Unix Timestamp Converter
Convert Unix timestamps in seconds or milliseconds into human-readable calendar dates, or calculate timestamps from any date. 100% private.
How to Use Unix Timestamp Converter
-
View live epoch clock
The live counter displays the current Unix timestamp in seconds and milliseconds in real time.
-
Convert timestamp to date
Paste any epoch timestamp in seconds or milliseconds to see local time, UTC, ISO 8601, and relative time.
-
Convert date to timestamp
Pick any calendar date and time (in your local timezone or UTC) to calculate the exact epoch seconds.
Epoch Timestamp Conversion Example
1729080000UTC: 2024-10-16 12:00:00 UTC | ISO: 2024-10-16T12:00:00.000ZConverts instantaneously with full local and UTC breakdowns.

Frequently Asked Questions
What is a Unix Timestamp (Epoch Time)?
The Unix timestamp is the number of seconds that have elapsed since midnight (00:00:00 UTC) on January 1, 1970, excluding leap seconds. It is the universal standard for storing timestamps in databases and APIs.
How does it detect seconds vs milliseconds?
Unix timestamps in seconds are typically 10 digits long (e.g. 1729080000). Millisecond timestamps (used by JavaScript Date.now()) are 13 digits long. The converter automatically detects both.
What will happen during the Year 2038 problem?
On January 19, 2038, 32-bit signed integers will overflow. Modern 64-bit systems and JavaScript numbers (64-bit float) support dates for hundreds of billions of years into the future without issue.
Is my data private?
Yes! 100% of calculations use standard browser JavaScript Date and Intl APIs. Zero network calls are made.
