Frequently Asked Questions

Your browser uses your device's system time zone, which is set in your operating system. You can see yours in the 'Your Local Time' section above in IANA format - for example, Asia/Kolkata for India, America/New_York for US Eastern, Europe/London for UK. This is determined by your OS settings, not your IP address or physical location. If you've recently moved or your clock seems wrong, update the time zone in your device's date and time settings.
UTC (Coordinated Universal Time) is the global time standard. All time zones are expressed as offsets from UTC. UTC+5:30 means 5 hours and 30 minutes ahead of UTC - which is India Standard Time. UTC-5 means 5 hours behind UTC - which is US Eastern Standard Time. The '+' zones are east of the prime meridian (the UK); the '-' zones are west. UTC is essentially the same as Greenwich Mean Time (GMT), though there are technical differences.
India (IST, UTC+5:30) is ahead of the USA. The exact difference depends on the US time zone and the season. New York (EST, UTC-5): India is 10h 30m ahead in winter, 9h 30m during US EDT (summer). Los Angeles (PST, UTC-8): India is 13h 30m ahead in winter, 12h 30m during US PDT. Chicago (CST, UTC-6): India is 11h 30m ahead in winter, 10h 30m during CDT. The difference changes twice a year because the US observes Daylight Saving Time but India does not.
No - India has not observed Daylight Saving Time since 1945. IST (UTC+5:30) is fixed year-round. This simplifies time calculations within India but means the time difference between India and DST-observing countries (USA, UK, EU, Australia) changes twice per year. When the UK springs forward to BST (British Summer Time) in March, the India-UK difference shrinks from 5h 30m to 4h 30m. When the UK falls back in October, the difference returns to 5h 30m. China and Japan also do not observe DST.
The best overlap for India-UK calls is the afternoon in India and morning in the UK. In summer (BST, UTC+1): UK working hours of 9 AM–5 PM = 1:30 PM–9:30 PM IST. Practical overlap: 1:30 PM–6 PM IST = 9 AM–1:30 PM BST. In winter (GMT, UTC+0): 2:30 PM–6 PM IST = 9 AM–11:30 AM GMT. The overlap narrows in UK winter because GMT is 5:30 hours behind IST instead of 4:30.
Nepal is UTC+5:45, making it 15 minutes ahead of India (UTC+5:30) and one of only three quarter-hour time zone offsets in the world (along with Chatham Islands at UTC+12:45 and parts of Australia). Nepal chose this offset to differentiate itself from India - the 15-minute difference was a deliberate choice to maintain national distinctiveness while staying geographically appropriate. The Nepal–India time difference of 15 minutes is one of the smallest international time zone differences in the world.
Countries very close in time to India: Nepal is UTC+5:45 - 15 minutes ahead of IST. Sri Lanka (UTC+5:30) shares exactly the same time as India - IST and SLST (Sri Lanka Standard Time) are identical. Pakistan (UTC+5) is 30 minutes behind India. Bangladesh (UTC+6) is 30 minutes ahead. Maldives (UTC+5) is 30 minutes behind. This makes South Asia one of the most time-zone-fragmented regions in the world, with five different offsets across adjacent small countries.
Use the Compare Zones tab above to see up to 4 cities at once. The general strategy: find the window where all locations are within working hours (8 AM–6 PM). For India + US calls, aim for 6:30–9 PM IST in summer (= 9–11:30 AM EDT). For India + UAE calls, any time from 9 AM–4:30 PM IST works for both. For India + Singapore calls, mornings in India (9 AM–1 PM IST) are afternoons in Singapore (11:30 AM–3:30 PM SGT). If three or more continents are involved, rotate the 'inconvenient' time slot between teams so no single team always takes the early morning or late evening call.

Current Time in City - World Clock Guide, Time Zones & UTC Offsets

Knowing the current local time in another city sounds simple until you need to get it exactly right - for a business call with a client in London, a customer service chat with a US company, or a video call with family in Dubai. This world clock shows live local times updating every second, with full UTC offsets and how far ahead or behind each city is from your local time.

Quick reference - India (IST) vs major hubs: India is UTC+5:30. Dubai (UAE) is UTC+4 - India is 1h 30m ahead. London (GMT) is UTC+0 - India is 5h 30m ahead (4h 30m during UK BST). New York (EST) is UTC-5 - India is 10h 30m ahead. Singapore is UTC+8 - India is 2h 30m behind. Tokyo is UTC+9 - India is 3h 30m behind.

