How to use unix timestamp converter
- Grab the current timestamp
The live counter at the top updates every second — copy it in seconds or milliseconds any time.

Paste an epoch value, choose seconds or milliseconds, and click Convert to see local time, UTC, ISO 8601 and relative time.
- Convert a date
Pick a date and time to get its Unix timestamp in both seconds and milliseconds.
Features
A ticking counter shows right now's epoch time in seconds and milliseconds, ready to copy.
Timestamp-to-date and date-to-timestamp in one place.
See the standard ISO 8601 string and a human phrase like '2 hours ago' alongside local time and UTC.
Handle the two most common epoch formats.

Frequently asked questions
What is a Unix timestamp?
It's the number of seconds (or milliseconds) since 1 January 1970 UTC, a common way to store time in software.
How do I tell seconds from milliseconds?
Second-based timestamps are usually 10 digits today; millisecond ones are 13 digits. Pick the right unit for accurate results.
Which time zone is shown?
Local time, UTC and ISO 8601 (which is always expressed in UTC, with a 'Z' suffix) are all displayed so you can use whichever your system needs.
What does the relative time mean?
It's a plain-language distance from now — 'in 3 days' for a future timestamp, '2 hours ago' for a past one — useful for sanity-checking a value without doing the date math yourself.
