Epoch time converter
Epoch time counts from January 1, 1970 UTC. This converter turns that number into a readable datetime and helps you spot whether the source value is seconds or milliseconds.
Examples for this search
10-digit epoch values are usually seconds.
13-digit epoch values are usually milliseconds.
The timezone changes the display, not the underlying instant.
Toolvert detects milliseconds when the absolute value is at least 1,000,000,000,000. Smaller values are treated as seconds. The result is formatted with the browser Intl API.
What this unix timestamp converter does
Use this Unix timestamp converter when a log, database row, event payload, or analytics export stores time as an epoch number. Paste the number to turn it into a readable date in the timezone you choose.
Common use cases
- Decode event timestamps from product analytics or tracking payloads.
- Read Unix timestamps stored in database rows, queues, cache keys, and log lines.
- Check whether an API uses seconds or milliseconds for a date field.
- Explain a timestamp to a teammate without doing mental timezone math.
Accepted input formats
1785681000
1785681000000
America/Los_Angeles, America/New_York, UTC
How it works
Toolvert detects milliseconds when the absolute value is at least 1,000,000,000,000. Smaller values are treated as seconds. The result is formatted with the browser Intl API.
Common mistakes
- If the date appears around 1970, you probably pasted milliseconds into a seconds-only converter.
- If the date appears far in the future, you may be treating seconds as milliseconds.
- Timestamps do not contain a timezone; the timezone only affects how the same instant is displayed.
Frequently asked questions
How do I know if a timestamp is seconds or milliseconds?
Unix timestamps with 10 digits are usually seconds. JavaScript timestamps with 13 digits are usually milliseconds.
Does a Unix timestamp store timezone information?
No. It represents an instant in time. The selected timezone only changes the displayed date.
Can I convert negative timestamps?
Yes, if the browser can represent the date. Negative timestamps refer to dates before January 1, 1970 UTC.
