The Problem with Time Zones
Here's a scenario you've probably lived through: you're trying to figure out what time it is for your colleague in Singapore. You know you're in New York, and you're pretty sure Singapore is "somewhere around 12 hours ahead," but is it 12 or 13? And wait, did they just switch to Daylight Saving Time? Does Singapore even do DST?
The mental gymnastics of timezone conversion is surprisingly error-prone. It's not that the math is hard—it's that there are too many edge cases. DST transitions happen on different dates in different countries. Some places are offset by 30 or 45 minutes instead of whole hours. And when you're tired or rushing, mistakes happen.
This converter does one thing well: it shows you the actual current time in multiple places simultaneously. No calculations needed. What you see is what time it actually is right now.
What Makes This Different
Compare Multiple Cities
Most converters only handle two timezones at once. Ours shows up to 4 cities side-by-side, which is actually useful when you have teammates scattered across the globe.
Always Current
Times update every minute. You don't need to refresh the page or wonder if the displayed time is stale. What you see is what time it is.
DST Handled Automatically
We use the IANA timezone database, the same authoritative source your computer uses. DST transitions, half-hour offsets, all the weird edge cases—handled.
90+ Cities
We cover major business hubs on every continent. From San Francisco to Sydney, Mumbai to Munich. If it's a city where business happens, we probably have it.
How to Use This Tool
The converter above shows New York, London, and Tokyo by default—three cities that cover the major business timezones. But you can customize it:
- Add a city: Click the dashed "Add City" card and search for any city. Start typing and it'll show matches.
- Remove a city: Hit the X in the top-right corner of any city card.
- Check the status: Each card is color-coded. Green means it's working hours there (9am-6pm), amber means early morning or evening, red means it's the middle of the night.
If you need to plan a specific meeting time rather than just check current times, the full meeting planner lets you pick a date and time and see how it translates across all your cities.
Tips for Working Across Time Zones
Learn Your Key Offsets
You don't need to memorize every timezone, just the ones you deal with regularly. London to New York is usually 5 hours. Tokyo to London is usually 9 hours. Once you know your key offsets, quick mental checks become easier.
Watch for DST Transitions
The US, Europe, and Australia all change clocks on different dates. For about 3-4 weeks in spring and fall, your usual offsets will be off by an hour. Mark DST dates in your calendar to avoid confusion.
Use UTC for Async Communication
When posting deadlines or schedules to a distributed team, consider including UTC time. It's the one timezone that never changes (no DST) and everyone can convert from it without confusion.
Frequently Asked Questions
Does the time zone converter handle Daylight Saving Time?
Yes. We use IANA timezone database (the same one your operating system uses) which automatically handles DST transitions. When you check a time in March or November, you'll see the correct offset even during DST changeover periods.
How many cities can I compare at once?
You can compare up to 4 cities in the quick converter on this page, or up to 8 cities in the full meeting planner. This covers most team configurations without cluttering your screen.
Can I convert times for a future date?
The quick converter shows current time. For future date conversions with DST awareness, use the full meeting planner where you can pick any date and the tool will calculate the correct time difference for that specific day.
Why do some cities show different offsets at different times of year?
Many countries observe Daylight Saving Time, shifting clocks forward in spring and back in fall. Not all countries do this, and those that do don't always change on the same dates. Our converter accounts for all of this automatically.
What timezone format do you use?
We use IANA timezone names (like "America/New_York" or "Europe/London") rather than abbreviations like EST or GMT. This eliminates ambiguity and ensures accurate conversions across DST boundaries.