India Standard Time (IST) - Why It's UTC+5:30

India Standard Time is one of the few time zones in the world with a 30-minute offset rather than a whole hour. Most time zones fall on exact hours from UTC - but some, including India (+5:30), Nepal (+5:45), Iran (+3:30), and a handful of others, use half or quarter-hour offsets.

India's 30-minute offset was set to approximate the solar noon midpoint across the subcontinent. The country spans roughly 30 degrees of longitude (roughly 2 hours of sun travel), and UTC+5:30 was chosen as a compromise so solar noon falls reasonably close to 12:00 PM across most populated areas. India uses a single time zone for the entire country despite its geographic width - unlike the US (4 contiguous zones) or Russia (11 zones).

India does not observe Daylight Saving Time and has not done so since 1945. This means IST is always fixed at UTC+5:30, making calculations simpler - but also meaning the time difference between India and countries that do observe DST (USA, UK, EU) changes twice a year.

How Daylight Saving Time Changes the India–US and India–UK Difference

Daylight Saving Time (DST) - called British Summer Time in the UK and referred to as Eastern Daylight Time (EDT), Central Daylight Time (CDT), etc., in the US - advances clocks by 1 hour in spring and reverts in autumn. Since India doesn't adjust, the difference between India and DST-observing countries shifts by 1 hour twice per year:

India vs UK Time Difference

  • Oct–Mar (GMT, UTC+0): India is 5h 30m ahead of UK
  • Mar–Oct (BST, UTC+1): India is 4h 30m ahead of UK
  • UK clocks change last Sunday of March (spring forward) and last Sunday of October (fall back)
  • 12:00 noon in London = 5:30 PM IST in winter, 4:30 PM IST in summer

India vs US East Coast (New York)

  • Nov–Mar (EST, UTC-5): India is 10h 30m ahead
  • Mar–Nov (EDT, UTC-4): India is 9h 30m ahead
  • US clocks change second Sunday of March and first Sunday of November
  • 9:00 AM EST = 7:30 PM IST. 9:00 AM EDT = 6:30 PM IST
  • Best meeting overlap: 8–9 AM New York = 6:30–7:30 PM India (EDT window)

UTC Offsets for Major Cities - Complete Reference

UTC (Coordinated Universal Time) is the reference point for all time zones. Positive offsets are east of UTC, negative offsets are west. Here are the key offsets for cities most commonly searched from India:

  • India (IST) - UTC+5:30. No DST. All Indian cities share this single zone.
  • UAE / Dubai (GST) - UTC+4. No DST. Always 1h 30m behind India.
  • Saudi Arabia (AST) - UTC+3. No DST. Always 2h 30m behind India.
  • Singapore (SST) - UTC+8. No DST. Always 2h 30m ahead of India.
  • Japan / Tokyo (JST) - UTC+9. No DST. Always 3h 30m ahead of India.
  • UK (GMT/BST) - UTC+0 in winter, UTC+1 in summer. 5h 30m/4h 30m behind India.
  • Germany/France/Netherlands (CET/CEST) - UTC+1 in winter, UTC+2 in summer. 4h 30m/3h 30m behind India.
  • New York (EST/EDT) - UTC-5 in winter, UTC-4 in summer. 10h 30m/9h 30m behind India.
  • Los Angeles (PST/PDT) - UTC-8 in winter, UTC-7 in summer. 13h 30m/12h 30m behind India.
  • Sydney (AEST/AEDT) - UTC+10 in winter, UTC+11 in summer. 4h 30m/5h 30m ahead of India.

Finding the Best Meeting Time Between Time Zones

When scheduling meetings across time zones, the goal is to find a window that falls within working hours (roughly 8 AM–6 PM) in all locations simultaneously. Here are the practical overlap windows for common India-based international meetings:

  • India + UAE: Nearly full workday overlap. 9 AM–6 PM IST = 7:30 AM–4:30 PM GST. Excellent overlap.
  • India + UK (BST, summer): 1:30 PM–6 PM IST = 9 AM–1:30 PM BST. Morning UK / afternoon India.
  • India + UK (GMT, winter): 2:30 PM–6 PM IST = 9 AM–11:30 AM GMT. Narrower window.
  • India + New York (EDT, summer): 6:30–9 PM IST = 9 AM–11:30 AM EDT. Evening India / morning NY.
  • India + Singapore: Nearly full overlap. 9 AM–6 PM IST = 11:30 AM–8:30 PM SGT. Most of workday.
  • India + Tokyo: 9 AM–2 PM IST = 12:30 PM–5:30 PM JST. Mid-afternoon Japan / morning India.
