Excel Date Confusion: Why Is It Showing As A Number?

When you first start using Excel, one of the common frustrations that many beginners encounter is the date confusion, particularly when dates appear as numbers instead of the lovely date format we expect. 😖 Understanding why this happens can save you a lot of time and help you avoid mistakes that can throw your entire spreadsheet off course. Let’s dive deep into this topic and explore some helpful tips, shortcuts, and advanced techniques for using dates in Excel effectively.

Understanding Excel's Date System

Excel uses a specific date system, where dates are actually stored as sequential serial numbers. The default starting date (or “zero date”) in Excel is January 1, 1900. As days go by, the numbers increase, and therefore, if you input a date without proper formatting or accidentally change the format, Excel will display it as a serial number instead of your expected date.

For instance:

• January 1, 1900 is 1
• January 2, 1900 is 2
• January 1, 2023 is 44927

This can create a frustrating situation when you just want to see a neatly formatted date. Fortunately, fixing this is usually straightforward.

Common Scenarios Where Dates Show as Numbers

Entering Dates Incorrectly

When you input a date as a number (like "123" instead of "01/23/2023"), Excel may interpret it as just that—a number! Here’s how to tackle that:

1. Format as Date: Select the cell, then go to Home > Number and choose Short Date or Long Date from the dropdown.
2. Use a Slash: Always use slashes (/) or dashes (-) to separate the day, month, and year when typing dates.

Importing Data

Sometimes, when you import data from another source like CSV files, dates might not get interpreted correctly. Here’s what you can do:

1. Text to Columns: Use the Text to Columns feature to split the cells correctly:
   • Select your column of dates.
   • Go to Data > Text to Columns.
   • Choose Delimited, click Next, and select the delimiter (if applicable).
   • Choose Date and select the format (MDY, DMY, etc.).
   • Click Finish.

Formatting Issues

If Excel shows the date as a number due to incorrect formatting, follow these steps:

1. Select the Cell: Click on the cell that’s showing the date as a number.
2. Change Format: Right-click, select Format Cells, then under the Number tab, choose Date.
3. Select the Date Style: Pick your preferred date style and click OK.

Here’s a quick overview of common Excel date formatting:

<table> <tr> <th>Date Format</th> <th>Example</th> </tr> <tr> <td>Short Date</td> <td>1/23/2023</td> </tr> <tr> <td>Long Date</td> <td>Monday, January 23, 2023</td> </tr> <tr> <td>Custom Format</td> <td>23-Jan-2023</td> </tr> </table>

Tips and Tricks for Working with Dates in Excel

Use Keyboard Shortcuts

There are several handy shortcuts that can speed up your workflow when working with dates:

• Ctrl + ;: Inserts the current date.
• Ctrl + Shift + ;: Inserts the current time.

Use Functions for Date Calculations

If you want to perform calculations with dates (like finding the difference between two dates), Excel has some useful functions:

• DATEDIF: Finds the difference between two dates.
• EDATE: Returns the date that is a specified number of months before or after a given date.
• EOMONTH: Returns the last day of the month that is a specified number of months before or after a start date.

Avoiding Common Mistakes

1. Using Text Instead of Date: Always ensure you're entering dates in a recognizable format.
2. Mixing Formats: Ensure that your entire column of dates is formatted the same to prevent confusion.

Troubleshooting Common Issues

Here are some common troubleshooting steps if your dates are still showing up incorrectly:

• Cell Format: Double-check that the cell format is set to date.
• Re-enter Dates: If dates still show as numbers, try re-entering them in the correct format.
• Excel Options: Sometimes, your Excel settings can impact how dates are displayed. Go to File > Options > Advanced and check your date settings.
