5 Easy Ways To Convert Date Numbers To Dates In Excel

If you've ever worked with Excel, you might have come across date numbers—those pesky serial numbers that Excel uses to represent dates. Instead of seeing an easily readable date like “March 10, 2023”, you might find yourself staring at the number “45062”. While this format can be useful for computations, it can be frustrating when you just want to see the date! 😩 But don’t worry; I’m here to guide you through five easy ways to convert these date numbers to dates in Excel. Let’s make that date number more friendly!

Understanding Excel's Date System

Before diving into the methods, it's crucial to understand how Excel handles dates. Excel uses a system where it counts the number of days since a base date. For most Excel versions, that base date is January 1, 1900. Therefore, the date number “1” represents January 1, 1900, while “45062” corresponds to March 10, 2023. This understanding will help you appreciate why these methods work.

Method 1: Formatting Cells as Dates

The simplest way to convert date numbers into recognizable dates is by formatting the cells. Here’s how:

1. Select the Cell(s): Click on the cell that contains the date number (e.g., 45062).
2. Open Format Cells: Right-click the selected cell and choose “Format Cells”.
3. Choose Date: In the Format Cells window, click the “Number” tab, then select “Date” from the list on the left.
4. Pick a Format: Choose your preferred date format (for example, "March 14, 2012" or "3/14/12").
5. Click OK: Hit OK, and voilà! The date number is now displayed as a standard date.

Method 2: Using the TEXT Function

The TEXT function can convert date numbers into dates formatted as text. Here’s how to use it:

1. Select a New Cell: Click on an empty cell where you want the converted date to appear.
2. Enter the Formula: Type =TEXT(A1, "mm/dd/yyyy"), replacing “A1” with the cell that contains your date number.
3. Hit Enter: Press Enter, and the cell will now show the date.

Method 3: Adding a Date Offset

Sometimes, you might want to quickly convert a date number without changing the format of the original cell. Here’s a straightforward way to do this:

1. Use a Simple Formula: In a new cell, type =A1 + 0 (assuming A1 contains your date number).
2. Format the Result: Apply the “Date” format as described in Method 1.

This method simply adds zero to the date number, which forces Excel to treat it as a date.

Method 4: Using the DATE Function

If your date number is a little more complex, you might want to use the DATE function. Here’s the process:

1. Break Down the Number: Identify the year, month, and day from your date number.
2. Enter the DATE Function: For example, if A1 contains 45062, your formula would look like this:

   =DATE(2023, 3, 10)
   

3. Press Enter: This will directly yield the date you're looking for.

Method 5: Using Power Query

For those who prefer a more advanced approach, Power Query can be a great way to convert date numbers to dates—especially for larger datasets.

1. Load Data into Power Query: Select your data and go to the “Data” tab, then click “From Table/Range”.
2. Select the Column: Once in Power Query, select the column containing your date numbers.
3. Change Data Type: In the “Transform” tab, find the “Data Type” dropdown and select “Date”.
4. Close and Load: Hit “Close & Load” to bring the converted dates back into Excel.

This method is particularly useful when you have to deal with a huge volume of data, as it automates the conversion process.

Common Mistakes to Avoid

As you get familiar with converting date numbers in Excel, here are a few common mistakes to steer clear of:

1. Not Formatting Cells: Failing to format the cell as a date will lead to confusion, as Excel may display a number.
2. Using Incorrect Functions: Make sure you’re using the correct functions to manipulate date data.
3. Ignoring Locale Settings: Your computer’s regional settings can affect date formats. Make sure it aligns with your needs.

Troubleshooting Issues

If you're facing problems converting date numbers, consider these troubleshooting tips:

• Check Cell Format: If it’s still not displaying correctly, double-check that the cell format is set to “Date”.
• Verify Date Numbers: Ensure that your date numbers are valid and within Excel’s date range.
• Adjust Regional Settings: If you’re getting unexpected results, it may be time to look at your Excel regional settings under File > Options > Language.
