About Time Zone Converter

A time zone converter that converts any time between world time zones. Features major city presets (New York, London, Tokyo, Sydney, Dubai, etc.), shows UTC offsets, displays current local times, and indicates daylight saving time status. Supports both named zones and UTC±offset format. All computation uses the browser's Intl API. Essential for remote teams, international meetings, and travel planning.

Time Zone Converter Features

  • Major city presets
  • UTC offsets
  • Current times
  • DST indicators
  • Bidirectional
With 38 different time zones worldwide (including half-hour and quarter-hour offsets), converting times accurately is surprisingly complex. Daylight saving time further complicates matters, as not all regions observe it and transition dates vary. This converter handles all these edge cases using the browser's built-in Intl API.

How to Use

Convert between time zones:

  • Source zone: Select 'from' city or UTC offset
  • Target zone: Select 'to' city or UTC offset
  • Time: Enter the time to convert

Notable Time Zones

  • UTC: Coordinated Universal Time (GMT)
  • EST/EDT: US Eastern (UTC-5/-4)
  • PST/PDT: US Pacific (UTC-8/-7)
  • IST: India (UTC+5:30)
  • JST: Japan (UTC+9)

Daylight Saving Time

Most of North America and Europe observe DST (spring forward, fall back). Asia, Africa, and most of South America do not. Australia observes it in reverse (October-April).
