Unix Timestamp Converter
Convert Unix timestamps to human-readable dates and vice versa. Free online epoch converter with no signup.
What Is a Unix Timestamp Converter?
Unix timestamps are the standard time representation in databases, APIs, log files, and programming languages. Converting between epoch seconds and human-readable dates is a constant need for developers debugging logs, building time-based features, and working with APIs that return timestamps. This bidirectional converter handles both seconds and milliseconds, with timezone support.

Frequently Asked Questions
What is a Unix timestamp?
A Unix timestamp (epoch time) is the number of seconds that have elapsed since January 1, 1970, 00:00:00 UTC. It's a universal way to represent time as a single integer, avoiding timezone and format ambiguity.
What is the difference between seconds and milliseconds?
Unix timestamps are traditionally in seconds (10 digits as of 2026). JavaScript's Date.now() returns milliseconds (13 digits). If your timestamp has 13 digits, divide by 1000 before converting. Confusing the two is one of the most common timestamp bugs.
What is the Year 2038 problem?
32-bit systems store timestamps as a signed 32-bit integer, which overflows on January 19, 2038, at 03:14:07 UTC. After this, timestamps wrap to negative values. 64-bit systems solve this — they won't overflow for 292 billion years.
How do I get the current Unix timestamp?
In JavaScript: Math.floor(Date.now() / 1000). In Python: import time; time.time(). In Bash: date +%s. In SQL: UNIX_TIMESTAMP(). All return the current time as seconds since epoch.
