Bangalore Time Zone: India Standard Time (IST) and UTC+5:30
Bangalore — officially Bengaluru since the Kannada name became the city's official English spelling in 2014 — runs on India Standard Time (IST) at UTC+5:30. The IANA timezone identifier is Asia/Kolkata, the single zone that covers all of India, so Bangalore keeps exactly the same time as Mumbai, Delhi, Chennai, Hyderabad and every other Indian city. India does not observe daylight saving time: IST stays fixed at UTC+5:30 every day of the year, and any seasonal shift in your offset to Bangalore comes from clock changes on your side, not India's.
Bangalore is widely called the Silicon Valley of India. It is the headquarters city of Infosys and Wipro, a major base for Tata Consultancy Services, and hosts large engineering centres for Google, Microsoft, Amazon, Intel, Cisco, SAP and hundreds of global capability centres, alongside one of the world's most active startup ecosystems. That concentration of technology work makes "what time is it in Bangalore?" one of the most practical questions in global software delivery — millions of standups, sprint reviews and support handoffs are scheduled against IST.
The rhythm with US tech companies is well established. When it is 9:00 AM Pacific Standard Time in San Francisco, it is already 10:30 PM in Bangalore — so same-day overlap with the US West Coast is limited to early US mornings, which land in Bangalore's evening (8:00 AM PST is 9:30 PM IST). Many India–US teams instead run morning standups on US East Coast time: 9:00 AM in New York is 7:30 PM in Bangalore during winter (EST) and 6:30 PM during summer (EDT), late in the Indian workday but workable. The reverse handoff is popular too — a 9:00 AM IST meeting in Bangalore is 10:30 PM the previous evening in New York (EST), which is why "follow-the-sun" support models pass work from US evenings into Bangalore mornings.
With the UK and Europe the overlap is far more comfortable. Bangalore is 5 hours 30 minutes ahead of London on GMT and 4 hours 30 minutes ahead during British Summer Time; a 10:00 AM meeting in London is 3:30 PM or 2:30 PM in Bangalore, inside standard office hours for both sides. Central Europe sits one hour closer still. Within Asia, Singapore — a frequent regional counterpart for Bangalore teams — runs 2 hours 30 minutes ahead of IST, so office hours align for most of the day.
Geographically, Bangalore sits at about 12.97°N, 77.59°E on the Deccan Plateau, roughly 900 metres above sea level — the altitude behind its famously mild climate. Its position west of the 82.5°E IST reference meridian means solar noon arrives around 20 minutes after clock noon, and being near the equator, its day length barely changes across the year: sunrise and sunset hold close to 6:00 AM and 6:30 PM IST in every season.
