Question 1

What is a Unix timestamp (epoch time)?

Accepted Answer

A Unix timestamp is the number of seconds that have elapsed since January 1, 1970 00:00:00 UTC, also called the Unix epoch. It is timezone-independent and used universally by databases, APIs, and operating systems to represent a specific point in time.

Question 2

How do I convert a Unix timestamp to a date?

Accepted Answer

Paste your Unix timestamp into the input. The tool auto-detects whether it is in seconds or milliseconds and shows the UTC date, local date, ISO 8601 string, and how long ago or from now the timestamp is.

Question 3

What is the difference between epoch seconds and epoch milliseconds?

Accepted Answer

Epoch seconds (e.g. 1716850000) count full seconds since the Unix epoch. Epoch milliseconds (e.g. 1716850000000) count thousandths of a second and are used by JavaScript, Java, and many databases. Numbers longer than 11 digits are treated as milliseconds.

Question 4

What is the current Unix timestamp?

Accepted Answer

The current Unix timestamp changes every second. Load this page to see the live counter at the top. You can also get it in a terminal with: date +%s (Linux/Mac) or PowerShell (Get-Date -UFormat %s).

Question 5

What is the maximum Unix timestamp?

Accepted Answer

For 32-bit signed integers, the maximum Unix timestamp is 2147483647, which corresponds to January 19, 2038 03:14:07 UTC — the Y2038 problem. 64-bit systems support timestamps far beyond the year 292 billion.
