⏱️ Understanding Time Zone Offsets
All time zones are expressed as offsets from UTC (Coordinated Universal Time). A "UTC+5:30" offset means that location is 5 hours and 30 minutes ahead of UTC — this is India's IST.
- UTC+14 (Line Islands) is the world's easternmost time zone
- UTC-12 (Baker Island) is the world's westernmost time zone
- India, Iran, Nepal and Myanmar use half-hour or quarter-hour offsets
- During DST, most countries shift their offset by +1 hour

Frequently Asked Questions
New York (EST) is 5 hours behind London (GMT) in winter. The ideal meeting window is 9 AM–12 PM New York time (2–5 PM London). During summer, the gap narrows to 4 hours when the US observes EDT. Use the Meeting Planner tab for a visual overlap grid.
Search and add both cities on the Converter page. Each row shows the local time for that city, updated live. Click any hour tile to compare that exact hour across all your zones. For a specific conversion (e.g. "9 AM Tuesday in Tokyo = what time in Berlin?"), use the Time Difference Calculator page.
Yes. All conversions use your browser's built-in IANA time zone database, which contains DST rules for every country. UTC offsets update automatically when DST transitions occur, so you'll always see the correct, current local time. Check the DST Tracker page for upcoming clock changes in specific countries.
UTC (Coordinated Universal Time) is the modern successor to GMT (Greenwich Mean Time). For practical purposes they're identical — both represent the 0-hour baseline. The key difference: GMT is a time zone observed by countries like the UK in winter, while UTC is a universal standard that never observes Daylight Saving Time. In programming and aviation, UTC is always preferred.
Most countries near the equator skip DST entirely, including China (UTC+8 year-round), India (UTC+5:30), Japan (UTC+9), most of Africa, the Middle East, and Southeast Asia. In the Americas, Arizona (US) and most of South America stay on standard time, and Russia abolished DST in 2014. Visit the DST Tracker page for a full, current list.
There are roughly 38 distinct time zone offsets in use globally, though the standard theory divides the Earth into 24 zones based on 15° longitude increments. Several countries use non-standard half-hour offsets (India UTC+5:30, Iran UTC+3:30) or quarter-hour offsets (Nepal UTC+5:45, Chatham Islands UTC+12:45).

🌐 The Complete Guide to Working Across Time Zones
Why Time Zones Matter for Remote Teams
As remote work goes global, time zone awareness has become a critical workplace skill. Scheduling errors across time zones can cause missed meetings, delayed deliverables, and strained relationships. A 9 AM meeting in New York is a 3 AM alarm in Seoul — understanding these overlaps is essential for sustainable async and sync collaboration.
The best global teams follow a "follow the sun" model: work handoffs rotate across continents so someone is always working. For synchronous meetings, finding a "golden hour" within working hours for all participants is the goal.
Best Practices for Cross-Timezone Collaboration
- Always share meeting times in UTC or include multiple time zones in invites
- Set your calendar to show a secondary time zone for your most frequent collaborator
- Rotate meeting times to share the inconvenience of early/late hours fairly
- Record meetings for teammates in incompatible time zones
- Prefer async-first communication: docs, comments, and recorded videos over live calls
- Use the Meeting Planner page to find the optimal overlap window
