What Are the Four Sacred Months in the Hijri Calendar — and Where Do They Fall?
The short answer
The four sacred months of the Hijri year are Dhu al-Qa'dah (month 11), Dhu al-Hijjah (month 12), Muharram (month 1), and Rajab (month 7). Three run consecutively across the turn of the year; Rajab stands alone in the middle. In English they are sometimes called the forbidden months, a loose rendering of the Arabic al-ashhur al-hurum — the long-standing convention being that fighting was suspended while they lasted.
This page is about terminology and calendar mechanics only. Questions about religious obligation or observance during these months belong with a qualified scholar.
Where they sit in the year
- Muharram — month 1, the opening month of the Hijri year
- Rajab — month 7
- Dhu al-Qa'dah — month 11
- Dhu al-Hijjah — month 12, the month in which Hajj takes place
Summary: months 11, 12, and 1 form one consecutive block, and Rajab sits by itself in the second half of the year.
Why their Gregorian dates never repeat
The Hijri calendar is purely lunar. Each month is tied to a lunation and runs 29 or 30 days, so twelve months come to roughly 354 days — about eleven days short of a Gregorian year, as set out by the U.S. Naval Observatory's Islamic calendar reference. The practical effect: a sacred month arrives about eleven days earlier on the Gregorian calendar each year, and works its way through all four seasons over roughly a third of a century.
That also means there is no fixed answer to "what month is Rajab in?" — only a fixed answer for a given Hijri year. Our page on how the Hijri calendar works walks through the drift in more detail, and why the Hijri calendar has no 13th month explains why no leap month is inserted to stop it.
Summary: the dates move because the lunar year is shorter and is never corrected back to the solar year.
What the month names mean
- Dhu al-Qa'dah — literally the one of sitting, a reference to settling down rather than traveling or campaigning
- Dhu al-Hijjah — the one of the pilgrimage
- Muharram — from the same root as haram, meaning made sacred or set apart
- Rajab — from a root carrying the sense of respect or awe
For Arabic script, transliteration variants, and the 29/30-day pattern, see the 12 Hijri month names in Arabic.
Summary: two of the four names describe conduct, one names the pilgrimage, and one names the quality of being set apart.
How this shows up in trip planning
Only one of the four is fixed to a travel event: Hajj falls in Dhu al-Hijjah, and the permits, quotas, and seasonal rules around it are published by the Saudi Ministry of Hajj and Umrah. Umrah is not tied to a sacred month and is performed through the year, though availability narrows around the Hajj period — see whether you can perform Umrah any time of year and how Hajj and Umrah differ.
Because Dhu al-Qa'dah immediately precedes Dhu al-Hijjah, late Dhu al-Qa'dah is often when Makkah traffic and accommodation demand begin climbing. That is a logistics observation, not a rule.
Summary: treat Dhu al-Hijjah as the fixed point in the calendar and plan the months on either side of it around that.
Checking the dates for a specific year
For any Hijri year, read the month boundaries off Saudi Arabia's official calendar authority, the Umm al-Qura calendar, rather than a third-party widget. If you need to line a Hijri month up with US dates, converting Hijri dates to Gregorian explains why two converters can disagree by a day.
Summary: name the Hijri year first, then look up the month boundaries from the official calendar.
