Timezone Converter
Convert a date and time between PST, CST, EST, UTC and other timezones.
Pick a date and time in one timezone and see it converted to any other - PST, CST, EST, UTC, or any IANA timezone - with daylight saving time handled automatically. Useful for scheduling a meeting across offices, checking when a webinar starts in your local time, or converting a server log timestamp to your timezone. Conversion runs locally using your browser's built-in timezone database.
Runs on your device. This tool processes your file inside this browser tab. Nothing is uploaded, so it also works offline once the page has loaded, and closing the tab discards the file from memory.

Common questions
Does this account for daylight saving time?
Yes - conversions use your browser's IANA timezone database, which handles DST transitions automatically.
Can I convert to multiple timezones at once?
Select each target timezone to see the converted time; add as many comparisons as you need.
Is my input sent anywhere?
No - all timezone math runs locally in your browser.
Can I use abbreviations like EST or full IANA names?
Both are supported - common abbreviations and full IANA timezone identifiers like America/New_York.
