Settings guide
Finding working-hour overlap between teams:
Add all time zones your team operates in. The 24-hour strip color-codes hours: green for standard working hours (9am–5pm), yellow for early/late acceptable hours, red for outside working hours. Drag to find a green block that spans all zones simultaneously.
DST awareness: DST status is shown for each zone on the selected date. If you are scheduling a recurring meeting, check that the overlap is preserved after the next DST transition in any of the zones — transitions in different countries happen on different dates.
UTC as a reference: When communicating times across teams, using UTC eliminates ambiguity. UTC has no DST transitions. "15:00 UTC" is unambiguous; "3pm EST" requires knowing whether EST or EDT is currently in effect.
Half-hour and 45-minute offsets: India Standard Time (IST) is UTC+5:30. Nepal Time is UTC+5:45. Australia's Lord Howe Island is UTC+10:30 in winter and UTC+11 in summer. These zones are less commonly known but significant for teams working with colleagues in those regions.
Format comparison
vs Google search ("time in Tokyo"): Google's time display for a specific city is fast and accurate for the current moment. A dedicated converter is better when you need to convert a specific non-current time, see the overlap between multiple zones on a timeline, or check what a UTC timestamp is in several cities simultaneously.
vs world clock apps: World clock apps show the current time in multiple cities simultaneously. A converter lets you input an arbitrary time and convert it, rather than showing only the current moment. Both are useful for different scenarios.
How it works
Select your time zones
Add the source time zone and one or more target zones. Type a city name or country to search.
Enter or drag a time
Type a specific time, or drag the 24-hour strip to see how times shift across zones as the hour changes.
Read the converted times
All zones show the equivalent local time, UTC offset, DST status, and whether the time falls on the same or adjacent calendar day.
About this format
Converting a time between time zones is simple arithmetic — until DST, half-hour offsets, and 45-minute anomalies enter the picture. A time zone converter does the arithmetic correctly for any date, accounting for Daylight Saving Time transitions and the full range of UTC offsets including the non-standard ones (India at UTC+5:30, Nepal at UTC+5:45, Newfoundland at UTC−3:30).
The most common use is scheduling. You are arranging a call with someone in a different time zone and need to know what your 3pm is in their time zone. Or you receive an email with a meeting time in UTC and need to convert it to your local time. Or you are booking a flight that departs at 23:55 and arrives at 01:30 the next day across a time zone boundary.
This converter shows both the direct time conversion and the relative day — so you can see that "10am Tuesday in New York" is "11pm Tuesday in Tokyo" (same calendar day in this case), or that a Monday morning standup in London corresponds to Sunday evening in Los Angeles.
The scrubbable 24-hour strip is the fastest way to find overlap between teams: drag through the hours and see which times fall within working hours (9am–5pm) for all zones simultaneously.
