What is a Unix timestamp?

A Unix timestamp is the number of seconds elapsed since January 1, 1970, 00:00:00 UTC (called the Unix epoch). It's a single number representing any point in time, independent of timezone.

What is the difference between seconds and milliseconds timestamps?

Unix timestamps in seconds are standard (10 digits as of 2024). Millisecond timestamps (used in JavaScript's Date.now()) are 1000x larger (13 digits). Use seconds for most systems; milliseconds for JavaScript.

What is the maximum Unix timestamp?

The 32-bit signed integer max is 2,147,483,647 = January 19, 2038, 03:14:07 UTC (the "Year 2038 problem"). 64-bit timestamps can represent dates billions of years into the future.

What timezone are Unix timestamps in?

Unix timestamps are always in UTC (Coordinated Universal Time). They represent the same moment regardless of what timezone you're in. The local time display depends on your browser's timezone setting.

How do I get the current Unix timestamp in JavaScript?

Math.floor(Date.now() / 1000) for seconds, or Date.now() for milliseconds. In Python: import time; int(time.time()). In PHP: time().

About Unix Timestamp Converter

Convert Unix timestamps (epoch time) to human-readable dates and times, and vice versa. Unix timestamp is the number of seconds elapsed since January 1, 1970, 00:00:00 UTC (the Unix epoch). It's widely used in programming, databases, APIs, and system logs.

Our converter handles both seconds and milliseconds (used in JavaScript), shows the timestamp in multiple timezone formats, and lets you convert any date to its corresponding Unix timestamp. This is an essential tool for developers debugging API responses, analyzing logs, working with database timestamps, and understanding cron job schedules.

The current Unix timestamp is shown at the top and auto-updates every second — useful when you need the current timestamp for testing.
