What each Time Zone input means

Time in the first zone
The clock time in the first zone. The time box follows your device's 12- or 24-hour format.
From UTC offset
The first zone's UTC offset on the day in question, with example places. In summer, pick the daylight-saving offset — US Eastern is UTC−4, not −5.
To UTC offset
The zone to convert to, chosen the same way.

Time Zone conversion formula

target time = source time − source UTC offset + target UTC offset (± 24 hours across midnight)

Every time zone is an offset from Coordinated Universal Time. To move a time between zones, take away the source offset to get UTC, then add the target offset; if the answer passes midnight, the date changes too, and the page says whether it lands on the previous, the same or the next day. Offsets are not always whole hours — India is UTC+5:30, Nepal UTC+5:45 and Newfoundland UTC−3:30 — and every offset in use is in the lists, from UTC−12 to UTC+14. Daylight saving is the catch: the US Eastern zone is UTC−5 in winter but UTC−4 from the second Sunday in March to the first Sunday in November, so choose the offset in force on the day you mean.

Time Zone conversion worked example

9:00 am in India (UTC+5:30) is 03:30 UTC, and 03:30 − 5 hours is 22:30 the previous evening in New York in winter (UTC−5). In summer, when New York is UTC−4, it is 23:30.

More Time Zone examples

A 14:00 UTC call in India: 5 hours 30 minutes ahead, so 19:30 the same day.

10 pm in New York in summer (UTC−4) is 02:00 UTC, which is 11:00 the next day in Tokyo (UTC+9), 13 hours ahead.

Noon UTC in Kathmandu, UTC+5:45: 17:45 the same day.

Where the Time Zone converter can give the wrong answer

  • Daylight saving is not applied automatically; pick the offset for the date. The US, UK and EU change clocks on different weekends.
  • Offsets east of UTC are positive, west negative. A meeting at 15:00 UTC is 11:00 in New York in summer.
  • Countries occasionally change their offsets; for a city on a future date, check its current rules.
