About the Time Converter
Our free online time converter combines two everyday tools in one place. The Time Units tab converts intervals between seconds, minutes, hours, days, weeks, months, and years — handy for scheduling, project estimates, or just settling a quick debate. The Timezones tab converts any date and time from one timezone into a full set of major world timezones at once, so you can plan meetings and calls across the globe without doing the math yourself.
Everything runs entirely inside your browser using standard JavaScript date APIs — no data is ever uploaded to a server, and Daylight Saving Time is handled automatically for the date you choose.

Frequently Asked Questions
Does it support Daylight Saving Time (DST)?
Yes. The timezone converter uses the browser's standard Date and Intl APIs, which automatically apply the correct Daylight Saving Time adjustment based on the date you select — no manual offset math required.
Are calculations done on a server?
No. All date, time, and unit calculations run entirely inside your browser using standard JavaScript APIs — nothing is uploaded or sent to a server.
Which time units are supported?
Seconds, minutes, hours, days, weeks, months, and years. Months and years use standard average calendar lengths, so 12 months always equals exactly 1 year.
Which timezones are supported?
UTC/GMT, US Eastern (New York), US Pacific (Los Angeles), Israel Standard Time (Jerusalem), Central European Time (Paris/Berlin), Australian Eastern Time (Sydney), and Japan Standard Time (Tokyo).
Does it cost money?
No. The time converter is 100% free to use, with no registration or account required.
