How to use the time zone converter
Enter the date and time in the first zone, choose the zone you are converting from and the zone you are converting to, and read the result — with the weekday and a “next day” or “previous day” note where it applies. Tap “Use current time” to start from right now. The world-clock row shows the same instant in four major cities.
Daylight saving, handled for you
Time-zone offsets are not fixed — many regions move their clocks forward in spring and back in autumn, on different dates. This converter reads the offset for the exact date you enter, so a summer conversion and a winter one between the same two cities can correctly differ by an hour. You never have to remember who is on daylight saving.
Frequently asked questions
Automatically. It uses your browser's built-in time-zone database, which knows when each region starts and ends daylight saving, so the conversion is correct for the exact date you choose — not just a fixed offset.
Because the world spans more than 24 hours of offset. Convert an evening in New York to Tokyo and it is the next morning there; the converter labels the result ‘next day’ or ‘previous day’ so you are never caught out.
UTC (Coordinated Universal Time) is the global reference time that every time zone is measured against. It does not change for daylight saving, which makes it handy for scheduling across countries.
Yes. Enter the meeting time in your own zone, pick the other person's zone, and you will see their local time instantly — and the world-clock row shows several other cities at a glance.
