Timestamp converter

Paste or type a time and see it in every form. Each row is copyable with Enter.

The launcher showing a Unix timestamp as seconds, milliseconds, ISO 8601, a Tokyo time and a relative time.

What it shows

Unix seconds, Unix milliseconds, ISO 8601 in UTC and in your local zone (with offset), the date in your local zone, the RFC 2822 / HTTP date, and a relative description such as “3 days ago”.

What you can type

now (or ts) for the current time.
A bare number of 9 or more digits, read by length: 10 digits are seconds, 13 are milliseconds, 16 are microseconds, 19 are nanoseconds.
With the ts prefix: any number, decimals, negatives and a unit: ts 1700000000.5, ts 1700000000000 ms.
ISO dates: 2026-11-06T12:00:00Z, 2026-11-06T13:00:00+01:00, 2026-11-06 12:00, 2026-11-06. With no zone it reads your local time and also lists the values as if it were UTC.
Offsets from now: ts +3d, now - 90 minutes, ts +1.5h (units s m h d w).
Other date text with the ts prefix is parsed by the browser: ts Nov 6 2026 12:00 UTC.
Add in <time zone> for an extra row in that zone: 1700000000 in Asia/Tokyo.

Copied conversions are saved in Recent; reopening one re-runs it, so now is the current time again.
