Check If Two Dates Differ by More Than a Specified Number of Days in Excel

Comparing dates is one of the most common tasks in Excel.

Whether you're tracking invoice due dates, monitoring project deadlines, checking contract expiration dates, or reviewing shipment schedules, you often need to determine whether the difference between two dates exceeds a certain number of days.

Although Excel makes this possible with functions like IF and ABS, creating the formula correctly can be confusing, especially for users who don't frequently work with date calculations.

With Kutools for Excel's Formula Helper Plus, you can quickly insert a ready-to-use formula that compares two dates against a specified day threshold—without writing the formula yourself.

Why Date Difference Checks Can Be Difficult

Comparing dates isn't simply subtracting one value from another.

In many real-world situations, you need to:

• Compare two dates regardless of their order.
• Determine whether the difference exceeds a specified number of days.
• Return custom results instead of numeric differences.
• Apply the same logic to multiple records.

For example:

Instead of calculating the number of days manually, you simply need to know whether the difference is greater than 30 days.

Limitations of Excel's Built-in Solution

To perform this task in Excel, users often combine:

• IF
• ABS
• TODAY
• Date subtraction

A typical formula looks like this:

While effective, this approach has several drawbacks:

• The formula can be difficult for beginners to understand.
• Multiple arguments must be entered correctly.
• Editing the threshold or return values later can be inconvenient.
• Large worksheets often require copying and maintaining complex formulas.
• Users must remember the correct syntax every time.
