Timestamp → Date

Seconds and milliseconds are both accepted — the digit count decides, or pick a unit. The timezone explorer below follows whatever you enter here.

Common questions

Are timestamps processed locally?
Yes. Everything is computed in your browser with your own date support — nothing is uploaded.
Does it handle seconds and milliseconds?
Yes. It auto-detects whether a pasted value is in seconds or milliseconds, and converts in both directions with a timezone selector, ISO 8601 and RFC 2822 output.
What else can it show?
The live current Unix time in seconds and milliseconds, one instant compared across timezones, day-of-year and ISO week numbers, and a duration calculator between two times.
