JAKARTA (26/06/2026)

Just last week, Muslims around the world welcomed Muharram, the first month of the Islamic lunar calendar, marking the beginning of a new Hijri year. But behind this new year lies an entire calendar system rich with history, spiritual meaning, and daily practice. One that shapes the rhythm of life for nearly two billion Muslims worldwide.

What Is the Hijri (Islamic Lunar) Calendar?

The Hijri calendar (at-taqwīm al-hijrī in Arabic) is the Islamic lunar calendar used to determine the dates of important religious events, fasts, festivals, and observances in Islam. It is also called the Islamic calendar or the Muslim calendar.

The word Hijri comes from Hijra, which refers to the migration of the Prophet Muhammad ﷺ from Mecca to Medina in 622 CE, an event considered the foundational turning point of early Islamic history. That year was designated as year 1 AH (Anno Hegirae, “in the year of the Hijra”), making 2026 CE correspond roughly to 1447–1448 AH.

The calendar consists of 12 lunar months, each beginning with the sighting of the new crescent moon (hilal). Because each month follows the moon’s cycle, a Hijri year is approximately 354 days long, approximately around 10 to 11 days shorter than a solar year.

How Is It Different from the Gregorian Calendar?

Most people around the world use the Gregorian calendar, a solar calendar based on Earth’s revolution around the sun with 365 days per year (366 in leap years). The Gregorian calendar keeps months aligned with the seasons.

The Hijri calendar, by contrast, is purely lunar: it tracks the cycles of the moon, not the sun. This has a few important practical implications:

Islamic months “move” through the seasons: Because the Hijri year is ~11 days shorter, Ramadan, Eid, Hajj, and other Islamic observances gradually shift earlier each year relative to the Gregorian calendar. Ramadan, for example, will eventually cycle through summer, autumn, winter, and spring over a period of roughly 33 years.

The start of a month is tied to moon sightings: Traditionally, the beginning of each Hijri month is determined by the physical sighting of the crescent moon, which is why the date of Eid or Ramadan may differ by one day between countries.

There are no “leap months.” Unlike the Hebrew calendar (another lunar calendar), the Hijri calendar does not add extra months to realign with the solar year.

The Twelve Months of the Hijri Calendar

Here is a guide to each of the twelve Hijri months, their names, meanings, key virtues, and recommended practices.

1. Muharram (مُحَرَّم)

Meaning: “Forbidden” or “Sacred”

Muharram is the first month of the Hijri year and one of the four sacred months in Islam (al-ashhur al-hurum), during which warfare and conflict were historically prohibited. It holds one of the highest ranks in Islamic spiritual significance.

Key Virtues: The Prophet Muhammad ﷺ described Muharram as the best month for voluntary fasting after Ramadan. The 10th of Muharram, known as Ashura, is a day of particular importance and observed by Muslims through fasting as a mark of gratitude, commemorating the day Moses and the Israelites were saved from Pharaoh.

Recommended Practices: Increase voluntary fasting, especially on the 9th and 10th (or 10th and 11th) of Muharram. Engage in additional prayers, remembrance of God (dhikr), and acts of charity.

2. Safar (صَفَر)

Meaning: “Empty” or “Whistling of the Wind”

The name Safar likely refers to the time when ancient Arabs would leave their homes for travel or trade, leaving them empty. Historically, some cultures associated Safar with bad omens, but Islam rejected this notion entirely.

Key Virtues: There is no specific virtue unique to Safar in Islamic texts. However, Islam teaches that time itself is neutral — blessings and difficulties come by the will of God, not by the month one is in.

Recommended Practices: Maintain regular worship. This is a good time to reflect on superstitions or negative thinking patterns and return to trust in God (tawakkul). No specific rituals are prescribed, which itself teaches equanimity.

3. Rabi’ al-Awwal (رَبِيعُ الأَوَّل)

Meaning: “The First Spring”

This is among the most beloved months in the Islamic calendar, as it is the month in which the Prophet Muhammad ﷺ was born celebrated by many Muslims as Mawlid an-Nabi (the Prophet’s Birthday), observed on the 12th of this month.

