Unix Timestamp Converter
Examples
What you get
Always UTC, never a guess
A Unix timestamp carries no timezone — it is a count of seconds, nothing more. The page shows the date and time in UTC and says so plainly, instead of guessing your own zone.
Both directions
Start from a timestamp and get the date, or start from a date and get the matching timestamp.
Weekday and distance from today
Every result also shows which day of the week it falls on and how many days away it is from today, both worked out from the number itself.
Nothing is stored
The timestamp or date you enter stays on your page. We do not store it or send it anywhere.
How it works
- Enter a Unix timestamp, or choose a date and time.
- Press the matching convert button.
- Get the result in UTC, along with the weekday and how far it is from today.
Worth knowing
What a Unix timestamp is
A Unix timestamp is the number of seconds elapsed since 1 January 1970, 00:00:00 UTC. It carries no timezone of its own — a zone only enters the picture once someone turns it into a date they read, not in the number itself.
Why the page does not show your local time
The site has no way to learn your timezone from the address you requested, so it cannot guess it correctly — a wrong guess would show a confidently precise but false hour. UTC is the one time this page can actually show.
Frequently asked questions
Why doesn't it show my local time?
Because the site does not know your timezone, and a wrong guess would be worse than plainly showing UTC. You add or subtract the offset yourself, once you know it.
What is timestamp 2147483647?
It is the moment a signed 32-bit counter runs out of room — the Year 2038 problem, the timestamp equivalent of the Year 2000 problem.
Can a timestamp be negative?
Yes, for dates before 1 January 1970 — but the pages enumerated here start at 0, that exact moment.
Why do some timestamps have a time other than midnight?
Because they are round or often-searched values, not necessarily the start of a year — 1234567890, for example, falls at 23:31:30 UTC, not midnight.
