Prayer Time Orientation: Muslims in Kolkata observe the five daily prayers—Fajr, Dhuhr, Asr, Maghrib, and Isha—according to the city's local timezone, Asia/Kolkata.

The Qibla direction for prayer is oriented towards Mecca, with the city's specific bearing and distance to the Kaaba guiding worshippers.
