Gregorian Months and Their Hijri Equivalents in 2026

The Gregorian Months and Their Days in Order

January 31 days, February 28 days (29 in a leap year), March 31, April 30, May 31, June 30, July 31, August 31, September 30, October 31, November 30, December 31. The total is 365 days in a regular year and 366 in a leap year.

An easy way to remember the day counts: the knuckle rule; make a fist and count the months on the knuckles and dips starting with January on a knuckle. Months landing on a raised knuckle have 31 days, and those in a dip have 30 (except exceptional February). Another way: the odd months through July have 31 days except February, then the rule reverses after July.

The leap year: a year divisible by 4 (like 2024 and 2028) has February with 29 days, except century years not divisible by 400 (1900 was not a leap year, while 2000 was). The reason for leap years is that the true solar year is about 365.25 days, so a day is added every 4 years to compensate.

The Hijri Months, Their Days, and Why the Year Is Shorter

The Hijri months in order: Muharram, Safar, Rabi al-Awwal, Rabi al-Thani, Jumada al-Ula, Jumada al-Akhirah, Rajab, Sha'ban, Ramadan, Shawwal, Dhul-Qadah, Dhul-Hijjah. Each month is 29 or 30 days depending on confirmed moon sighting, and the Hijri year is 354 or 355 days, about 11 days shorter than the Gregorian.

The reason for the difference: the Hijri calendar is lunar, based on the moon's orbit around the earth (29.5 days x 12 = 354 days), while the Gregorian is solar, based on the earth's orbit around the sun (365.25 days). Because of this difference, Hijri occasions like Ramadan and Hajj move through the Gregorian seasons, completing a full cycle about every 33 years; whoever fasted Ramadan in summer will fast it in winter years later.

The start of the Hijri calendar: the Prophet's migration (Hijrah) from Mecca to Medina, peace be upon him, adopted by Caliph Umar ibn al-Khattab, may Allah be pleased with him. The sacred months are four: Dhul-Qadah, Dhul-Hijjah, Muharram, and Rajab, months in which sanctities are magnified.

How to Convert Between the Calendars: Practical Methods

The most accurate method: use the conversion calculator on our site; it gives you the date in both calendars instantly. The rough manual method for the year: Hijri year = (Gregorian year - 622) x 33 / 32. Example: 2026 - 622 = 1404; 1404 x 33 / 32 = 1447.6, meaning we are in 1447-1448 AH.

Converting a day and month precisely by hand needs lengthy conversion tables and is complicated, so the calculator is the practical answer. Always remember that calculated conversion may differ by a day or two from the official moon-sighting calendar, so do not base day-precise appointments on it, like a scheduled cesarean date; confirm with the hospital.

A quick mental trick: every 33 Gregorian years roughly equal 34 Hijri years (because the Hijri is shorter). So if you know that 2026 corresponds to 1447 AH, know that the gap slowly grows over time.

An Approximate Table of Month Correspondence in 2026-2027

Caution: this table is approximate (plus or minus two days) because Hijri month starts depend on actual moon sighting and are announced officially. Do not rely on it for precise appointments; use it for general understanding and organizing your journal.

Why Does This Matter for Tracking Your Pregnancy?

If you track your pregnancy in Hijri (due date, pregnancy weeks, visit appointments) while ultrasound reports and private-hospital appointments are in Gregorian, mastering conversion saves you from the confusion that could make you miss an important screening or show up on the wrong day.

The practical solution: keep both dates together in your pregnancy journal. Example: due date 12 Jumada al-Akhirah 1448 AH (approximately 20 November 2026). And the week 28 visit on 12 Dhul-Qadah 1447 AH (approximately 30 April 2026). Write both dates side by side for every appointment. The Hijri pregnancy calculator on our site shows you both dates automatically, saving you the trouble.

For official appointments (government hospitals and departments), rely on the officially announced Hijri date, and for private appointments and medical reports you may find the Gregorian; having both dates together in your journal saves you from calculating every time.
