Date guide
What is a UNIX timestamp?
A UNIX timestamp represents the seconds elapsed since January 1, 1970 at 00:00:00 UTC. It is a compact way to represent a specific instant.
What is it used for?
It is used in APIs, databases, logs, backend systems, programming, date storage and synchronization between systems.
Seconds and milliseconds
Traditional UNIX timestamps use seconds, while many JavaScript platforms use milliseconds. This converter keeps both units separate.
Timestamps and time zones
A timestamp represents the same instant everywhere. The displayed date and time change with the selected IANA time zone, including daylight-saving changes.
What is UTC?
UTC is the coordinated time reference used to compare dates across systems without depending on local time.
Frequently asked questions
Questions about UNIX timestamps
What is a UNIX timestamp?
It is the number of seconds elapsed since January 1, 1970 at 00:00:00 UTC.
How do I convert a timestamp to a date?
Enter the value, choose seconds or milliseconds and select a time zone. The tool displays several formats.
How do I convert a date to a timestamp?
Choose the date, time and time zone. You will get the timestamp in seconds and milliseconds.
What is the difference between seconds and milliseconds?
A millisecond timestamp has three more digits and represents the same date using a unit that is one thousandth as large.
What does timestamp 0 mean?
It represents the Unix Epoch: January 1, 1970 at 00:00:00 UTC.
Does a timestamp have a time zone?
No. It represents an instant in UTC; the time zone only changes how the date is displayed.
Can I use negative timestamps?
Yes, they represent instants before the Unix Epoch when supported by the environment.
Why does the same date change by time zone?
Each zone applies a different offset to the same instant, and some zones also change for daylight saving time.
