FAQ
How does this handle daylight saving time?
This tool uses your browser's built-in time zone database, which automatically accounts for daylight saving rules currently in effect for each region, so conversions reflect the correct offset for today's date.
Why do some time zones have unusual offsets?
Some regions use half-hour or 45-minute offsets rather than full hours (for example, India and parts of Australia), which is a real feature of how time zones are defined, not an error.
Can I convert times across dates, like late at night?
This tool shows the equivalent time in the target zone; if the conversion crosses midnight, the resulting time reflects the correct hour but keep in mind it may fall on the next or previous calendar day depending on the direction of the conversion.
What is this useful for?
Common uses include scheduling calls or meetings with people in other countries, planning travel, or figuring out what time a live event airs in your local time zone.
What are the standard UTC offsets for major time zones?
UTC offsets range from about UTC−8 on the U.S. West Coast to UTC+9 or higher in parts of Asia and Australia. See the reference table above for common zones — remember that many of them shift by an hour during daylight saving time.
Why does India use a 30-minute offset (UTC+5:30) instead of a whole hour?
India Standard Time was set at UTC+5:30 so that a single time zone could split the difference across the country's wide east-west span, centered on a reference longitude roughly through the middle of the country, rather than rounding to a whole-hour zone.
Which countries or regions don't observe Daylight Saving Time?
Most of Asia, Africa, and countries near the equator skip daylight saving time, since their day length barely changes across the year. Notable examples include Japan, China, and India, along with most of Arizona in the United States.
What time is it in London when it is 9 AM in New York?
Usually 2:00 PM, since London is 5 hours ahead. For roughly three weeks in March, and a week in late October, the gap is 4 hours, so it is 1:00 PM.
Why does the time difference between two cities change during the year?
Countries change their clocks on different dates, or not at all. When one place has moved to summer time and the other has not, the gap changes by an hour until both have changed.
Which countries do not use daylight saving time?
Many do not, including India, Japan, China and most of Africa and Asia. Their offsets stay the same all year, so the gap to places that do change moves by an hour.
About this tool
This tool converts a time from one time zone to another, using your browser's time zone data so daylight saving rules are handled automatically. Useful for scheduling across regions, planning travel, or checking event times in your local zone.
Worked examples
A 9:00 AM meeting in New York converts to different times around the world, and the answer depends on the date because of daylight saving.
| Los Angeles | New York | London | Paris | Kolkata | Tokyo | Sydney |
|---|---|---|---|---|---|---|
| 6:00 AM | 9:00 AM | 2:00 PM | 3:00 PM | 7:30 PM | 11:00 PM | 1:00 AM (+1 day) |
| Los Angeles | New York | London | Paris | Kolkata | Tokyo | Sydney |
|---|---|---|---|---|---|---|
| 6:00 AM | 9:00 AM | 1:00 PM | 2:00 PM | 6:30 PM | 10:00 PM | 12:00 AM (+1 day) |
In March the US changes its clocks before Europe does, so for about three weeks the gap between New York and London is 4 hours and not the usual 5. The same thing happens for about a week in late October. The converter uses the date of today, so check the date of your meeting if it falls near a clock change.
| Los Angeles | New York | London | Paris | Kolkata | Tokyo | Sydney |
|---|---|---|---|---|---|---|
| 1:00 AM | 4:00 AM | 9:00 AM | 10:00 AM | 1:30 PM | 5:00 PM | 6:00 PM |
When clocks change in 2026
| Region | Clocks go forward | Clocks go back |
|---|---|---|
| United States (e.g. New York) | 8 March 2026 | 1 November 2026 |
| UK and Ireland | 29 March 2026 | 25 October 2026 |
| Central Europe (Paris, Berlin) | 29 March 2026 | 25 October 2026 |
| Australia (Sydney) | 4 October 2026 | 5 April 2026 |
| India, Japan, China | No change | No change |
| Period | New York is behind London by |
|---|---|
| 1 January to 7 March 2026 | 5 hours |
| 8 March to 28 March 2026 | 4 hours |
| 29 March to 24 October 2026 | 5 hours |
| 25 October to 31 October 2026 | 4 hours |
| 1 November to 31 December 2026 | 5 hours |
Because regions change on different dates, offsets between them are not constant all year. Southern hemisphere countries such as Australia move their clocks in the opposite direction from the north, since summer is in December.
Scheduling across time zones
- Send the date and the zone. Write "Tuesday 3 November, 14:00 GMT" and not "2 pm my time", so everyone can check it.
- Find the overlap. Working hours of 9 to 5 overlap by about three hours between New York and London, and not at all between New York and Tokyo or Sydney, so one side must work early or late.
- Rotate the inconvenient slot. If a team spans several continents, share the awkward times fairly.
- Allow for the date line. A late-evening meeting in the Americas can be the next day in Asia and Australia, as the "+1 day" entries show.
