About the Unix Timestamp Converter
A Unix timestamp (or epoch time) is the number of seconds that have elapsed since January 1, 1970 UTC. It's a language-independent way to store and compare points in time, used throughout databases, APIs, and log files — but it isn't human-readable on its own.
This converter turns Unix timestamps into readable local and UTC dates, and converts human dates back into timestamps. It supports both seconds and milliseconds and updates the current epoch live.
Features
- Convert epoch timestamps to local, UTC, and ISO 8601 dates
- Convert any date back to seconds or milliseconds
- Auto-detects seconds vs milliseconds
- Live current-epoch clock
How to use
- Paste a timestamp to see the equivalent date.
- Or enter a date to get its Unix timestamp.
- Copy the format you need.
Frequently asked questions
Seconds or milliseconds?
Unix time is traditionally in seconds, but JavaScript and many APIs use milliseconds. This tool auto-detects based on the number's length (13+ digits is treated as milliseconds).
Why is the date different from mine?
Timestamps are timezone-independent. The tool shows both your local time and UTC so you can compare.
