Table of Contents :
Converting epoch time to a human-readable date and time format in Excel can seem daunting at first, but with the right guidance, you can easily manipulate and display your data accurately. Epoch time, also known as Unix time, is a system for tracking time that counts the number of seconds that have elapsed since January 1, 1970 (not counting leap seconds). Let’s explore how to convert this time format effectively in Excel.
Understanding Epoch Time ⏳
Epoch time is often used in programming and data storage because it provides a straightforward way to represent time. However, this numerical representation can be hard for most users to interpret. Here’s a brief overview:
- Epoch Time: The number of seconds since January 1, 1970.
- Format: It’s typically displayed as an integer (e.g., 1633036800).
For example, an epoch time of 1633036800 corresponds to October 1, 2021 at 00:00:00 GMT.
Converting Epoch Time in Excel 🔄
To convert epoch time into a readable date and time in Excel, follow these steps:
-
Input your Epoch Time: Enter your epoch time in a cell (for example, A1).
-
Conversion Formula: In another cell, use the following formula:
=A1/86400 + DATE(1970,1,1)- Explanation:
- Dividing the epoch time by
86400converts seconds to days (since there are 86400 seconds in a day). - Adding
DATE(1970,1,1)establishes the starting point of the Unix time.
- Dividing the epoch time by
- Explanation:
-

Important Note: Ensure your Excel settings are set to recognize dates correctly, as regional settings may affect the output format.
Adjusting for Time Zones 🌐
If you need to account for time zones, you can adjust your formula by adding or subtracting hours:
- For GMT+2:
=A1/86400 + DATE(1970,1,1) + (2/24) - For GMT-5:
=A1/86400 + DATE(1970,1,1) - (5/24)
This adjustment will display the correct local time corresponding to the epoch time.
Conclusion 🎉
Converting epoch time to a human-readable format in Excel is not only possible, but it’s also straightforward with the right formulas and knowledge. With just a few steps, you can transform numerical timestamps into date and time values that make sense to you and your audience. By mastering these conversions, you can effectively manage and analyze time-based data within your spreadsheets. Happy Excel-ing!
