About Howrah time
Howrah keeps one clock.
Howrah hums alongside Kolkata on the banks of the Hooghly River, with a rhythm set to Indian Standard Time—where tea stalls open early, the Howrah Station buzzes all day, and daylight hours align with the extended workday that starts before nine and stretches into the evening. IST is fixed, at UTC+5:30, so Howrah’s offices coordinate seamlessly with the rest of India, but you’ll notice that across the Atlantic and Europe it means the day begins in their nighttime, not their workday.

Frequently asked questions
Common questions about Howrah's time zone, daylight saving rules, and scheduling across it. Can't find what you need? Email [email protected].
- Why does India use a :30 and not :00 or :45 offset for IST?
- IST is based on the 82.5°E meridian in central India, which lies exactly 5.5 hours ahead of Greenwich. It was introduced in 1906, replacing earlier local times such as Madras Time (UTC+5:21:10).
- Is IST related to British-era time zones?
- Yes. Before independence, British India used Madras Time (UTC+5:21) among others. IST’s half-hour offset was standardized only in the 20th century.
- How does Howrah’s daylight compare to IST?
- Howrah lies east of IST’s reference meridian (82.5°E), so the sun rises and sets earlier than the clock suggests: solar noon falls between about 11:20 and 11:50, and sunrise ranges from about 4:50 AM in June to 6:20 AM in winter.
- Is IST the same in every city in India?
- Yes. India is one nation under one time zone; IST binds Delhi, Howrah, Mumbai, and Thiruvananthapuram into shared hours.
- What’s IST’s UTC offset if my system shows a different abbreviation?
- IST is always UTC+5:30 in India. If you see "IST" elsewhere, it might mean Israel Standard Time or Irish Standard Time, which are completely different offsets.
- Did India ever use daylight saving time?
- Only during World War II, when clocks ran an hour ahead at UTC+6:30 for most of the period from October 1941 to October 1945; since then India has stayed on IST without daylight saving time.
