Kolkata panchang — local sunrise, tithi and rahu kaal
Kolkata panchang is an eastern-India clock: earlier sunrises than Mumbai, a strong Bengali calendar overlay, and festival seasons (especially Sharadiya) that demand accurate tithi.
- Coordinates
- 22.57° N, 88.36° E
- Typical sunrise
- about 4:50 AM in June and after 6:20 AM in December
- Calendar note
- Bengali calendar month names (Boishakh, Asharh, and so on) overlay the same lunar tithi. Durga Puja dates are tithi-critical and must be checked for the current year, not copied from memory.
Kolkata sits far east in the IST zone, so the sun is up while western cities are still dark. Brahma muhurta and office-start rahu kaal therefore look “early” to someone used to Gujarat or Maharashtra timings. That is geography.
Durga Puja, Kali Puja, Saraswati Puja and Poila Boishakh planning fails when people use a North Indian purnimanta discussion as if it were a Bengali almanac. Read today’s tithi on the Kolkata page, then confirm your barowari or family custom.
Seasonal day length at 22.5° N is noticeable: monsoon dawns are early; winter mornings start later. Recheck brahma muhurta when the season changes rather than keeping last quarter’s alarm.
Tithi.live supports Bengali UI labels. The Kolkata coordinates stay fixed; only the language of the chrome changes.
Practical tips for Kolkata
- For Puja holidays, verify tithi the evening before — the civil date on a school notice can lag the lunar day.
- Do not apply a Delhi rahu kaal to a Howrah or Salt Lake ceremony.
- Amavasya tarpan by the Hooghly is sunrise-linked; use this page’s sunrise, not a generic IST guess.
