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 weekdays (weekends excluded) between two dates.

1. The NETWORKDAYS function below returns 11. There are 11 weekdays 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.

2. If you supply a list of holidays, the NETWORKDAYS function returns the number of workdays (weekends and holidays excluded) between two dates.

WORKDAY

The WORKDAY function in Excel returns the date before or after a specified number of weekdays (weekends excluded).

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.

Fill Weekdays

1. For example, enter the date 12/17/2025 into cell A1.

2. Select cell A1 and drag the fill handle down. AutoFill automatically fills in the days.
