Time Zone Converter
Pick a moment in one zone and read it in another - daylight saving handled for you, plus a five-city comparison.

Same moment around the world
How the conversion works
A time zone converter has one job: take a wall-clock time that means something in one place and tell you what the clock reads in another place at that same instant. The hard part is daylight saving. Because zones spring forward and fall back on different dates, the gap between two cities is not fixed - London is five hours ahead of New York for most of the year, but for a couple of weeks each spring and autumn it is four or six. This tool reads the offset for the exact date you choose from your browser time zone database, so those wrinkles are handled without you thinking about them.
Reading the comparison strip
Under the main result, the same moment is shown in five major hubs - New York, London, Paris, Dubai and Tokyo. It is a quick sanity check when you are scheduling a call: pick a time that is not the middle of the night for anyone, then copy that instant into your calendar invite.
Common offsets to remember
- UTC / GMT - the zero line. London sits here in winter, one hour ahead in summer.
- New York - UTC-5 in winter, UTC-4 in summer (five hours behind London).
- Los Angeles - three hours behind New York, so UTC-8 or UTC-7.
- India - UTC+5:30 all year, one of the half-hour zones, with no daylight saving.
- Tokyo - UTC+9 all year, also with no daylight saving.
- Sydney - UTC+10 or UTC+11, and its summer is the northern hemisphere winter.
Working with dates and durations
If you are counting the days until an event rather than converting a clock, the date calculator works out the gap between two dates. To add or subtract hours and minutes - useful for timesheets that cross a shift boundary - try the time calculator. Developers converting Unix epoch values will want the timestamp converter instead.
