What is a Unix Timestamp and How to Convert It Easily

Updated 2026-08-08 · 4 min read

A Unix timestamp (also called epoch time) is a simple way to represent time as a single number. It counts the seconds that have passed since January 1, 1970, at 00:00:00 UTC, a moment known as the Unix epoch. This system is widely used in programming, databases, and system logs. In this article, we'll explain what a Unix timestamp is, why it's useful, and show you how to convert it using our Unix Timestamp Converter.

Why Do We Use Unix Timestamps?

Computers prefer numbers over text because numbers are easier to store, compare, and calculate. A timestamp like 1710000000 is unambiguous and takes less space than a date string like "2024-03-09 20:00:00 UTC". It also avoids timezone confusion, since the timestamp is always based on UTC.

How to Convert a Unix Timestamp to a Readable Date

Go to our Unix Timestamp Converter.
Enter your timestamp in the "Timestamp to Date" field.
Select whether your timestamp is in seconds or milliseconds.
Click "Convert."
The tool will display the date and time in your local timezone or UTC, depending on your selection.
Copy the result for your use.

Converting a Date to a Unix Timestamp

You can also go the other way: pick a date and time, and the tool will give you the corresponding Unix timestamp. This is handy for scheduling tasks, setting reminders, or logging events in your applications.

Common Timestamp Formats

Seconds: The standard Unix timestamp, often 10 digits.
Milliseconds: Used in JavaScript and many APIs, 13 digits.

If your converted date looks wildly wrong, you might be using the wrong unit. Our tool lets you switch easily.

Frequently Asked Questions

What is the current Unix timestamp?

The current Unix timestamp is the number of seconds since January 1, 1970 UTC. Our tool displays it live on the page, so you always have the latest value.

Why does Unix time start in 1970?

1970 was chosen by early Unix developers as a convenient starting point. It predates most modern computing systems, providing a clean baseline for time measurement.

Is Unix time affected by time zones?

No, Unix timestamps are always based on UTC. When you convert a timestamp to a local date, the tool applies the timezone offset you select.

Can I convert a timestamp on my phone?

Yes, our converter is fully mobile-friendly. You can use it anywhere.

What if my timestamp is in milliseconds?

Simply select 'Milliseconds' in the tool, and it will handle the conversion correctly.
