in the Gregorian calendar and adjusting for differences in the lengths of months between the two calendars.
Several online tools and applications are available for easily converting dates between the Islamic and Gregorian calendars. These tools often allow users to input a date in the Islamic calendar and receive the corresponding date in the Gregorian calendar, simplifying the conversion process.
Understanding how to convert dates between the Islamic and Gregorian calendars can be beneficial for various purposes, including scheduling events, planning religious observances, and studying historical documents and events. By familiarizing oneself with the principles of date conversion and utilizing available resources, individuals can effectively navigate between these two calendar systems as needed.
