Frequently Asked Questions
What is a Unix timestamp?
A Unix timestamp is the number of seconds (or milliseconds) elapsed since January 1, 1970 00:00:00 UTC. It's a universal way to represent a point in time that is timezone-independent and widely used in programming, databases, and APIs.
How do I convert a Unix timestamp to a readable date?
Enter the Unix timestamp in the input field and click Convert. The tool displays the equivalent date and time in UTC and your local timezone. Millisecond timestamps (13 digits) are also supported.
What is the maximum Unix timestamp (Year 2038 problem)?
32-bit systems can only store timestamps up to 2,147,483,647 — which corresponds to January 19, 2038. Modern 64-bit systems handle timestamps far beyond this date. Most web applications use 64-bit integers or ISO 8601 strings to avoid this issue.
Can I convert a date and time back to a Unix timestamp?
Yes. Enter a date and time in the human-readable input and click Convert to get the corresponding Unix timestamp in both seconds and milliseconds. Useful for constructing API queries or database filters.
