Yes, the weekend is over, but another one is just five days away! To make it easier to keep track of Saturdays and Sundays, you can use conditional formatting to highlight weekend dates in Excel.
In this example, the Excel file has a list of product sales for the first half of July. We’d like to highlight the dates and sales numbers that fall on a weekend.
Add Conditional Formatting
To highlight the weekend sales:
- Select all the cells where conditional formatting should be applied, cells H2:J16 in this example. Cell H2 is the active cell in the selection.
- On the Ribbon, click the Home tab, then click Conditional Formatting.
- Click New Rule, to open the New Formatting Rule dialog box
- In the Select a Rule Type list, click Use a formula to determine which cells to format.
- In the Formula box, enter a formula to check the weekday of the date in row 2, which is the active row on the worksheet:
- Click the Format button, and select a Fill colour, or other formatting options, then click OK.
- Click OK to close the New Formatting Rule dialog box.
The weekend rows are highlighted in green.
The WEEKDAY Function
The WEEKDAY function checks the date in column H, and returns a weekday number, based on a numbering system (2) that starts with Monday as 1. Saturday is 6 and Sunday is 7, so we want to highlight weekday numbers that are greater than 5.
Instead of that numbering system, we could have entered 1 or 3 as the second argument (return_type) in the WEEKDAY function.
If we entered a 1, or omitted the second argument, the numbering would start with Sunday as 1. With a 3, Monday would start as 0, and end with a 6 on Sunday.
I used the 2 because that groups Saturday and Sunday at the end of the numbering, and we can simply test for >5.
