Seconds and milliseconds
Unix timestamps are commonly stored as seconds, while JavaScript often uses milliseconds. The converter accepts either form and displays the corresponding date.
Timestamp Converter
Convert Unix epoch timestamps into readable date formats or turn a selected date and time into a timestamp. Results include local and standardized representations that can be copied individually.

Common uses
- Decode timestamps found in application logs and API responses.
- Create an epoch value for a scheduled event or test fixture.
- Compare local, UTC, ISO 8601, and RFC-style date output.
Timezone awareness
A Unix timestamp represents one instant in UTC. Local date output depends on the timezone configured on your device, so verify the displayed zone when scheduling across regions.
Frequently asked questions
What is the Unix epoch?
It is the reference point at 00:00:00 UTC on January 1, 1970. Unix timestamps count elapsed time from that instant.
Does the tool accept millisecond timestamps?
Yes. You can enter common Unix timestamps in seconds or JavaScript-style timestamps in milliseconds.
Why does the local time differ from UTC?
Local output applies the timezone configured on your device, while UTC output does not apply a local offset.
