How Unix time works
Unix time counts elapsed time from 1970-01-01 00:00:00 UTC, usually in seconds or milliseconds.
- 10-digit values are usually seconds
- 13-digit values are usually milliseconds
- Milliseconds = seconds x 1000
Time Converter
Unix Timestamp to Date Converter
Turn raw Unix timestamps into readable dates when you are checking logs, API payloads, database rows, webhook retries, or analytics events.
Convert Unix timestamps in seconds or milliseconds
How to use the Unix timestamp to date converter
1
Paste a Unix timestamp in seconds or milliseconds, such as a value copied from logs, an API response, or a database row.
2
Read the converted date right away and adjust the number if you want to compare nearby events or check whether the value is in seconds or milliseconds.
3
Use the result to debug webhooks, scheduled jobs, auth expirations, analytics events, or any workflow where the raw timestamp is hard to read.
Example timestamp checks
1714521600
2024-05-01 00:00:00 UTC
A 10-digit value is commonly a Unix timestamp in seconds.
1714521600000
2024-05-01 00:00:00 UTC
The same moment expressed in milliseconds has three extra zeros.
Debugging notes
- If the output is decades off, check whether the source uses seconds or milliseconds.
- Unix timestamps represent a moment in UTC; display time depends on locale and time zone.
- JavaScript Date values usually use milliseconds, while many backend APIs store seconds.
Make sense of raw Unix timestamps at a glance
Useful for logs and API responses
Good when backend logs, webhook payloads, or database fields only show a raw Unix timestamp.
Easy to spot time issues fast
Change the number and see the readable date update immediately while you compare events or debug a time mismatch.
Works with seconds and milliseconds
Handles common 10-digit and 13-digit Unix timestamps so it is easier to catch unit mistakes.
Useful during live debugging
Useful when you need to verify callback times, queue events, or log entries while debugging an issue.

Unix timestamp to date FAQ
Does this tool support both seconds and milliseconds?
Yes. You can enter common 10-digit second timestamps and 13-digit millisecond timestamps directly without extra formatting.
Why does a timestamp sometimes look completely wrong?
The most common reason is mixing seconds and milliseconds. If the output looks decades off, the original value is probably using the other unit.
Why does the converted date sometimes look decades off?
That usually means the source value is in the other precision. A seconds value treated as milliseconds, or a milliseconds value treated as seconds, can shift the result by decades.
Need to keep working with time data?
Switch to date-to-Unix or time zone tools when the next step is encoding a time or comparing it across regions.
