About Patna time
Patna keeps one clock.
Patna, one of India's oldest continuously inhabited cities in the country's eastern heartland, follows India Standard Time five and a half hours ahead of UTC. That puts it 12 and a half hours ahead of San Francisco (13 and a half when California is on standard time) and on the same clock as the tech hubs of Bangalore and Hyderabad, so mornings here—often misty along the Ganga—overlap neatly with late-evening work on North America's West Coast, making early calls with US teams feel almost second nature.

Frequently asked questions
Common questions about Patna's time zone, daylight saving rules, and scheduling across it. Can't find what you need? Email [email protected].
- What unusual time offset is shared by Patna and the rest of India?
- India Standard Time runs at UTC+5:30, a half-hour offset that only Sri Lanka shares.
- Why does Patna not observe daylight saving?
- India has never used seasonal daylight saving. Its last clock change was in October 1945, when wartime time (UTC+6:30) ended, and Patna has stayed on UTC+5:30 all year since.
- Which foreign cities share roughly the same working hours with Patna?
- Business hours in Patna overlap heavily with Colombo (same time), Kathmandu (15 minutes ahead), Dhaka (30 minutes ahead) and Yangon (1 hour ahead), easing coordination across South Asia.
- Why are the first and last hours of Patna's workday useful for global teams?
- An 8 AM start in Patna is 7:30 PM the previous evening in California (6:30 PM when California is on standard time) and midday to mid-afternoon in Sydney and Auckland, so the start of Patna's day catches US West Coast teams at the end of theirs.
- Which Indian cities follow the same clock as Patna?
- Kolkata, Bengaluru, Mumbai, and Chennai all follow IST, so internal transfers require no local time conversion for Patna-based staff.
- When do Patna's post-lunch hours overlap with Europe?
- 1–3 PM in Patna is 7:30–9:30 AM in London and 8:30–10:30 AM in Berlin and Paris during European winter, and an hour later in each during European summer time, so Patna's afternoons are the best window for calls with Europe.
- Why is Patna's timezone history notable?
- India Standard Time (UTC+5:30) was introduced in 1906, and after independence in 1947 it became the single time across the whole country, replacing the separate Calcutta and Bombay local times, despite India's roughly 2,900 km east-west span.