Key Virtues: The birth of the Prophet is seen as the greatest blessing to humanity in Islamic belief. Many Muslims use this month to deepen their knowledge of the Prophet’s life (seerah) and character.

Recommended Practices: Reading and reflecting on the biography of the Prophet Muhammad ﷺ, sending blessings upon him (salawat), and increasing acts of generosity and kindness — qualities the Prophet exemplified.

4. Rabi’ al-Thani (رَبِيعُ الثَّانِي)

Meaning: “The Second Spring”

Also known as Rabi’ al-Akhir (“the latter spring”), this month follows in the wake of Rabi’ al-Awwal. It does not carry specific prescribed observances in Islamic jurisprudence, but it continues the spirit of the preceding month.

Key Virtues: A time of spiritual continuity. Many Islamic scholars and Sufi traditions commemorate the passing of notable saints during this month, including Sheikh Abdul Qadir al-Jilani, a revered 12th-century scholar.

Recommended Practices: Continue the good deeds and spiritual momentum from Rabi’ al-Awwal. Reflect on the legacies of Islamic scholars and their contributions to knowledge and spirituality.

5. Jumada al-Ula (جُمَادَى الأُولَى)

Meaning: “The First of the Parched Land” or “First Dry Month”

The name Jumada refers to the freezing or drying of water and likely associated with the cold or dry season when these months originally fell in the ancient Arabian calendar. Ula means “the first.”

Key Virtues: Like Rabi’ al-Thani, no specific virtues are prescribed for this month in Islamic texts. It is part of the “ordinary” months of the Islamic year.

Recommended Practices: Maintain consistent daily worship (salah), voluntary fasting on Mondays and Thursdays (a regular Sunnah practice), and give regularly to charity. Use these quieter months to build the foundation of consistent worship.

6. Jumada al-Thani (جُمَادَى الثَّانِي)

Meaning: “The Second Dry Month”

Also called Jumada al-Akhira, this is the sixth month and closes the first half of the Hijri year. Of historical note: the Battle of Mu’tah, the first military encounter between Muslims and the Byzantine Empire is said to have occurred during this month.

Key Virtues: A month of reflection and preparation as the year reaches its midpoint.

Recommended Practices: A good time to evaluate one’s spiritual state at the midpoint of the year. Increase in acts of remembrance, learning, and service to family and community.

7. Rajab (رَجَب)

Meaning: “To Respect” or “To Honor”

Rajab is the second of the four sacred months in Islam. It stands alone (fard) among the sacred months, as the other three are consecutive. It is also associated with a pivotal event in Islamic history: Isra’ wal-Mi’raj, the miraculous night journey of the Prophet Muhammad ﷺ from Mecca to Jerusalem and then to the heavens, believed to have occurred on the 27th of Rajab.

Key Virtues: This is a month for increased devotion and preparation ahead of Ramadan. The Prophet reportedly said, “Rajab is the month of God, Sha’ban is my month, and Ramadan is the month of my Ummah (community).”

Recommended Practices: Increase voluntary fasting, engage in night prayers (qiyam al-layl), reflect on the significance of the Night Journey, and begin mentally and spiritually preparing for Ramadan two months away.

8. Sha’ban (شَعْبَان)

Meaning: “To Spread” or “To Branch Out”

Sha’ban is the eighth month and the direct precursor to Ramadan. It was a month the Prophet Muhammad ﷺ reportedly loved and in which he increased his fasting.

Key Virtues: The Prophet said he would fast more in Sha’ban than in any other month outside of Ramadan. The 15th of Sha’ban (Laylat al-Nisf min Sha’ban, or “Mid-Sha’ban Night”) is considered by many Muslims to be a significant night of divine mercy and forgiveness, though its exact theological status is debated among scholars.

Recommended Practices: Increase voluntary fasting, particularly in the first half of the month. Begin preparing the body and spirit for the discipline of Ramadan — adjusting sleep, diet, and prayer routines. Seek forgiveness and reconcile with those one may have wronged.

