Date converter guide — Hijri & Gregorian | Itqan

Need the Gregorian equivalent of your Hijri birth date, or the reverse for Ramadan planning, a government form, or a contract clause? The date converter on Itqan converts between Hijri and Gregorian calendars instantly — with day names in both languages and one-click copy. This guide explains how the two calendars differ, walks through four everyday scenarios, and covers accuracy, moon sighting, and common slip-ups.

What the date converter does

The Itqan date converter translates a single date from the Islamic Hijri (lunar) calendar to the Gregorian (solar) calendar, or the other way around. You pick a day, month, and year in one system; the tool returns the matching date in both systems at once.

That matters because Hijri months drift through the Gregorian year — Ramadan does not land on the same Gregorian dates every year, and a Hijri birthday never lines up with a fixed Gregorian day without calculation. Spreadsheets and mental arithmetic break down quickly; a dedicated converter gives a consistent answer in seconds.

Unlike the age calculator (which measures elapsed time between two dates) or the invoice calculator (line items and totals), this tool answers one question: what is this date in the other calendar?

Two calendars, one lifelong drift

The Hijri (lunar) calendar

The Hijri calendar follows the moon’s phases. A Hijri year is roughly 354 or 355 days — about 11 days shorter than a Gregorian year, so the same Hijri date drifts earlier through the solar calendar over time. Hijri dates appear on Gulf IDs, certificates, court filings, and religious schedules. Month names — Muharram, Safar, Ramadan — are not January through December.

The Gregorian (solar) calendar

The Gregorian calendar tracks Earth’s orbit. It is the global standard for passports, contracts, and software defaults. 1 Ramadan 1447 AH and 1 March 2026 are not interchangeable labels — they need a conversion algorithm, which this tool provides.

Everyday situations that call for conversion

• Government and banking forms that ask for birth date in one calendar while your documents show the other.
• Religious planning — mapping Hijri months to Gregorian weeks for leave requests, school notices, or community events.
• Legal and business contracts where one party drafts in Gregorian dates and another references Hijri anniversaries or payment milestones.
• Family records — grandparents’ dates in Hijri, children’s school forms in Gregorian.
• Historical and academic work — sources that mix Ottoman, Hijri, and Gregorian dating in the same footnote.

Below we walk through four concrete cases step by step.

Case-by-case walkthroughs

Scheduling Ramadan — from 1 Ramadan to your wall calendar

A mosque committee books a hall for the first taraweeh night and must notify members who think in Gregorian weeks. Open the date converter, choose From Hijri, enter 1 Ramadan 1447, and read the weekday to avoid booking the wrong Friday or Saturday.

Important: Many countries start Ramadan after official moon sighting — the calculated date may differ by one day. Plan with the converter; confirm with your local authority before publishing the final schedule.

Government portal — Hijri on your ID, Gregorian on the form

You are completing an online visa, scholarship, or university application that requires date of birth in DD/MM/YYYY (Gregorian). Your Saudi or Gulf national ID lists 12 Sha'ban 1410 AH, and the portal has no Hijri field.

Select From Hijri, set 12 Sha'ban 1410, click Convert, and copy the Gregorian card into the form. Confirm whether the portal uses DD/MM/YYYY or US-style MM/DD/YYYY before submitting. If the form wants Hijri instead, use From Gregorian and reverse the steps.

Manuscript footnote — placing 892 AH in European archives

A history student cites a chronicle recording an event on 15 Jumada al-Thani 892 AH. The thesis supervisor wants a Gregorian range to cross-reference with fifteenth-century European archives and Ottoman administrative registers.

Enter the Hijri date to place the event in the late fifteenth century Gregorian for cross-checking Ottoman or Mamluk archives. Cite the converter as a baseline; pre-modern sources sometimes rounded months. Reverse the direction from From Gregorian when working from a death certificate to a tombstone inscription.

Lease side letter — when 1 Muharram meets monthly rent

A commercial lease states rent is due on the first day of each Gregorian month, but a side letter grants a rent-free week starting on 1 Muharram each Hijri year. The finance team needs to know when those weeks fall in the current and next Gregorian years to adjust cash-flow forecasts and tenant notices.

Convert 1 Muharram 1447 (and the next Hijri year if needed). Hijri anniversaries shift through the Gregorian calendar, so multi-year deals need fresh conversions each year. The signed contract remains authoritative; the tool supports finance planning, not legal advice.

Step-by-step conversion on Itqan

1. Open the date converter — no registration required.
2. Choose From Hijri if your known date is lunar, or From Gregorian if it is solar.
3. Select day, month, and year from the dropdowns. Hijri months show Arabic names; Gregorian months follow the standard twelve.
4. Click Convert.
5. Review the two result cards — Hijri and Gregorian — each with a full date string and weekday.
6. Click Copy beside the format you need for your form, email, or calendar entry.

On mobile, the same flow works in portrait mode; the dropdowns are touch-friendly for quick checks at a government office or airport counter.

Dual calendar output explained

After conversion, two cards appear side by side (or stacked on narrow screens):

• Hijri card — day number, Arabic month name, year AH, and weekday in Arabic.
• Gregorian card — day, month name, year CE, and weekday in English.

Both calendars always display, even from one input tab, so you can spot mistakes (e.g. a July result when you expected winter) before pasting into a form. The weekday helps schedule hearings and travel around religious holidays.

Math, tables, and moon sighting

Itqan uses established Hijri–Gregorian conversion logic (hijri-date library) aligned with standard tabular calendars — suitable for visas, IDs, and research. Religious month starts may follow moon-sighting announcements and differ by one day; follow local news for fasting and Eid.

Conversion traps to avoid

Mapping Hijri months to Gregorian month numbers

Ramadan is the ninth Hijri month, not “September.” Safar is the second Hijri month and does not correspond to February in length or position. Always confirm you are on the correct input tab before converting.

Swapping day and month on international forms

US forms often use MM/DD/YYYY while Gulf and European forms use DD/MM/YYYY. The converter shows an unambiguous day and month — read the field labels on the portal before pasting.

Ignoring the year

15 Rabi al-Awwal 1446 and 15 Rabi al-Awwal 1447 are a full lunar year apart. A missing digit creates silent errors on legal paperwork.

Assuming Eid matches calculated 1 Shawwal

Community celebrations may follow a different announcement than your personal app. Verify before booking time off.

Before you submit a date

• Confirm which calendar the form requires — look for “AH,” “Hijri,” “ميلادي,” or “Gregorian.”
• Match the From Hijri / From Gregorian tab to the calendar you already know.
• Copy from the correct result card; do not mix the year from one card with the month from the other.
• For religious deadlines, check official moon-sighting news after conversion.
• For contracts, attach both calendar versions in an appendix if parties use different systems.

Practical tips

Save both converted strings when portals repeat the same birth-date question. HR teams can map Hijri public holidays to Gregorian at the start of each Hijri year. Set phone reminders by converting upcoming Hijri anniversaries ahead of time.

FAQ

Summary

Hijri and Gregorian dates measure different astronomical cycles, so conversion belongs in every workflow that touches IDs, religious planning, history, or contracts. Itqan’s date converter shows both calendars and weekday names in one step, with copy buttons for forms and free in-browser use. Plan with the calculated result; for Ramadan and Eid, align with official announcements in your country.
