The twelve Hijri months: names, meanings and what they mark

The twelve Hijri months are Muharram, Safar, Rabi al-Awwal, Rabi al-Thani, Jumada al-Ula, Jumada al-Akhirah, Rajab, Sha‘ban, Ramadan, Shawwal, Dhu al-Qa‘dah and Dhu al-Hijjah. Their names preserve older Arabic language and history; their religious significance comes from evidence about particular months and occasions, rather than a hidden meaning assigned to every name. Dar al-Ifta, month sequence and calendar history.

Knowing the sequence changes how a familiar announcement sounds. Eid al-Fitr means Shawwal has begun. Hajj takes place near the end of the year, rather than in its middle. Muharram follows Dhu al-Hijjah, so the sacred-month sequence crosses the year boundary.

This companion to our Islamic calendar overview focuses on the months themselves. It distinguishes linguistic explanations, established worship and commemorations whose dates or observance differ between traditions.

Before reading the names: seasons and sacred months

Some month names recall spring, dryness or heat. Those associations do not predict today’s weather: lunar months move through the solar seasons. The Turkish Diyanet Foundation’s scholarly encyclopedia explicitly makes that distinction in discussing Rabi al-Awwal. Historical naming explanations sometimes vary, so a possible derivation should not be presented as an independently proven event. TDV Encyclopedia of Islam, Rabi al-Awwal.

The Quran identifies twelve months, four sacred. A report in Sahih al-Bukhari names Muharram, Rajab, Dhu al-Qa‘dah and Dhu al-Hijjah. Ramadan has explicit Quranic importance but is not one of that designated group of four. Quran 9:36; Sahih al-Bukhari 3197. See our guide to the four sacred months for the distinction in greater depth.

1. Muharram: a sacred beginning

Muharram’s name is commonly rendered “forbidden,” connected with its protected status. It begins the Hijri year. A change of year number should not be confused with the anniversary date of the Prophet Muhammad’s ﷺ migration itself. TDV Encyclopedia of Islam, Muharram; Dar al-Ifta, calendar history.

Ashura is the tenth. Sunni hadith sources connect fasting on it with remembrance of Allah’s rescue of Moses and his people. For Shia Muslims, the date is especially associated with mourning Imam Husayn and the martyrs of Karbala. These meanings need to be stated distinctly. Sahih al-Bukhari 2004; Sistani’s office, mourning and remembrance. Our Muharram and Ashura guide explains both contexts.

2. Safar: a name without a curse

TDV records several explanations of Safar’s name, including emptiness associated with households left behind when people departed. That is a historical explanation, not evidence that the month brings misfortune. TDV, Safar.

Scholars have interpreted the hadith’s reference to Safar in more than one way. TDV nevertheless describes beliefs that marriages in Safar fail or undertakings end badly as baseless. The month should not become a reason to fear an otherwise permissible wedding, journey or ordinary responsibility. A date alone does not establish a prediction about someone’s future. Sahih al-Bukhari 5757; TDV, Safar.

3. Rabi al-Awwal: the first Rabi

Often translated as “the first spring,” the name belongs to a pair. Rabi also had wider seasonal associations in older Arabic usage. It does not mean the month must arrive during spring in either hemisphere. TDV, Rabi al-Awwal.

Many communities associate this month with Mawlid, remembering the Prophet’s ﷺ birth. Historical reports differ about the birth date, and scholars also differ over annual commemoration. Our article on Mawlid explains contrasting scholarly positions without making attendance a test of love. TDV, Mawlid and reported birth dates.

4. Rabi al-Thani: the second Rabi

Rabi al-Thani is also called Rabi al-Akhir: the second, or latter, Rabi. These are alternative names for the fourth month, not two additional months. The same caution about seasonal language applies to both members of the pair. TDV, Rabi al-Awwal and the paired names.

Read Rabi al-Thani as a month name in that sequence. A calendar heading is not, by itself, evidence that a particular ceremony is prescribed. If an event is listed, check its stated source and the tradition it belongs to.

5. Jumada al-Ula: the first Jumada

Jumada al-Ula, also written Jumada al-Awwal, is the fifth month. The TDV Encyclopedia of Islam explains Jumada through cold and dryness, recording that the naming was associated with such conditions. They should be understood as naming traditions, rather than a forecast or a command to perform a particular act of worship. TDV Encyclopedia of Islam, the two Jumada months.

The practical detail is the pair: al-Ula identifies the first Jumada. When comparing calendars, check the month number as well as an unfamiliar spelling.

