About the Timestamp Converter
This Unix timestamp converter turns epoch time, the number of seconds or milliseconds elapsed since January 1, 1970 UTC, into readable calendar dates and back again. It automatically detects whether a pasted value is in seconds or milliseconds by counting its digits, so you can convert timestamp to date output straight from an API response, database column, or log file without guessing the unit first.
The reference table below lists common time durations in seconds, handy when writing cache expirations, cron intervals, or session timeouts.
| Duration | In Seconds |
|---|---|
| 1 minute | 60 seconds |
| 1 hour | 3,600 seconds |
| 1 day | 86,400 seconds |
| 1 week | 604,800 seconds |
| 30 days | 2,592,000 seconds |
| 365 days | 31,536,000 seconds |
How to Use This Tool
- Watch the live current Unix timestamp update every second in both seconds and milliseconds.
- To convert a timestamp, paste it into the Timestamp to Date field. The unit is detected automatically from its digit count.
- Read the resulting ISO 8601, UTC, and local timezone dates, and use the copy button next to any value.
- To go the other way, pick a date and time in the Date to Timestamp field to get its epoch seconds and milliseconds.
Why Use This Timestamp Converter
Automatic Unit Detection
No need to specify seconds or milliseconds, the tool figures it out from the number of digits you paste.
Two-Way Conversion
Convert epoch time to a date, or a date back to epoch time, from the same page.
Who Should Use This
- Backend developers debugging API responses or database columns stored as epoch time.
- Support engineers translating log timestamps into readable dates during incidents.
- QA testers generating specific epoch values to reproduce time-based bugs.
- Data analysts converting exported timestamp columns into calendar dates.
Privacy First
Every conversion happens locally using your browser's built-in JavaScript date engine. No timestamp, date, or value you enter is ever transmitted to a server or stored anywhere.
