Hijri Gregorian Calendar — Prayer Times & Islamic Tools
Accurate dual-calendar system, prayer times for any location, date conversion tools, and more.
📅 Dual Hijri-Gregorian Calendar
View and navigate both the Hijri (Islamic) and Gregorian calendars side by side. Our calendar displays both dates simultaneously, making it easy to plan around Islamic holidays, events, and important dates.
The Hijri calendar, also known as the Islamic lunar calendar, consists of 12 months based on lunar cycles. Each month begins with the sighting of the new crescent moon. Our calendar uses the Umm al-Qura calculation method, the same system used in Saudi Arabia, to ensure day-accurate Hijri dates.
Key Features
- Accurate Hijri Dates — Based on the Umm al-Qura algorithm with manual adjustment support for local moon sighting differences.
- Islamic Events & Holidays — Automatic display of events like Ramadan, Eid al-Fitr, Eid al-Adha, Mawlid, and many more.
- Dual Date Display — Every Gregorian date shows its corresponding Hijri date, and vice versa.
- Month & Year Navigation — Easily navigate to any month in either calendar system.
Understanding the Hijri Calendar
The Hijri calendar has 12 months: Muharram, Safar, Rabi' al-Awwal, Rabi' al-Thani, Jumada al-Ula, Jumada al-Thani, Rajab, Sha'ban, Ramadan, Shawwal, Dhul Qi'dah, and Dhul Hijjah. A Hijri year is approximately 354 or 355 days, making it about 11 days shorter than the Gregorian year. This means Islamic occasions shift earlier each Gregorian year.

The Five Daily Prayers
- Fajr (الفجر) — The pre-dawn prayer, beginning at true dawn when a thin line of light appears on the horizon.
- Dhuhr (الظهر) — The midday prayer, starting when the sun passes its zenith (highest point).
- Asr (العصر) — The afternoon prayer, determined when the shadow of an object equals its length (Shafi'i) or twice its length (Hanafi).
- Maghrib (المغرب) — The evening prayer, beginning immediately after sunset.
- Isha (العشاء) — The night prayer, starting when the red twilight disappears from the sky.
How Prayer Times Are Calculated
Prayer times are determined by the position of the sun relative to a specific geographic location. They vary daily based on latitude, longitude, altitude, and the time of year. Locations closer to the poles experience greater variation between summer and winter prayer times. Our calculations account for atmospheric refraction and seasonal changes to provide the most accurate results possible.
🛠️ Date Conversion & Calculation Tools
Hijri-Gregorian Date Converter
Convert any date between the Hijri (Islamic) and Gregorian calendar systems instantly. Whether you need to find the Gregorian equivalent of a Hijri birthday, or determine which Hijri date corresponds to an upcoming Gregorian event, our converter handles it accurately.
The conversion uses the Umm al-Qura data tables for dates within the supported range, with astronomical algorithms as a fallback for historical dates. Results include the day of the week, making it easy to plan ahead.
Age Calculator (Hijri & Gregorian)
Calculate your exact age in both calendar systems. Enter your birth date in either the Hijri or Gregorian calendar, and get a detailed breakdown including years, months, days, total weeks, and total days lived. Because the Hijri year is shorter than the Gregorian year, your Hijri age will always be slightly higher than your Gregorian age.
This tool is particularly useful for determining your age according to the Islamic calendar, which is relevant for religious obligations like Zakat and Hajj eligibility.
Date Difference Calculator
Find the exact difference between any two dates in either the Hijri or Gregorian calendar. Results are shown in years, months, days, total weeks, and total days. This is useful for planning events, calculating durations, or finding out how many days remain until an important occasion.
❓ Frequently Asked Questions
What is the Hijri calendar?
The Hijri (Islamic) calendar is a lunar calendar consisting 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 (Ramadan) and the proper time for the Hajj pilgrimage. The calendar began in 622 CE, marking the migration (Hijra) of Prophet Muhammad ﷺ from Mecca to Medina.
How accurate are the prayer times?
Our prayer times are calculated using well-established astronomical algorithms and support multiple calculation methods (Umm al-Qura, MWL, ISNA, Egyptian, and more). They are accurate to within 1-2 minutes for most locations. Times may vary slightly from your local mosque's posted times due to differences in calculation methods or local conventions.
Why is my Hijri age different from my Gregorian age?
A Hijri year is approximately 11 days shorter than a Gregorian year because it follows the lunar cycle. Over time, this difference accumulates, so someone who is 30 Gregorian years old would be approximately 31 Hijri years old. Our Age Calculator shows both ages precisely.
Is this app available on mobile?
Yes! The Hijri Gregorian Calendar app is available on both Android (Google Play) and iOS (App Store) with additional features including prayer notifications, home screen widgets, Qibla direction, and smart event management.
