Time Zone Converter — free online tool

Remote teams compare “now” in two IANA zones and shift a meeting time without guessing daylight-saving offsets.

Cross-check anything that affects money or health with a qualified professional or official source.

How to use Time Zone Converter

  1. Pick two IANA time zones on the Time Zone Converter.
  2. Read live clocks for “now” in each zone.
  3. Enter a local date-time in one zone to see the matching instant in the other.
  4. Account for daylight saving—zones update rules independently of this page.

Practical tips

  • Pick IANA zones (e.g. Asia/Karachi) rather than fixed offsets so daylight saving is handled.
  • Schedule recurring calls by a host city, since offsets drift twice a year in many regions.
  • Double-check the date—converting across the dateline can land you on the next day.

Limitations

Time Zone Converter uses simplified formulas. Tax brackets, bank rounding, leap seconds, and regional holidays are not modelled—confirm important totals with an official calculator or advisor.
