Frequently Asked Questions
What is a Unix timestamp?
A Unix timestamp (also known as Epoch time or POSIX time) is the number of seconds that have elapsed since January 1, 1970 00:00:00 UTC, not counting leap seconds. It is widely used in computing to represent a specific point in time as a single number.
How to convert a Unix timestamp to a human-readable date?
Enter the Unix timestamp in the input field above and the tool will instantly convert it to a human-readable date. It supports both seconds (10 digits) and milliseconds (13 digits) formats, and shows results in multiple formats including ISO 8601 and locale-specific strings.
What is the difference between seconds and milliseconds timestamps?
A seconds timestamp is a 10-digit number representing seconds since Unix epoch (e.g. 1700000000). A milliseconds timestamp is a 13-digit number representing milliseconds since Unix epoch (e.g. 1700000000000). JavaScript's Date.now() returns milliseconds, while many server-side languages use seconds.
What is epoch time?
Epoch time refers to the Unix epoch, which is January 1, 1970 00:00:00 UTC. The Unix timestamp counts the number of seconds since this epoch. The term "epoch" simply means the starting point from which time is measured in this system.
How do time zones affect timestamp conversion?
Unix timestamps are always in UTC and are timezone-independent. However, when converting a timestamp to a human-readable date, the result depends on the selected timezone. The same timestamp will show different local times in different timezones. Use the timezone dropdown above to see the date in your preferred timezone.
