How this Hijri date converter works
With The tool above You can convert both directions. Gregorian to Hijri for figuring out the Islamic date of a birthday, anniversary, or upcoming event. Hijri to Gregorian if you’ve been told “the nikah is on 12 Rabi al-Awwal” and you need to know which day to book leave.
The conversion runs the moment you change the date or switch modes. No submit button needed for re-conversion, just edit the input.
Why Indian Hijri dates differ from Saudi Arabia by 1 day
Saudi Arabia uses the Umm al-Qura calendar, which is calculated astronomically. The new month starts based on the conjunction, not the actual moon sighting. So a date on a Saudi calendar might say it’s the 1st of Ramadan when the moon hasn’t been physically sighted in India yet.
India follows local moon sighting (rooyat-e-hilal). The Hilal Committee in your region confirms the moon visually before declaring the new month. This usually puts India 1 day behind Saudi Arabia.
For diaspora users (UK, US, Canada), check what your local Islamic authority follows. Some communities go with Saudi, some go with their own sighting, some follow the country of origin. The math is the same, the policy is what differs.
Common uses for the converter
Birthdays and anniversaries in the Islamic calendar. A lot of families want to mark the Hijri date a child was born, not just the Gregorian one. Convert once, write it down, you have it for life.
Wedding and event planning. Islamic invitations often list both dates. If someone tells you the nikah is 15 Shawwal 1447, you need to know that’s around April 2026 to book tickets.
Death anniversaries (barsi/urs). Many families observe these on the Hijri date, which drifts 11 days earlier each Gregorian year. The converter saves you from re-calculating every year.
Fasting and worship planning. The 13th, 14th, and 15th of every Hijri month (Ayyam al-Beed) are sunnah fasting days. The 9th and 10th of Muharram (Ashura). The 15th of Shaban. These all move in the Gregorian calendar, so a quick check before each month helps.
Document verification. Old Indian Muslim records, waqf documents, family genealogies, and some Urdu newspapers print Hijri dates. The Hijri to Gregorian mode is built for exactly this.
Understanding the 12 Hijri months
The Islamic calendar has 12 months, alternating roughly between 29 and 30 days. Total year length is about 354 days, which is why Islamic dates shift backward against the Gregorian calendar.
Here’s what each month means and when it matters:
Muharram — sacred month. Ashura falls on the 10th.
Safar — historically considered a difficult month in some cultures, though there’s no Islamic basis for this.
Rabi al-Awwal — the month of the Prophet’s (SAW) birth and passing. 12th Rabi al-Awwal is observed widely in the subcontinent.
Rabi al-Thani — also called Rabi al-Akhir.
Jumada al-Awwal — first of the two Jumada months.
Jumada al-Thani — also called Jumada al-Akhir.
Rajab — sacred month. 27th Rajab is when many observe Shab-e-Meraj.
Shaban — the month before Ramadan. 15th Shaban is Shab-e-Barat.
Ramadan — the month of fasting. Laylatul Qadr in the last 10 nights.
Shawwal — Eid al-Fitr on the 1st. 6 fasts of Shawwal are sunnah.
Dhul-Qadah — sacred month, the month before Hajj.
Dhul-Hijjah — Hajj season. Eid al-Adha on the 10th. First 10 days are highly virtuous.
How accurate is this converter?
For dates from 1300 AH to 1600 AH (roughly 1882 CE to 2178 CE), The 1-day India adjustment is applied consistently.
A caveat worth being honest about: any date converter is doing astronomical calculation, not actual moon sighting. So if a particular year’s Ramadan started a day late in India because of cloud cover or a contested sighting, no calculator can predict that retroactively. For current and future months, treat the converter as an estimate that’s accurate within a day.
For verifying past dates, especially anything more than 30 years old, cross-check with a printed Islamic calendar from that year if you need legal-grade accuracy (waqf disputes, inheritance cases, court documents).
Frequently asked questions
Q: Why does the date here differ from my phone’s Islamic calendar app?
Your phone app likely defaults to Saudi Arabia or Umm al-Qura without correction. This converter applies the India 1-day offset. Both are technically correct for their respective regions.
Q: Can I convert dates before 1300 AH?
The tool accepts years from 1300 to 1600. For older dates, the API’s reliability drops because lunar tables become less precise the further back you go.
Q: Is the Hijri date the same as the Islamic date in Urdu/Hindi calendars?
Yes. “Hijri date” and “Islamic date” are the same thing. In Hindi/Urdu newspapers, you’ll see it written as “Hijri tareekh” or “Islami tareekh.” The actual numbers are identical.
Q: How is this different from chandkitarikh.in’s homepage date?
The homepage shows you today’s Hijri date for India. This converter lets you check any date, past or future, in either direction.
A note on moon sighting in India
Hijri dates in India aren’t a math problem, they’re a sighting decision. The Markazi Ruyat-e-Hilal committees in Hyderabad, Mumbai, Lucknow, and other cities meet on the 29th of each Hijri month after Maghrib. If the moon is sighted, the next day is the 1st of the new month. If not, the current month gets a 30th day, and the new month starts the day after.
This is why two adjacent countries can be on different Hijri dates. Saudi sees the moon (or calculates it), India waits for local sighting. The converter you used above is calibrated to the India convention.
For real-time sighting announcements during Ramadan, Shawwal, and Dhul-Hijjah, follow the official channels of your local Hilal Committee. No calculator replaces that.
