Unix Timestamp Converter
Convert between Unix timestamps (epoch) and human-readable dates in both directions.
Timestamp → Date
Date → Timestamp
What Is the Unix Timestamp Converter?
The Unix Timestamp Converter turns epoch timestamps into human-readable dates and back again. It auto-detects seconds vs milliseconds, shows your local time, UTC, ISO 8601 and a relative "x minutes ago" value, and converts a chosen date into a timestamp. A one-click button inserts the current time. Everything runs locally.
How It Works
Enter a Unix timestamp (seconds or milliseconds) to see the date in several formats, or pick a date and time to get its timestamp in seconds and milliseconds. Use "Use Current Time" to start from now.
When to Use It
Use it when debugging logs and APIs, working with databases, scheduling, or anywhere systems store time as an epoch number.
Frequently Asked Questions
- Seconds or milliseconds?
- Both. The tool treats 13-digit (or longer) inputs as milliseconds and shorter inputs as seconds.
- Which time zone is shown?
- Both your local time zone and UTC, plus the ISO 8601 string (UTC).