6. Jumada al-Akhirah: the second Jumada

The sixth month is Jumada al-Akhirah, also called Jumada al-Thani or al-Thaniyah. It shares the naming history of the preceding month; “second” and “latter” distinguish its place. TDV Encyclopedia of Islam, Jumada names and order.

Spellings such as Jumada, Jumādā and regional pronunciations can look quite different in English. A reader unfamiliar with Arabic should not mistake a transliteration difference for a disagreement over the calendar’s order.

7. Rajab: honour and a sacred month

Rajab’s name is connected with honour and reverence. It is the sacred month standing apart from the three consecutive sacred months around the year boundary. TDV, Rajab; Sahih al-Bukhari 3197.

Some calendars associate 27 Rajab with Isra and Mi‘raj; historical dating and devotional practices need separate assessment. Twelver Shia calendars also identify that date as Mab‘ath, the beginning of the Prophet’s ﷺ mission: Sistani’s fasting guidance explicitly names it that way. Those entries should not be silently treated as descriptions of the same event. TDV, Rajab; Sistani, recommended fasts.

8. Sha‘ban: between Rajab and Ramadan

Sha‘ban’s name is connected with dispersing or dividing into groups; explanations relate it to older Arab activities. Its position before Ramadan makes it a natural time to prepare, but the month has its own evidence concerning worship. TDV, Sha‘ban.

Aisha reports that the Prophet ﷺ fasted more in Sha‘ban than in other months outside Ramadan. That supports a discussion of fasting across the month; it is not, by itself, evidence for every practice attached to its fifteenth night. Sahih al-Bukhari 1969.

9. Ramadan: fasting and revelation

Ramadan’s name is associated with intense heat, although Ramadan now reaches every season. Its religious standing is explicit: the Quran identifies it as the month of revelation and prescribes fasting, with provisions for illness and travel. The name’s linguistic roots do not create the obligation; the revealed instruction does. TDV, Ramadan; Quran 2:185.

Laylat al-Qadr belongs to Ramadan. Sunni reports direct believers to seek it in the odd nights of the last ten; a highlighted twenty-seventh night is not a universal proof of its exact occurrence. Quran 97; Sahih al-Bukhari 2017. See the last ten nights.

Twelver Shia guidance gives particular attention to the nineteenth, twenty-first and twenty-third nights, as IMAM-US explains. These emphases should be identified rather than merged into one universal calendar rule. IMAM-US, Islamic Laws of Fasting, “The Nights of Destiny”.

10. Shawwal: Eid and what follows

Shawwal’s name derives from a root associated with rising or lifting; TDV records different explanations of its historical naming. Its first day is Eid al-Fitr, ending Ramadan’s fasts. TDV, Shawwal.

A Sunni report in Sahih Muslim commends six fasts in Shawwal after Ramadan. These are distinct from fasting Ramadan and from the Eid day, when fasting is prohibited. Questions about outstanding obligatory fasts and combining intentions require the guidance of the school you follow. Sahih Muslim 1164a; Sahih al-Bukhari 1990.

11. Dhu al-Qa‘dah: a month of refraining

The name is traditionally explained through sitting or refraining, associated with an older cessation of hostilities. It is one of the four sacred months and immediately precedes the month of Hajj. TDV, Dhu al-Qa‘dah.

The historical name should not be turned into an instruction to stop ordinary work. Nor does the fact that the month falls between the two Eids make a marriage during it unlucky; TDV specifically notes that such a belief lacks a religious basis. TDV, Dhu al-Qa‘dah.

12. Dhu al-Hijjah: the month of pilgrimage

Dhu al-Hijjah means the month of Hajj. It closes the year and is also sacred. Arafah is the ninth; Eid al-Adha is the tenth. These dates belong to a sequence of pilgrimage rites and worship, rather than an interchangeable “Hajj week.” TDV, Dhu al-Hijjah; Sistani, fasting date notes.

For Twelver Shia Muslims, 18 Dhu al-Hijjah is also Eid al-Ghadir; Sistani’s guidance explicitly identifies that date. A globally useful calendar can name a tradition’s observance without suggesting all traditions understand or mark it identically. Sistani, recommended fasts. See Arafah, Eid and Dhu al-Hijjah for the existing detailed guide.

Use the sequence without assuming one worldwide date

Month names tell you the order. They do not settle which Gregorian day your community recognises as the first. The guide to differing Eid dates explains the sighting and authority questions behind that difference.

When saving an occasion, include the Hijri date, the Gregorian date used by the relevant community, and the preceding evening where needed. Then a familiar name becomes something you can understand and use, while its historical or devotional meaning remains accurately described.
