Frequently Asked Questions
What is a Unix timestamp?
A Unix timestamp is the number of seconds elapsed since January 1, 1970, at 00:00:00 UTC (the Unix epoch). It's a universal way to represent time in programming, databases, and APIs.
What formats does the date-to-timestamp converter accept?
Accepted formats include YYYY-MM-DD, YYYY-MM-DD HH:MM:SS, YYYY-MM-DD HH:MM, and ISO 8601 with a Z suffix for UTC.
What is the difference between seconds and milliseconds?
Standard Unix timestamps count seconds since epoch. Millisecond timestamps (used in JavaScript's Date.now()) multiply this by 1000. Both values are shown in the result so you can use whichever your system expects.
How do I convert a timestamp to my timezone?
Adjust the UTC offset and the converter shows the date and time for that timezone, alongside the UTC and ISO 8601 values.
Is the Unix Timestamp Converter free?
Yes. It is completely free with no signup, and all conversions run in your browser — nothing is uploaded.