9. Ramadan (رَمَضَان)

Meaning: “Scorching Heat” or “Burning”

Ramadan is undoubtedly the most well-known Islamic month globally for good reason. It is the month of obligatory fasting (sawm), one of the Five Pillars of Islam. Every adult Muslim who is physically able is required to abstain from food, drink, smoking, and intimate relations from dawn (Fajr) to sunset (Maghrib) throughout the entire month.

Key Virtues: Ramadan is described in the Quran as the month in which the Quran was revealed. The final ten nights of Ramadan contain Laylat al-Qadr (“the Night of Power”), described in the Quran as better than a thousand months — believed to be the night the first Quranic verses were revealed to the Prophet.

Recommended Practices: Daily fasting, increased Quran recitation, extended night prayers (Tarawih), charity (Zakat al-Fitr at the end of the month), and i’tikaf (spiritual seclusion in the mosque) during the last ten nights. The month ends with Eid al-Fitr — the festival of breaking the fast.

10. Shawwal (شَوَّال)

Meaning: “To Lift” or “Carrying”

Shawwal begins with one of Islam’s most joyous celebrations: Eid al-Fitr on the 1st of Shawwal. After a full month of fasting, Muslims celebrate with communal prayers, feasts, new clothes, and the giving of gifts.

Key Virtues: The first day is a celebration; and the month itself carries a special voluntary fast. The Prophet said that whoever fasts Ramadan and then follows it with six days in Shawwal will have the reward as if they had fasted the entire year.

Recommended Practices: Celebrate Eid with family and community. Then, anytime during Shawwal, fast six voluntary days (they need not be consecutive). Maintain the Quran recitation habits built during Ramadan. Pay Zakat (obligatory charity) if not yet done.

11. Dhu al-Qi’dah (ذُو القَعْدَة)

Meaning: “The Month of Rest” or “Sitting”

Dhu al-Qi’dah is the third of Islam’s four sacred months. Historically, it was a month in which fighting was forbidden to allow pilgrims safe travel to Mecca. The name suggests “sitting still”, a time of peace and preparation.

Key Virtues: As a sacred month, acts of worship carry greater reward, and sins are considered more serious. The month marks the beginning of the Hajj season — the sacred pilgrimage to Mecca that every Muslim who is able is required to perform at least once in a lifetime.

Recommended Practices: Increase worship and good deeds. Those planning to perform Hajj make final preparations. For non-pilgrims, increase in charity, fasting, and supplication (du’a) as the sacred month approaches its peak.

12. Dhu al-Hijjah (ذُو الحِجَّة)

Meaning: “The Month of the Pilgrimage”

Dhu al-Hijjah is the final month of the Islamic year and arguably the most sacred. It is the month of Hajj, the annual pilgrimage to Mecca, which takes place on the 8th through 13th of this month. It is also the fourth and final sacred month.

Key Virtues: The first ten days of Dhu al-Hijjah are described by the Prophet as the best days of the year for worship — even surpassing the last ten nights of Ramadan in their value for good deeds (though Laylat al-Qadr itself remains unparalleled). The 10th of Dhu al-Hijjah is Eid al-Adha (“the Festival of Sacrifice”), commemorating Prophet Ibrahim’s (Abraham’s) willingness to sacrifice his son in obedience to God.

Recommended Practices: For those not performing Hajj: fast on the first nine days (especially the Day of Arafah, the 9th, which expiates sins of the previous and coming year), increase dhikr and takbir (glorification of God), and perform the Qurbani (animal sacrifice) on Eid al-Adha. The meat is shared with family, neighbors, and those in need.

Conclusion

The Islamic lunar calendar is far more than a scheduling tool, it is a living spiritual framework that organizes Muslim life around cycles of devotion, reflection, celebration, and renewal. From the sacred solemnity of Muharram to the joyful sacrifice of Dhu al-Hijjah, each month invites Muslims into a deeper relationship with their faith, their community, and their Creator.

As Muharram begins and a new Hijri year opens, the Muslim world looks ahead for not just to twelve months of time, but to twelve months of intention.
