The special days of the Islamic year
The Islamic year has several sacred and notable days, set by the lunar Hijri calendar, so they move about eleven days earlier each Gregorian year. The four sacred months are Dhul-Qadah, Dhul-Hijjah, Muharram, and Rajab.
Dates and differences
The dates shown are calculated from the Umm al-Qura calendar and may differ by a day from local moon sighting. Some occasions, such as the Mawlid and mid-Shaban, are observed by some Muslims and not by others, and the exact date of events like Isra and Miraj is not firmly established. They are listed here for reference, not as a ruling.
The most emphasized days
Among the most emphasized in authentic practice are the Day of Arafah (fasting for those not on Hajj), Ashura (fasting the ninth and tenth of Muharram), seeking Laylat al-Qadr in the last ten nights of Ramadan, and the two Eids.
Living the year with intention
The Islamic year is not a flat line with two holidays; it has a landscape. Some of its days carry extra recommended worship - the fast of Ashura, the fast of Arafah for those not on Hajj, fasting in the first nine days of Dhul-Hijjah (and every good deed in all ten), the white days of every month. Some carry history worth teaching children on the day itself rather than from a textbook. And some, like the sacred months, change the weight of deeds. Knowing where these days sit in your civil calendar is the difference between meeting them prepared and hearing about them the morning after. A year lived with a map simply holds more than a year lived by surprise.
Using this calendar
The tool takes each notable Hijri date and resolves it to its next occurrence in your civil calendar, sorted by how soon it arrives, so the top of the list is always what to prepare for next. One tap downloads the whole set as an .ics file that drops into your phone or work calendar - the reminders then come to you. Dates follow the calculated Umm al-Qura calendar with the usual plus-or-minus-a-day sighting caveat, so treat the entries as planning anchors and confirm worship-critical dates with your local mosque. Everything runs on your device.
