Time Zone Converter
The Time Zone Converter converts times between different time zones around the world. It handles all major time zones including UTC, EST, PST, GMT, IST, JST, and more. The converter automatically accounts for daylight saving time (DST) where applicable. This tool is essential for scheduling international meetings, coordinating with remote teams, planning travel, and any scenario involving multiple time zones.
Formula
Time zone conversion: - UTC offset: hours from UTC - DST: +1 hour in summer (where applicable) - Conversion: add/subtract offset difference Common zones: - UTC: +0 - EST (US Eastern): -5 (EST) / -4 (EDT) - PST (US Pacific): -8 (PST) / -7 (PDT) - IST (India): +5:30 - JST (Japan): +9
Example
Convert: 2026-09-09 14:00 EST UTC: 2026-09-09 18:00 PST: 2026-09-09 11:00 GMT: 2026-09-09 18:00 IST: 2026-09-09 23:30 JST: 2026-09-10 03:00
How to Use
- Enter the date and time to convert
- Select the source time zone

- Optionally convert to multiple zones at once
Frequently Asked Questions
What is UTC?
UTC (Coordinated Universal Time) is the primary time standard by which the world regulates clocks. It is similar to GMT (Greenwich Mean Time) but more precise. All time zones are defined as offsets from UTC (e.g., EST is UTC-5).
What is daylight saving time (DST)?
DST is the practice of advancing clocks by one hour during summer months to extend evening daylight. Not all countries observe DST. The converter automatically applies DST when the selected date falls within the DST period for the relevant time zone.
How do I schedule a meeting across time zones?
Enter the meeting time in one time zone, and the converter shows the equivalent time in all other zones. Choose a time that works for all participants. Tools like World Clock and Time Zone Converter help find overlapping working hours.
What is the difference between GMT and UTC?
GMT (Greenwich Mean Time) is based on the Earth's rotation. UTC is based on atomic clocks and is more precise. For practical purposes, GMT and UTC are the same. UTC is the modern standard; GMT is still used informally.
Why does India have a 30-minute offset?
India uses IST (Indian Standard Time) which is UTC+5:30. Some countries use 30-minute or 45-minute offsets instead of full hours. This is due to historical, geographical, or political reasons. The converter handles these fractional offsets correctly.
