Unix Timestamp Converter: Dates and Times in Seconds
9 min read
A Unix timestamp is the number of seconds since January 1, 1970 00:00:00 UTC. Logs, APIs, and databases often store dates this way. A Unix timestamp converter turns a timestamp into a readable date and time, or a date into a timestamp, so you can debug and integrate easily.
Why timestamps?
- Simple: One number instead of timezone and format rules.
- Sortable: Comparing numbers is easy; no date parsing needed.
- Universal: Same moment in time everywhere (UTC-based).
Seconds vs milliseconds
- Seconds: Classic Unix timestamp (10 digits for recent dates). Used in many systems and APIs.
- Milliseconds: JavaScript and some APIs use milliseconds (13 digits). Check your context before converting.
Our Unix Timestamp Converter supports seconds. Enter a timestamp to see the date, or pick a date to get the timestamp. You can also get the current time. All conversion is in your browser.
