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 put it roughly nine-and-a-half hours behind San Francisco and in lockstep with 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

- What unusual time offset is shared by Patna and most of India?
- India Standard Time runs at UTC+5:30, a half-hour offset matched by very few countries, making Patna one of the world's minority zones with the quarter-past offset.
- Why does Patna not observe daylight saving?
- India abolished seasonal clock changes in 1945; Patna's clocks have stayed steady year-round, simplifying coordination with partners abroad.
- How is daylight's start consistent throughout the year?
- Around 25.5°N latitude, Patna's sunrise ranges between ~5:00 in winter and ~6:35 in summer, so the 12 PM lunch hour always falls under bright morning sun.
- Which foreign cities share roughly the same working hours with Patna?
- Business hours in Patna overlap heavily with Colombo, Rangoon, Dhaka, and Kathmandu, all within UTC+5:30 or UTC+6, easing intra-South Asia coordination.
- Why are the first and last hours of Patna's workday useful for global teams?
- The 8 AM start in Patna hits at 10:30 PM the prior evening in California and the already-busy hours of Sydney and Auckland, letting eastern-hemisphere planners catch Patna just as western-hemisphere teammates log off.
- 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?
- PM hours 1–3 in Patna align with about 7:30–9:30 AM in the UK and 8:30–10:30 AM in continental Europe, making late afternoons peak windows for calls with Berlin, London, and Paris.
- Why is Patna's timezone history notable?
- In 1947 India adopted UTC+5:30 nationally, ending variations seen during the Raj and cementing a single time across Patna and the entire subcontinent despite its 2,500 km east-west span.
