Unix Time Stamp Converter

Convert Unix Timestamps

I would like to introduce you to my free & online Unix timestamp converter.

It's an online time converter for epoch Unix timestamp format. I was missing some features like simple timestamp modifications or calculating the time difference in other converters so I did my own.

What is epoch time?

The Unix epoch (or Unix time or POSIX time or Unix timestamp) is the number of seconds that have elapsed since January 1, 1970 (midnight UTC/GMT), not counting leap seconds (in ISO 8601: 1970-01-01T00:00:00Z).

Literally speaking the epoch is Unix time 0 (midnight 1/1/1970), but "epoch" is often used as a synonym for Unix time.

Some systems store epoch dates as a signed 32-bit integer, which might cause problems on January 19, 2038 when it turns again to 0 (known as the Year 2038 problem or Y2038).

Convert epoch to local date & time

You can enter the epoch timestamp and it will convert it to several human-readable time formats.

Alt Text

Easily modify the timestamp

Adjust provided epoch timestamp by adding years, days or hours.

Alt Text

Calculate time difference

Calculate the difference between two epoch timestamps and display it in numerical and human-readable formats.

    Image description

    Was working on a project that needed to deal with Unix timestamps and stumbled upon this site (unixtime.cn). Usually I hate most timestamp converters because they're cluttered with ads or have terrible UX, but this one is surprisingly clean and straightforward.

    What I like about it:

    • Super minimal interface, no ads or bloat
    • Handles both timestamp → date and date → timestamp conversions
    • Works with seconds, milliseconds, microseconds and nanoseconds
    • Shows multiple time formats (ISO 8601, RFC, etc)
    • Has keyboard shortcuts for quick conversions
    • Dark mode support

    Just thought I'd share in case anyone else deals with timestamps regularly. Beats having to remember the conversion formulas or dealing with those sketchy converter sites.

    Edit: Thanks for the awards! Glad others found this useful too. And no, I'm not affiliated with the site - just a dev who appreciates well-designed tools.

    Unlike other Unix timestamp converters, This one converts and shows in detail
