The current Unix timestamp right now, free and updating live.
A Unix timestamp counts seconds elapsed since midnight UTC on January 1, 1970 (the "epoch"). It is the standard way computers store a point in time internally, because it is a single number rather than a locale-dependent string, which makes it easy to compare, sort, and store across systems and time zones.
This tool converts a timestamp into a readable date in your local time zone, and does the reverse — pick a date and time, get the corresponding epoch seconds. It also shows the current timestamp, updating live, which is handy when you need a "right now" reference value for testing.
Watch for the seconds-vs-milliseconds mismatch: JavaScript’s Date object works in milliseconds, while Unix timestamps in APIs and databases are usually in seconds — this tool assumes seconds input, matching the common convention.
Seconds — the standard Unix timestamp convention used by most APIs and databases. JavaScript internally uses milliseconds, so this tool multiplies by 1000 before converting.
The output uses your browser’s local time zone. The same timestamp will display differently depending on where you are.
Systems that store timestamps as 32-bit signed integers will overflow on January 19, 2038. This tool uses JavaScript numbers, which do not have that limit.
