How it works
- 01
Choose two places
Search by country or city. TimeGap starts from your own time zone when your browser reports it.
- 02
Read the difference
Both local times, both dates, both UTC offsets, and whether the other place is already on a different day.
- 03
Check a specific hour
Enter a time to see exactly what it becomes on the other side, then copy the result or the link.

Meeting Time Finder
Comparing two clocks answers what time is it there. Scheduling across three or four cities is a different problem: you need the hours when everybody is actually at their desk. The Meeting Time Finder takes up to five cities and your working hours, then shows the overlap.
Open the Meeting Time FinderWhy time differences are not fixed
A time difference is the gap between two UTC offsets at a given moment, and both offsets can move. Roughly a third of the world changes clocks twice a year, on different dates and in opposite directions depending on the hemisphere. Between March and April, and again between September and November, pairs of countries drift by an hour for a few weeks before settling.
That is why a memorised number eventually goes wrong. Santiago and Madrid are 6 hours apart during the southern winter and 4 hours apart during the southern summer, with two short stretches of 5 hours in between. New York and London are usually 5 hours apart, but for two weeks each March the gap is 4.
TimeGap reads the current rules for each zone rather than storing a fixed number, so the answer reflects the date you are asking about — including the weeks when the usual answer is wrong.
Frequently asked questions
How do I find the time difference between two countries?
Pick the place you are in and the place you want to compare. TimeGap shows both local times, both UTC offsets and the exact difference in hours and minutes. You can also enter a specific time to see what it corresponds to in the other place.
Does TimeGap handle daylight saving time?
Yes. Every calculation uses IANA time zone data through your browser, so summer time is applied automatically for the date being compared. This matters because the difference between two places can change several times a year — Chile and Spain, for example, are 6 hours apart in August but only 4 hours apart in January.
Why does a country sometimes have more than one time zone?
Large countries such as the United States, Brazil, Mexico, Canada, Australia and Russia span several zones. On country pages TimeGap uses the most widely used zone and says so explicitly, so you can switch to a specific city when precision matters.
Is TimeGap free and does it need an account?
TimeGap is free and needs no account. The calculator runs entirely in your browser, and no location permission is requested — your time zone is read from your device settings only if you let the browser report it.
What is a UTC offset?
UTC is the global reference time. An offset such as UTC-4 means the local clock is 4 hours behind that reference. The difference between two places is simply the difference between their two offsets at that moment.
How do I pick a good time for an international meeting?
Use the Meeting Time Finder. Add up to five cities, set your working hours, and it highlights the periods when everyone is available. If no window exists, it shows the closest workable options.
How many time zones does the US have?
Six primary time zones — Eastern, Central, Mountain, Pacific, Alaska and Hawaii — plus Arizona, which keeps Mountain Standard Time year-round instead of switching to daylight saving with the rest of the Mountain zone. See the US time zones page for current times, UTC offsets and every zone-to-zone comparison.
When does daylight saving time end this year?
Most of the US changes its clocks on the second Sunday of March and the first Sunday of November. The daylight saving time page shows the exact upcoming date, computed live, plus which states and territories skip it entirely.
