Time Zone Converter is a free tool that shows what time it is, or will be, in cities around the world. Pick a date and time, and see it in every city you’ve added, with the correct daylight saving rules for that date. A meeting planner shows everyone’s working hours side by side, so you can find a time that suits all of them.
How to convert a time between time zones
- Your own time zone is filled in, with the current date and time. Change the Date and Time if you’re planning ahead.
- Add cities: type a city, a country or an abbreviation such as IST, PST or CET, and choose from the list.
- Read the time in each city. A “+1 day” note means it’s already tomorrow there.
- To enter the time in another city instead, click Make main next to it.
Finding a meeting time
Tick Show meeting planner to see the day hour by hour in every city. Green hours are normal working hours (9:00–17:00), amber hours are early morning or evening, and grey hours are night. Look for a column that is green, or at least amber, for everyone, and click it to use that time.
Daylight saving, explained
Many countries move their clocks forward an hour in spring and back in autumn, but not all on the same day. The US changes on the second Sunday of March and the first Sunday of November, while the UK and EU change on the last Sundays of March and October. For a few weeks each year, New York and London are 4 hours apart instead of 5. The southern hemisphere does the opposite: Sydney is on summer time from October to April. Countries such as India, Japan and China don’t change their clocks at all. The converter follows all these rules automatically, and tells you when each city’s clocks next change.
Common conversions
- New York and India: India is 9 h 30 min ahead of New York in winter and 10 h 30 min in summer, so 9:00 in New York is 19:30 or 18:30 in India.
- London and Los Angeles: 8 hours apart for most of the year.
- Sydney and London: between 9 and 11 hours apart, depending on the time of year.
Working with computer timestamps instead? Use the Unix Timestamp Converter, or the ISO 8601 Converter for dates with time zone offsets.
Frequently asked questions
Does it handle daylight saving time?
Yes. It uses the official time zone database built into your browser, so every conversion uses the clock rules in force on that exact date. Each zone also shows whether it’s on summer time and when its clocks next change.
What happens at 2:30 am on the night the clocks change?
When clocks spring forward, some local times never happen; the converter tells you and shows the time the clocks actually displayed. When they fall back, an hour happens twice; it tells you that too and shows the first one.
What’s the difference between EST and EDT, or GMT and BST?
EST and GMT are the winter (standard) times; EDT and BST are the summer (daylight) times, one hour ahead. Rather than guessing which applies, pick the city and the converter uses the right one for your date.
Why do some places have half-hour offsets?
A few countries set their clocks to a half or quarter hour: India is UTC+5:30, Nepal UTC+5:45, and parts of Australia UTC+9:30. The converter handles these like any other zone.
Are my cities saved?
The list of cities you add is remembered in this browser only, so it’s there next time. It’s never sent anywhere.
