### WEEKDAY

The WEEKDAY function in Excel returns a number from 1 (Sunday) to 7 (Saturday) representing the day of the week of a date.

1. The **WEEKDAY function** below returns 2. 12/22/2025 falls on a Monday.

2. You can also use the TEXT function to display the day of the week.

3. Or create a custom date format (dddd) to display the day of the week. Cell A1 still contains a date.

### NETWORKDAYS

The NETWORKDAYS function in Excel returns the number of workdays between two dates. NETWORKDAYS excludes weekends (Saturday and Sunday).

1. The NETWORKDAYS function below returns 11. There are 11 workdays between 12/17/2025 and 12/31/2025.

Explanation: the NETWORKDAYS function includes the start date and the end date. The calendar below helps you understand this formula. Simply count the number of circles.

### NETWORKDAYS.INTL

Use NETWORKDAYS.INTL instead of NETWORKDAYS to specify different weekend days. Use a string of 0's and 1's (third argument) to specify which days are weekend days.

1. The NETWORKDAYS.INTL function below returns 8.

Explanation: the first 0 tells Excel that Monday is not a weekend day. The second 0 tells Excel that Tuesday is not a weekend day, etc. In this example, Friday, Saturday and Sunday are weekend days. The calendar below helps you understand this formula.

2. Enter the WORKDAY.INTL function shown below.

### Highlight Weekdays

You can use conditional formatting in Excel to highlight dates that are weekdays (Monday, Tuesday, Wednesday, Thursday or Friday).

1. For example, select the range A1:A8.

2. On the Home tab, in the Styles group, click Conditional Formatting.

3. Click New Rule.

4. Select 'Use a formula to determine which cells to format'.

5. Enter the formula =AND(WEEKDAY(A1)>1,WEEKDAY(A1)<7)

6. Select a formatting style and click OK.

Result. Excel highlights all weekdays.

Explanation: always write the formula for the upper-left cell in the selected range. Excel copies the formula to the other cells. Use the formula =OR(WEEKDAY(A1)=1,WEEKDAY(A1)=7) to highlight weekend dates.
