Ramadan 2027 in Kolkata, India

Sehri and Iftar in Kolkata

For Kolkata, the evening fast opens at local sunset, shown as 5:03 pm today. The pre-dawn cutoff is calculated separately from the Fajr setting; sunrise is not used as the start of the fast. The page uses Kolkata’s coordinates (22.57, 88.36) and the Asia/Kolkata time zone.

Sunrise-to-sunset daylight in Kolkata lasts 11 hours 26 minutes today. Across the June and December solstices that daylight span differs by about 2 hours 46 minutes at this latitude. That helps explain why Ramadan feels very different when the lunar month returns in another season, but it should not be read as the fasting duration because Fajr occurs before sunrise.

Solar noon in Kolkata is 11:20 am today, about 40 minutes before 12:00 on the local clock. That offset is one reason sunset can look unusually early or late when compared with another city that keeps the same time zone.

For comparison, sunset in Mumbai is 6:09 pm today, 65 minutes later than in Kolkata. Travellers should therefore switch to the timetable for the place where they are actually observing the fast rather than carrying one city’s times across India.

This timetable uses the Karachi prayer calculation setting. The calculation notes explain how the site handles Fajr, Isha and unusual daylight conditions, so that general methodology is not repeated on every location page.
