The 12 Hijri Months of the Islamic Calendar
Introduction
In the calm silence of the mosque, the imam addresses the congregation:
“My brothers and sisters, have you ever noticed that Ramadan never falls in the same month of the year on the calendar you use for school or work?”
The question echoes in every heart. Then the imam continues:
“That’s because we follow a different calendar — a lunar calendar known as the Hijri or Islamic calendar.
It has 12 months — not 365 days, but 354.
Twelve months that shape our spiritual lives: Ramadan, Hajj, Eid al-Fitr, Eid al-Adha…
Twelve months that are not just measures of time, but milestones of faith.”
So, what are these Hijri months?
Which four months are considered sacred in the Qur’an?
And how can today’s mosques use the Islamic lunar calendar to better guide their communities — with the help of modern tools like Masjidbox Calendars?
Quick Definition of the Hijri Months
The Hijri months, also known as the Islamic months, are the 12 months of the Islamic lunar calendar.
They begin with Muharram and end with Dhu al-Hijjah, and include four sacred months mentioned in the Qur’an: Muharram, Rajab, Dhu al-Qa‘dah, and Dhu al-Hijjah.
This lunar calendar shapes the rhythm of Muslim life — marking sacred events such as Ramadan, Hajj, Eid al-Fitr, and Eid al-Adha.
What Are the 12 Months of the Hijri Calendar?
The imam asks gently,
“My brothers and sisters, do you know how many months there are in our Islamic calendar?”
A worshipper answers confidently:
“Twelve, Shaykh — just like in the Gregorian calendar.”
The imam smiles:
“Exactly, my brother. Twelve months as well — but their names existed long before Islam, and each carries a deep spiritual meaning.”
Allah ﷻ says in the Qur’an:
“Indeed, the number of months with Allah is twelve [lunar] months in the register of Allah,
from the day He created the heavens and the earth; of these, four are sacred.”
(Surah At-Tawbah, verse 36)
Origin of the Hijri Calendar
The imam explains:
“The Hijri calendar — also called the Islamic lunar calendar — was officially established during the caliphate of ʿUmar ibn al-Khattab (may Allah be pleased with him).
It was set to begin from the Hijrah (migration) of the Prophet Muhammad ﷺ from Mecca to Medina — an event that took place on the 10th of Rabiʿ al-Awwal, 622 CE (September 21, 622).
For practical use, the calendar’s starting point was fixed at the 1st of Muharram of that same year — equivalent to July 16, 622 CE.”
He continues:
“This calendar follows the moon’s cycle, which is why its months are shorter than those of the solar (Gregorian) calendar.
But the names of the months predate Islam — they come from pre-Islamic Arabia, and Islam gave them a new spiritual dimension.”
The 12 Hijri (Islamic) Months and Their Meanings
Here are the 12 months of the Hijri calendar, their Arabic names, and their meanings:
-
Muharram (مُحَرَّم) – The first month and one of the four sacred months. The 10th, Ashura, is a day of fasting and reflection.
-
Safar (صَفَر) – Means “empty” — when Arabs would travel and homes were left vacant.
-
Rabiʿ al-Awwal (رَبِيع ٱلْأَوَّل) – “The first spring”; month of the Prophet Muhammad’s ﷺ birth.
-
Rabiʿ al-Thani (رَبِيع ٱلثَّانِي) – “The second spring,” continuation of the previous.
-
Jumada al-Awwal (جُمَادَىٰ ٱلْأُولَىٰ) – A winter month symbolizing dryness or frozen water.
-
Jumada al-Thani (جُمَادَىٰ ٱلثَّانِيَة) – “The second Jumada,” extending the same meaning.
-
Rajab (رَجَب) – A sacred month linked to Isra’ and Mi‘raj.
-
Shaʿban (شَعْبَان) – Month of spiritual preparation before Ramadan.
-
Ramadan (رَمَضَان) – Month of fasting; name comes from ramad, “heat” — symbol of purification.
-
Shawwal (شَوَّال) – Month of Eid al-Fitr; name comes from the decrease of camel milk.
-
Dhu al-Qaʿdah (ذُو ٱلْقَعْدَة) – Sacred month when battles ceased and people rested before Hajj.
-
Dhu al-Hijjah (ذُو ٱلْحِجَّة) – Month of Hajj and Eid al-Adha; culmination of faith and unity.
The Four Sacred Months in Islam
Allah ﷻ says:
“Indeed, the number of months with Allah is twelve [lunar] months in the register of Allah [from] the day He created the heavens and the earth;
of these, four are sacred. That is the correct religion, so do not wrong yourselves during them.”
(Surah At-Tawbah, 9:36)
The four sacred months (Al-Ashhur al-Hurum) are:
-
Muharram (مُحَرَّم) – The month of peace and reflection.
-
Rajab (رَجَب) – The month of divine mercy, linked to Isra’ and Mi‘raj.
-
Dhu al-Qaʿdah (ذُو ٱلْقَعْدَة) – The month of rest and preparation.
-
Dhu al-Hijjah (ذُو ٱلْحِجَّة) – The month of Hajj and Eid al-Adha.
These months were established to promote peace, unity, and reflection — guiding Muslims toward patience, self-restraint, and righteousness.
The Islamic vs. Gregorian Calendar
A worshipper asks:
“Shaykh, why does Ramadan never fall in the same month on our usual calendar?”
The imam replies:
“The Hijri calendar has 354 days, while the Gregorian calendar has 365.
That’s why Islamic months move about 10 to 11 days earlier each year.”
Another asks:
“How do we know exactly when a month begins, such as Ramadan?”
The imam answers with the hadith of the Prophet ﷺ:
“Fast when you see the new moon and break your fast when you see it.
And if the sky is cloudy, then complete the number of days of Shaʿban as thirty.”
(Sahih al-Bukhari & Sahih Muslim)
Why the Hijri Calendar Matters for Mosques
The imam explains:
“Because every part of mosque life depends on it — Ramadan, Hajj, Eid, Jumu’ah schedules, weddings, funerals.
Without a clear Hijri reference, confusion begins.”
He continues:
-
Plan events — Ramadan iftars, Eid prayers, Hajj announcements.
-
Communicate — via digital screens and announcements.
-
Unite the community — through shared time and worship.
“Imagine announcing Eid a day late — some people pray, others wait. Confusion and frustration follow. That’s why a reliable Islamic calendar keeps unity.”
Simplifying Hijri Date Management in Mosques
A worshipper asks:
“Shaykh, how can we avoid mistakes and make things easier?”
The imam smiles:
“Alhamdulillah, our mosque now uses Masjidbox Calendars — a smart tool that displays a clear, accurate Hijri calendar, fully customized for our mosque.
It’s available as a PDF or directly on digital screens — automatically updated with every new lunar month.”
No more confusion — every Hijri date is precise, synchronized, and easy to follow.
