Frequently Asked Questions
What is UTC?
UTC (Coordinated Universal Time) is the global time standard. All time zones are defined as offsets from UTC. IST (India Standard Time) is UTC+5:30, meaning India is 5 hours and 30 minutes ahead of UTC.
Why is India UTC+5:30?
Indian Standard Time is set on the 82.5° E meridian near Mirzapur, which sits roughly in the middle of the country — 5 hours 30 minutes ahead of UTC. IST was introduced on 1 January 1906 and became the official time for the whole country after independence in 1947.
What is Daylight Saving Time?
Many countries in North America and Europe move their clocks forward one hour in summer. India, China, Japan and most of Asia don't. That's why the gap between India and the US or UK changes by an hour during the year — this converter handles it automatically for the date you pick.
What is the best time for India–US meetings?
Early evening in India overlaps with the US East Coast morning. From November to March, 6:30–8:30 PM IST is 8:00–10:00 AM in New York; from March to November (US daylight saving), the same IST window is 9:00–11:00 AM in New York. Use the converter above to check any exact date.
How do I convert IST to EST or ET?
India is 10 hours 30 minutes ahead of New York from November to March, and 9 hours 30 minutes ahead during US daylight saving (March to November). Choose India as the From zone, enter your time, and see New York's time instantly.
How do I convert IST to PST or PT?
India is 13 hours 30 minutes ahead of Los Angeles in winter and 12 hours 30 minutes ahead during US daylight saving. Pick India as the From zone to see the exact Los Angeles time for your date.
What is the time difference between India and the UK?
India is 5 hours 30 minutes ahead of the UK in winter (GMT) and 4 hours 30 minutes ahead during British Summer Time (late March to late October).
Does India have Daylight Saving Time?
No. India uses Indian Standard Time (UTC+5:30) all year round, so the time difference with countries that use daylight saving changes during the year.
What is the difference between GMT and UTC?
For everyday use they show the same time. UTC is the precise international time standard; GMT is the time zone used in the UK in winter. In summer the UK switches to BST (UTC+1).
How do I schedule a meeting across time zones?
Pick a time in one zone, check it here against every attendee's city, and look for an overlap within working hours. Share the time in each attendee's zone, or send a calendar invite, which converts automatically.
Which time zones does this converter support?
23 cities across India, the US, Canada, Brazil, the UK, Europe, Africa, the Middle East, South and East Asia, Australia and New Zealand. Daylight saving is applied automatically for the date you enter.
What time is it in the US when it's 9 AM in India?
At 9 AM IST it's the previous evening in the US — 10:30 PM in New York in winter (11:30 PM during US daylight saving). Enter your exact date above to check.
