Unix Time Calculator



Unix time, also known as Epoch time, is a system for tracking time in computing. It represents the number of seconds that have elapsed since 00:00:00 Coordinated Universal Time (UTC) on January 1, 1970, not counting leap seconds. A Unix time calculator is a handy tool for converting conventional date and time into Unix time and vice versa.


The formula to convert a regular date and time to Unix time is:

Unix Time=Total Seconds from Epoch 

The total seconds from the epoch are calculated by adding the seconds elapsed in the given date, hours, minutes, and seconds.

How to Use?

Using a Unix time calculator is a straightforward process:

  1. Input Date and Time: Enter the date and time you want to convert into Unix time.
  2. Convert to Unix Time: Press the calculate button to obtain the Unix time corresponding to the provided date and time.
  3. Convert Unix Time to Regular Time: Some calculators also allow you to convert Unix time back into a human-readable date and time format.


Let’s consider an example:

  • Date and Time: October 15, 2023, 12:30:00 PM

Unix Time=Total Seconds from Epoch 

Unix Time=1634284200

So, the Unix time for October 15, 2023, at 12:30:00 PM is 1634284200.


Q1: Why is January 1, 1970, the starting point for Unix time?

A1: January 1, 1970, is the Unix epoch because it was a convenient starting point, and using UTC (Coordinated Universal Time) avoids time zone discrepancies.

Q2: Can Unix time be negative?

A2: No, Unix time is always a non-negative value. It starts at 0 on January 1, 1970, and increments from there.

Q3: How can I convert Unix time to a readable date and time?

A3: Many online tools and programming libraries provide functions to convert Unix time to a human-readable date and time format.


The Unix time calculator is a valuable tool for developers, system administrators, and anyone working with timestamps in computing. Understanding how to convert between Unix time and regular date and time formats can be essential for troubleshooting, debugging, and coordinating events in the digital world. Whether you’re working with historical data or planning future events, the Unix time calculator simplifies time-related calculations and conversions.
