How to use the World Time Converter

  2. Choose the zone you want to convert to.
  3. Read the converted time instantly, and use the World Clock to compare several cities at once.

India Time (IST) and UTC

IST (Indian Standard Time) is UTC+5:30 all year — India does not observe daylight saving, so the offset never changes. UTC (Coordinated Universal Time) is the global reference clock other zones are measured from; it also stays fixed year-round. Many countries do shift by an hour for daylight saving, so their gap to IST changes between summer and winter.

Popular time zones vs IST

City / zoneUTC offsetRoughly vs IST
New York (ET)UTC−5 / −4 (DST)IST − 9:30 to 10:30
London (UK)UTC+0 / +1 (DST)IST − 4:30 to 5:30
Dubai (GST)UTC+4IST − 1:30
Singapore (SGT)UTC+8IST + 2:30
Sydney (AET)UTC+10 / +11 (DST)IST + 4:30 to 5:30
Los Angeles (PT)UTC−8 / −7 (DST)IST − 12:30 to 13:30

Offsets that show two values change with daylight saving; the converter above always uses the correct current offset for the date you enter.

Planning a meeting across time zones

Enter the proposed time in your own zone and convert it to each attendee's zone to find a slot that isn't the middle of anyone's night. The World Clock is handy for a quick side-by-side of everyone's current time before you send the invite.
