## How to Subtract a Date from Today in Excel

This guide will walk you through the steps needed to subtract a specific date from today’s date in Excel. By the end, you’ll have a functional formula that updates automatically and helps you manage your time more effectively. Let’s get started!

### Step 1: Open Excel

First, open Microsoft Excel on your computer. If you don’t have it installed, you can download it from the official Microsoft website.

Ensure you have a new or existing worksheet where you want to perform the calculations.

### Step 2: Enter the Date to Subtract

This date will be the fixed date against which you measure the difference.

This cell will display the number of days between the two dates.

### Step 4: Use the Formula

This formula calculates the number of days between today and the date in cell A1.

### Step 5: Press Enter

After typing the formula, press the Enter key on your keyboard to see the result.

Excel will now display the number of days between today and the date you entered in cell A1.

After completing these steps, Excel will automatically calculate the difference between today’s date and the date you provided, displaying the result in the chosen cell.

## Tips for Subtracting a Date from Today in Excel

• Format the Date Correctly: Make sure the date in cell A1 is in a recognizable date format (e.g., MM/DD/YYYY).
• Auto-updating: The `=TODAY()` function auto-updates every day, so your result will always be current.
• Negative Values: If the date in A1 is in the future, you’ll get a negative value indicating days remaining.
• Custom Formatting: Use custom formatting if you want the result in months or years instead of days.
• Error Checking: Double-check your cell references to ensure the formula points to the correct date cell.

### Can I subtract months or years instead of days?

Yes, you can use the `DATEDIF` function with different units (e.g., "m" for months, "y" for years).

### Why is my formula returning an error?

Ensure that the date you entered is valid and formatted correctly. Also, check for any typos in the formula.

### What if I want the result in hours or minutes?

You can achieve this by multiplying the days by 24 (for hours) or 1440 (for minutes).

### Can I subtract today’s date from multiple dates at once?

Yes, you can drag the fill handle of the cell with the formula to apply it to adjacent cells.

### Do I need to manually update the formula every day?

No, the `=TODAY()` function auto-updates, so your subtraction results will always be up-to-date.

## Summary
