Unix timestamps are how computers store time, and they are completely unreadable to humans. EpochConverter translates between the two instantly, in either direction.
A Unix timestamp counts seconds since 1 January 1970 UTC. It is compact, unambiguous across timezones and therefore everywhere in logs, databases and APIs — and completely opaque when you are trying to work out when something happened.
This converter handles both directions. Paste a timestamp to get a human date, or enter a date to get its timestamp. It is careful about the seconds versus milliseconds distinction, which is the single most common source of confusion: JavaScript's Date.now() returns milliseconds while most Unix tooling uses seconds, and mixing them produces dates in 1970 or the year 50000.
A live current-timestamp display is shown on the page, which is handy when you need "now" in epoch form.

Check before you rely on it: free quotas, file limits and pricing change frequently. Confirm current terms on the official site before depending on it for regular work.
Developers reading logs and API responses, database administrators, and anyone debugging why a timestamp looks wrong. If you have ever seen 1700000000 and wondered what date that was, this is the tool.
Yes, both conversion directions are free with no registration.
The number of seconds elapsed since 1 January 1970 UTC. It is the standard way computers represent a point in time.
A 10-digit value is usually seconds; 13 digits usually means milliseconds. Getting this wrong produces dates in 1970 or far in the future.
Yes, enter a date and time and the tool returns the corresponding timestamp.
Yes, you can view conversions in UTC or your local timezone.
Almost always because a milliseconds value was interpreted as seconds, or the value is zero or negative.
