Time Zone Converter
Convert time between different time zones worldwide.
📖 Understanding Time Zones
Time zones are regions of the Earth that have the same standard time. They are roughly based on longitude, with each zone typically differing by one hour from adjacent zones.
Key Time Zones
- UTC - Coordinated Universal Time (the reference)
- EST/EDT - Eastern Time (UTC-5/UTC-4)
- PST/PDT - Pacific Time (UTC-8/UTC-7)
- GMT/BST - Greenwich/British Time (UTC+0/UTC+1)
- CET/CEST - Central European Time (UTC+1/UTC+2)
- JST - Japan Standard Time (UTC+9)
💡 Tip: Many regions observe Daylight Saving Time (DST), which shifts the clock forward by one hour during summer months. This converter automatically accounts for DST.

Yes! The converter uses your browser's built-in timezone data, which includes DST transitions. It will automatically adjust for DST based on the selected date.
UTC (Coordinated Universal Time) is the primary time standard by which the world regulates clocks. It's essentially the same as GMT but is the official scientific reference. All time zones are expressed as offsets from UTC.
Some countries chose non-standard offsets to better align with their geographical position or for political reasons. Examples include India (UTC+5:30), Nepal (UTC+5:45), and parts of Australia (UTC+9:30).
