Eid ul-Fitr & Eid ul-Adha Date Checker | 100-Year Verified Lunar Calendar (1401–1500 AH)

Every year, the same question echoes across Pakistan and India: “Eid kab hai?” (When is Eid?) — and every year, the Ruet-e-Hilal Committee, moon sighting debates, and last-minute announcements create confusion for millions.

But what if there was a 100-year calendar that has been accurately predicting Eid dates since 1981 — and hasn’t been wrong even once?

That’s exactly what this verified lunar calendar does. Covering 1401 AH to 1500 AH (1981 to 2077), it maps out both Eid ul-Fitr and Eid ul-Adha dates with remarkable precision — and we’ve turned it into a free, interactive app so anyone can check it instantly.

📜 What is the 100-Year Lunar Calendar?

The 100-Year Lunar Calendar is a chart titled “پاک و ہند میں عید الفطر از 1401 ہجری تا 1500 ہجری کس دن ہوگی” (When will Eid ul-Fitr fall in Pakistan and India from 1401 AH to 1500 AH). It has been circulating in Islamic publications for decades and recently went viral on social media.

What makes it special? Every single prediction from 1981 to 2025 has been verified as accurate. The calendar lists the exact Gregorian date and day of the week for Eid ul-Fitr for each Hijri year — and it has matched the officially observed dates in Pakistan each time.

🌙 2026 — A Historically Significant Year

This year (1447 AH / 2026) is particularly notable for several reasons:

SUPARCO (Pakistan Space & Upper Atmosphere Research Commission) confirmed that the Shawwal crescent moon’s visibility on March 19 was very low, meaning Ramadan completed 30 fasts and Eid ul-Fitr fell on Saturday, March 21 — exactly as predicted by the 100-year calendar.

Additionally, the government announced a 4-day holiday weekend: Eid on Friday-Saturday (March 20-21), Sunday (weekly off), and Pakistan Day on Monday (March 23).

🔬 How Does the 100-Year Calendar Work?

The Islamic (Hijri) calendar is a lunar calendar with 354 or 355 days per year — about 10-11 days shorter than the solar Gregorian calendar. This means Islamic events like Eid shift backward through the Gregorian calendar each year, cycling through all seasons over approximately 33 years.

The calendar uses astronomical calculations based on:

• Lunar cycle length: Average synodic month = 29.53059 days
• Moon age at sunset: Crescent needs to be 15-20+ hours old to be visible
• Pakistan-specific patterns: Accounting for the country’s geographic latitude and coastal belt moonset timing
• Historical pattern matching: Cross-referencing with decades of actual Ruet-e-Hilal Committee decisions

The result is a table that can predict — with high accuracy — exactly when each Eid will fall, years and even decades in advance.
