What is a Time Zone Converter?
A time zone converter helps you figure out what time it is (or will be) in different parts of the world. It's essential for scheduling international meetings, coordinating with remote teams, or planning calls with friends and family abroad.
The world has over 24 time zones (it's complicated—some are 30 or 45 minutes offset). This tool shows you how times align across multiple zones at once, so you can find times that work for everyone.
Meeting Scheduling
Find times that work for teams across multiple time zones
All Major Zones
Covers cities and zones worldwide including DST
24-Hour Visual Grid
See a full day's hours aligned across zones
Business Hours Overlap
Instantly see which hours are reasonable in all locations
Common time zone challenges this solves:
- Remote work — Coordinating with colleagues in SF, London, and Singapore
- International calls — Finding a reasonable time to call family abroad
- Live events — Converting event times for webinars, sports, streams
- Travel planning — Understanding arrival times after long-haul flights
- Stock markets — Knowing when NYSE, LSE, or Asian markets open
UTC Offsets and DST Dates for Popular Cities
Every zone in the grid is stored as an offset from UTC. The tricky part is that many places switch offset twice a year for daylight saving. The table below lists the standard (winter) offset, the summer offset, and the exact switch dates so you can tell which one is active on the day you care about.
| City | Standard | DST | DST period |
|---|---|---|---|
| Los Angeles / SF | UTC-8 | UTC-7 | 2nd Sun Mar - 1st Sun Nov |
| New York | UTC-5 | UTC-4 | 2nd Sun Mar - 1st Sun Nov |
| London | UTC+0 | UTC+1 | Last Sun Mar - Last Sun Oct |
| Berlin / Paris | UTC+1 | UTC+2 | Last Sun Mar - Last Sun Oct |
| Dubai | UTC+4 | none | No DST |
| Bangalore / Mumbai | UTC+5:30 | none | No DST |
| Singapore | UTC+8 | none | No DST |
| Beijing / Shanghai | UTC+8 | none | No DST |
| Tokyo | UTC+9 | none | No DST |
| Sydney | UTC+10 | UTC+11 | 1st Sun Oct - 1st Sun Apr |
Worked example: a 3-way standup across three continents
Say your team sits in San Francisco (UTC-8 in winter), Berlin (UTC+1), and Bangalore (UTC+5:30). Berlin runs 9 hours ahead of San Francisco, so 8:00 AM in SF is 5:00 PM in Berlin. Bangalore is 13.5 hours ahead, so the same moment is 9:30 PM there. That single 8 AM slot lands at end-of-day for Berlin and bedtime for Bangalore.
Slide the window earlier and it gets worse for Bangalore; slide it later and Berlin is offline. The least painful overlap is roughly 7 to 9 AM San Francisco time, which is 4 to 6 PM in Berlin (still inside the workday) and 8:30 to 10:30 PM in Bangalore (late, but awake). With a 13.5 hour spread there is no window that is comfortable for all three, so someone always compromises.
Conversions people search for most
- EST to IST — add 10:30 in winter, or 9:30 while New York is on EDT. 9:00 AM in New York is 7:30 PM in Bangalore.
- PST to GMT — add 8 hours. 10:00 AM in San Francisco is 6:00 PM in London.
- EST to CET — add 6 hours. 8:00 AM in New York is 2:00 PM in Berlin.
- GMT to AEST — add 10 hours. 9:00 AM in London is 7:00 PM in Sydney.
Daylight saving gotchas
The US and EU do not switch on the same weekend. US clocks spring forward on the second Sunday of March, but the EU waits until the last Sunday. For those two or three weeks, New York has already moved to EDT (UTC-4) while London is still on GMT, so the gap is 4 hours instead of the usual 5. The reverse happens in autumn, when Europe falls back a week before the US does. The Southern Hemisphere flips the whole calendar: Sydney observes DST from October to April, so it is on summer time exactly when the north is on winter time.
