Whether you're fasting for the first time or seeking deeper understanding, this covers everything you need to know about the science and practice of Ramadan fasting.

When Does Ramadan Begin and End?

Moon Sighting Determines Dates

Ramadan 2026 (1447 AH) is expected to begin around February 28 - March 1, 2026, depending on the hilal (new moon) sighting.

How It Works:

Local moon-sighting committees observe the crescent moon after sunset on the 29th of Sha'ban
If sighted → Ramadan Day 1 begins at Fajr the next morning
If not sighted → Complete 30 days of Sha'ban, then Ramadan starts

Expected End: Around March 29-30, 2026 (29 or 30 days total)

Chennai, India Timing (Approximate):

Ramadan Start: Feb 28, 2026 (Saturday) - Fajr ~5:45 AM IST
Ramadan End: March 29, 2026 (Sunday) - Eid ~6:15 AM IST
Daily Fast: ~12-13 hours (Fajr to Maghrib)

Pro Tip: Use Al Quran Multilingual prayer times feature for exact local timings once Ramadan is confirmed.

When Was Ramadan Fasting Started - History

Revealed 23 Years After Hijrah

Ramadan fasting was obligated in the 2nd year of Hijrah (624 CE) during the month of Sha'ban, making it approximately 18 months after the Prophet Muhammad ﷺ migrated to Madinah.

Reference from Quran Verses

Primary Revelation - Surah Al-Baqarah (2:183-185): https://alquranjino.online/book/ara_quransimple/2/183

"يَا أَيُّهَا الَّذِينَ آمَنُوا كُتِبَ عَلَيْكُمُ الصِّيَامُ كَمَا كُتِبَ عَلَى الَّذِينَ مِنْ قَبْلِكُمْ لَعَلَّكُمْ تَتَّقُونَ"

"O you who have believed, decreed upon you is fasting as it was decreed upon those before you that you may become righteous." [2:183]

Key Points from These Verses:

Fasting is NOT new - Prescribed to previous nations (Jews, Christians)
Purpose: Develop Taqwa (God-consciousness/self-restraint)
Duration: From dawn (Fajr) until nightfall (Maghrib)
Exceptions: Travelers, sick, pregnant women (with conditions) https://alquranjino.online/book/ara_quransimple/2/184
Ease, not hardship: Allah wants ease https://alquranjino.online/book/ara_quransimple/2/185

First Ramadan (2 AH/624 CE):

Muslims fasted for the first time during the Battle of Badr preparation
Combined fasting with military training—showing fasting enhances focus, not weakens it

Eat Suhoor until 10-15 minutes before Fajr:
