Islamic Months Guide, All 12 Hijri Months Explained
Complete guide to the 12 months of the Islamic (Hijri) calendar. Sacred months, key dates, fasting recommendations, and significance of each month with Quranic and Hadith sources.
The Islamic year has 12 lunar months totalling 354-355 days. Four are classified as sacred (haram), Muharram, Rajab, Dhu al-Qi'dah, and Dhu al-Hijjah, during which fighting is forbidden. Ramadan (month 9) is the month of fasting; Dhu al-Hijjah (month 12) contains Hajj.
Read the significance, major events, and recommended deeds of each month below.
The 12 Islamic Months
Meaning: Sacred / Forbidden
First month of the Islamic year. One of four sacred months when fighting is prohibited.
Key Dates
- • 1st, Islamic New Year
- • 10th, Day of Ashura (recommended fast)
Fasting Guidance
Fasting on 10th Muharram (Ashura) expiates the sins of the previous year (Muslim 1162). Fast 9th+10th or 10th+11th to differ from Jewish practice.
How the Islamic Calendar Works
The Gregorian calendar follows the sun. The Islamic calendar follows the moon. That single difference changes everything.
Each Islamic month begins when the new crescent moon (hilal) is sighted after the astronomical new moon. A lunar cycle is approximately 29.5 days, so each month alternates between 29 and 30 days. Twelve lunar months give a year of about 354 days, roughly 11 days shorter than the solar year.
This means Islamic dates migrate backwards through the Gregorian calendar over a 33-year cycle. Ramadan in a British summer means 18+ hour fasts; 16 years later, it falls in winter with 8-hour fasts. No Muslim community is permanently stuck with the hardest or easiest fasting conditions, the system is inherently fair.
The calendar starts from the Hijra, the Prophet Muhammad's ﷺ migration from Makkah to Madinah in 622 CE. The current Islamic year is 1447 AH (Anno Hegirae). The decision to start from the Hijra was made by Umar ibn al-Khattab (may Allah be pleased with him) during his caliphate, as it was the defining moment that established the Muslim community as a political entity.
The Four Sacred Months
Allah says: "Indeed, the number of months with Allah is twelve 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" (Quran 9:36).
| Month | Position | Why Sacred | Practical Significance |
|---|---|---|---|
| Dhul Qa'dah | 11th | Pre-Hajj truce month for safe travel | Pilgrims travel to Makkah without fear of attack |
| Dhul Hijjah | 12th | The month of Hajj | Contains the best 10 days of the year + Eid al-Adha |
| Muharram | 1st | Post-Hajj truce for safe return home | Contains Ashura (10th), recommended fast |
| Rajab | 7th | Standalone sacred month | Spiritual preparation for the Ramadan season |
"Do not wrong yourselves during them" means that sins during the sacred months are graver, and good deeds carry more weight. It's not that other months don't matter, it's that these four carry a multiplier.
Your Annual Voluntary Fasting Guide
Beyond Ramadan, the Prophet ﷺ taught a rhythm of voluntary fasting throughout the year. Here's when to fast and the reward for each:
| When | What | Reward | Source |
|---|---|---|---|
| Every Monday & Thursday | Weekly voluntary fast | Deeds presented to Allah on these days | Nasai 2358 |
| 13th, 14th, 15th of each month | Ayyam al-Beedh (white days) | Like fasting the entire month | Nasai 2345 |
| 6 days of Shawwal | After Eid al-Fitr | Like fasting the entire year | Muslim 1164 |
| 9th Dhul Hijjah | Day of Arafat (non-pilgrims) | Expiates sins of 2 years | Muslim 1162 |
| 10th Muharram | Ashura (+ 9th or 11th) | Expiates sins of previous year | Muslim 1162 |
| Most of Sha'ban | Pre-Ramadan fasting | Month when deeds are presented to Allah | Nasai 2357 |
| Alternate days year-round | Fast of Dawud (David) | The most beloved fast to Allah | Bukhari 1977 |
Important: fasting is prohibited on Eid al-Fitr (1st Shawwal), Eid al-Adha (10th Dhul Hijjah), and the Days of Tashreeq (11th-13th Dhul Hijjah).
The Spiritual Year at a Glance
Think of the Islamic year as having a rhythm, a spiritual heartbeat with peaks and valleys:
Muharram, Rabi' al-Awwal (months 1-3)
Fresh start. Ashura fast, Prophetic birthday. A time for renewal and gratitude. The year begins with the sacred month of Muharram and the energy of Ashura.
Rabi' ath-Thani, Jumada (months 4-6)
The quiet season. No major events, an excellent time for consistent daily worship, Quran reading, and building spiritual habits without the pressure of special occasions.
Rajab, Sha'ban (months 7-8)
The countdown. Sacred Rajab, then Sha'ban's intensive fasting. The Prophet ﷺ would increase his worship noticeably during these two months. Your Ramadan preparation starts here.
Ramadan (month 9)
The peak. Obligatory fasting, Laylat al-Qadr, Taraweeh, charity. The spiritual summit of the year. Everything before was preparation; everything after is building on the gains.
Shawwal (month 10)
Eid al-Fitr celebration, then 6 days of Shawwal fasting. The transition from Ramadan intensity back to normal life, but better than before.
Dhul Qa'dah, Dhul Hijjah (months 11-12)
Hajj season. Two sacred months culminating in the best 10 days of the year, the Day of Arafat, and Eid al-Adha. The year's grand finale.
Common Misconceptions
Safar is an unlucky month
The Prophet ﷺ explicitly rejected this: 'There is no [bad omen in] Safar' (Bukhari 5757). This was a pre-Islamic superstition. No month is inherently lucky or unlucky in Islam.
You must fast the entire month of Rajab
There is no authentic hadith singling out Rajab for continuous fasting. The Prophet ﷺ didn't fast the whole of any month except Ramadan. Voluntary fasts in Rajab are fine, just don't treat it as an obligation.
Shab-e-Barat (15th Sha'ban) is like Laylat al-Qadr
Scholars differ significantly on 15th Sha'ban. Some consider it virtuous (based on hadith in Ibn Majah); others classify those hadith as weak. It's nowhere near the status of Laylat al-Qadr, which the Quran explicitly calls 'better than 1,000 months.'
Islamic New Year should be celebrated like Gregorian New Year
There's no evidence the Prophet ﷺ or companions celebrated 1st Muharram as a festival. It's a time for reflection and gratitude, not fireworks and parties. The only two celebrations in Islam are Eid al-Fitr and Eid al-Adha.
Fasting the Day of Arafat is only for Hajj pilgrims
It's the opposite. Pilgrims should NOT fast on Arafat (they need energy for the rituals). Non-pilgrims are encouraged to fast, the reward is expiation of the previous and coming year's sins (Muslim 1162).
You can fast on Eid if you want extra reward
Fasting on Eid al-Fitr and Eid al-Adha is explicitly prohibited (Bukhari 1993). The Prophet ﷺ forbade it. Eid is meant for celebration, eating, and gratitude.
