How to use
1. Convert a Unix timestamp to a date
Enter the number and choose seconds or milliseconds. The converter shows UTC, your local timezone, and ISO 8601. It does not guess the unit from the number of digits.
2. Convert a date to a Unix timestamp
Pick a local date and time. The output is Unix seconds and Unix milliseconds.
3. Use the current time
Current timestamp shows now in both units. Copy any value you need. All work stays in the browser.
Examples
Unix epoch
0 seconds is 1970-01-01 00:00:00 UTC, the Unix epoch.
Seconds versus milliseconds
1516239022 seconds is 2018-01-18T01:30:22.000Z. The same digits as milliseconds are a different, earlier instant. Choose the unit explicitly.
Frequently asked questions
- What is a Unix timestamp?
- A Unix timestamp (epoch time) is the number of seconds — or sometimes milliseconds — since 1970-01-01T00:00:00Z.
- Does this epoch converter upload my values?
- No. Conversion uses the browser Date API only.
- Which timezone is “local”?
- Local means your current browser timezone. UTC and ISO 8601 are timezone-independent.
