Free Time Zone Converter
Pick two time zones and a time to see the exact converted time, the date, and the difference between them — with a full 24-hour comparison so you can find a slot that works for everyone.
What is the time zone converter?
A time zone converter is a free tool that shows what a given time in one location is in another. You pick two time zones and a time, and it calculates the exact converted time, the date it falls on and the difference in hours between them. Slashit's converter uses your browser's built-in time-zone engine, so it accounts for daylight saving time automatically and stays accurate all year. It also shows a full 24-hour comparison of both zones side by side, which makes it easy to schedule calls and meetings across cities and countries.
How our free time zone converter works
Pick two time zones
Choose the “from” and “to” zones from the list of major cities and regions, or use the swap button to reverse the direction.
Set the date and time
Enter the source date and time. The converted time, date and daylight-saving abbreviation update instantly.
Compare all 24 hours
Scan the hour-by-hour table to find a slot that lands in working hours for both zones before you schedule.
What can you use the time zone converter for?
Scheduling a call across countries
Comparing several cities at once shows immediately which hour is reasonable for everyone, rather than working out each offset separately.
Planning a remote team's meeting slot
With a team spread across continents, the 24-hour comparison makes the overlap — and who ends up on a late call — obvious.
Working out a webinar or launch time
Announcing a single UTC time confuses attendees. Checking the local time in your main markets helps you pick a slot that actually suits them.
Coordinating with clients abroad
Freelancers billing internationally need to know when a client's working day starts before promising a delivery time.
Sharing the times you found
The shareable card turns a comparison into an image you can drop into a chat or post, instead of retyping the times.
Who uses our free time zone converter?
Remote & distributed teams
Find a meeting time that works across offices and countries without doing the maths in your head.
Freelancers & agencies
Schedule calls with clients in other regions and quote deadlines in their local time with confidence.
Travellers & event planners
Line up flights, calls and live events across zones, and know exactly what time it is back home.
Why use the time zone converter?
Daylight-saving accurate
It uses the real time-zone rules for each region, so conversions stay correct through DST changes.
Full 24-hour view
See both zones hour by hour to spot the overlap where everyone is awake and at their desk.
Instant and free
No sign-up and no waiting — pick your zones and the answer appears immediately.
Tips for getting the best results
Watch for daylight saving
Offsets shift by an hour when clocks change, and countries change on different dates. Always check the actual date you're scheduling for, not today.
Confirm in writing with the city named
“3pm London time” is far less ambiguous than “3pm GMT”, since London is on BST for much of the year.
Aim for the overlap, then rotate
When no time suits everyone, agree a rotation so the same person isn't always taking the 6am call.
Remember the half-hour zones
India, parts of Australia and Newfoundland run on 30- or 45-minute offsets, which is easy to miscalculate by hand.
Frequently asked questions
Does the converter handle daylight saving time?
Yes. It uses your browser's built-in time-zone database, which applies each region's daylight-saving rules automatically, so results stay accurate year-round.
Which time zones are supported?
Major cities and regions across the Americas, Europe, Africa, Asia and Oceania are included, plus UTC. You can swap the two zones with one click.
Is it free to use?
Yes. The time zone converter is completely free, with no sign-up required.
How do I find a good meeting time?
Use the 24-hour comparison table: it lines up every hour in both zones so you can quickly see when working hours overlap.
How do I convert between two time zones?
Choose your reference zone and time, then add the cities you want to compare. Each one shows the matching local time and date side by side, including any day difference.
Does this account for daylight saving time?
Yes. Conversions use your browser's own time zone database, so daylight saving is applied correctly for the date you select.
Why does the date sometimes differ?
Time zones span more than 24 hours in total, so a late evening in one city can already be the next morning elsewhere. The date is shown alongside each time so you don't book the wrong day.
What does GMT+6 mean?
It means that zone is six hours ahead of Greenwich Mean Time. The offset appears next to each city name so you can see at a glance how far apart two places are.
Can I share the converted times?
Yes. You can export the comparison as an image card, which is easier to paste into a chat or social post than retyping every time zone.
