Convert Unix Timestamp to Readable Date
You see 1713427200 in a database or API response. What date is that? Unix timestamps are everywhere in programming. Let me help you read them.
Quick Answer
A Unix timestamp is the number of seconds since January 1, 1970. Convert it to a human date instantly with the free tool at dotsapps.com. 1713427200 = April 18, 2024.
What Is a Unix Timestamp (Epoch Time)
A Unix timestamp counts the seconds since January 1, 1970, 00:00:00 UTC. That starting point is called the Unix epoch.
Right now, the timestamp is over 1.7 billion. Every second, it goes up by one. It is a simple, universal way to track time. No time zones. No date formats. Just a number.
Databases, APIs, log files, and programming languages all use Unix timestamps because they are easy to compare and sort.
How to Read a Unix Timestamp
A 10-digit number like 1713427200 is in seconds. A 13-digit number like 1713427200000 is in milliseconds. JavaScript uses milliseconds. Most other systems use seconds.
To convert by hand, you would divide by 86400 (seconds per day) and count days from 1970. But nobody does that. Just paste it into a converter.
The converter shows you the date in your local time zone and in UTC. This matters because the same timestamp means different clock times in New York and Tokyo.
Converting Dates to Unix Timestamps
Going the other direction is just as common. You need to store a date in a database and want the timestamp.
Enter a date like April 18, 2024 and get back 1713427200. Simple.
In code, most languages have built-in functions: Date.now() in JavaScript, time() in PHP, time.time() in Python.
The Year 2038 Problem
Many older systems store timestamps as 32-bit signed integers. The maximum value is 2,147,483,647, which equals January 19, 2038 at 03:14:07 UTC.
After that, these systems would overflow and jump to a date in 1901. This is the Y2K problem for Unix systems.
Modern 64-bit systems handle timestamps far into the future. But legacy systems still need updating. It is a real concern for embedded devices and old databases.

Frequently Asked Questions
What is the current Unix timestamp?
The current Unix timestamp changes every second. Open the converter tool to see it live. As of mid-2024, it is around 1.71 billion.
Why do Unix timestamps start at 1970?
The original Unix operating system was created in the late 1960s. The developers chose January 1, 1970 as a simple, round starting point. The choice was arbitrary but it stuck.
What is the difference between seconds and milliseconds timestamps?
A seconds timestamp has 10 digits (like 1713427200). A milliseconds timestamp has 13 digits (like 1713427200000). JavaScript and Java use milliseconds. Most other systems use seconds.
Can Unix timestamps be negative?
Yes. Negative timestamps represent dates before January 1, 1970. For example, -86400 is December 31, 1969. Most systems support this, but some do not.
