7 Ways To Calculate Date Difference Excluding Weekends In Excel

Calculating date differences in Excel is a common task, especially for those who manage schedules, track project timelines, or analyze data that requires excluding weekends. The need to calculate the number of working days between two dates without counting Saturdays and Sundays can be quite challenging if you're not familiar with the right Excel functions. 🗓️

In this guide, we'll explore seven effective methods to calculate the date difference excluding weekends in Excel, along with tips, shortcuts, and advanced techniques to help streamline your workflow. Let's dive in!

1. Using the NETWORKDAYS Function

The most straightforward way to calculate the number of working days between two dates is by using the NETWORKDAYS function. This built-in Excel function automatically excludes weekends and can also account for holidays if specified.

Syntax

=NETWORKDAYS(start_date, end_date, [holidays])

Example

Let's say you want to find the number of working days between January 1, 2023, and January 10, 2023:

=NETWORKDAYS("2023-01-01", "2023-01-10")

Important Note: If you want to include holidays, you can specify them as a range in the third argument.

2. Using the NETWORKDAYS.INTL Function

If your weekends don't follow the usual Saturday-Sunday pattern, you can use the NETWORKDAYS.INTL function. This function allows you to specify which days are considered weekends.

Syntax

=NETWORKDAYS.INTL(start_date, end_date, [weekend], [holidays])

Example

To calculate working days between the same dates but considering Friday and Saturday as weekends:

=NETWORKDAYS.INTL("2023-01-01", "2023-01-10", 7)

The 7 indicates Friday and Saturday as the weekend.

3. Calculating Manually Using a Formula

If you'd rather use a manual method rather than built-in functions, you can achieve this with a combination of basic arithmetic and the WEEKDAY function.

Formula

= (end_date - start_date + 1) - (2 * (INT((end_date - start_date + WEEKDAY(start_date, 2) - 1)/7)))

Example

To find working days between January 1, 2023, and January 10, 2023:

= (10 - 1 + 1) - (2 * (INT((10 - 1 + WEEKDAY(1, 2) - 1)/7)))

This formula calculates the total days and then subtracts weekends.

4. Utilizing Conditional Formatting

If you want a quick visual indication of which dates are working days versus weekends, you can use conditional formatting.

Steps

1. Select the range of dates.
2. Go to the Home tab.
3. Click on Conditional Formatting > New Rule > Use a formula to determine which cells to format.
4. Enter the formula:

=WEEKDAY(A1, 2) > 5

5. Choose a format and click OK.

This will highlight weekends in your selected range.

5. Creating a List of Holidays

Adding a list of holidays can help refine your calculations. Create a separate list in your Excel sheet and use that list in your NETWORKDAYS functions.

Steps

1. List your holidays in a column (e.g., Column D).
2. Reference this range in your function:

=NETWORKDAYS(A1, B1, D1:D5)

This will ensure holidays are excluded from your working days count.
