Apply Date Format in Excel

The Date format in Excel allows you to display numeric values as dates. This is useful for tracking deadlines, scheduling tasks, or analyzing data over time.

How to Apply Date Format

1. Select the cells containing the numbers or dates you want to format
2. Go to the Home tab → Number group
3. Click the dropdown and select Date
4. Optionally, choose a date format style (e.g., 14-Mar-2025, 3/14/2025)

Tips & Best Practices

• Ensure your numeric values represent valid Excel dates (Excel counts dates from Jan 1, 1900)
• Use custom date formats for reporting (e.g., "dddd, mmmm dd, yyyy")
• Combine with Conditional Formatting to highlight upcoming deadlines or past dates

FAQ

Q: Can I change the date format after applying it?

Q: What happens if the number is not a valid date?

Excel will display a series of #### symbols or incorrect dates. Ensure the number corresponds to a valid date.
