Excel is a powerful tool for organizing and analyzing data, but it can also be used to perform various calculations. One of the calculations you can do with Excel is to calculate weekdays. This is a useful function to have when working with dates or times, as it can quickly tell you how many days are in between two dates or how many weekdays are in a given month.

The WEEKDAY formula is the Excel function used to calculate weekdays. The syntax for this formula is =WEEKDAY(start_date, [end_date]), where start_date is the date you want to calculate from and end_date is the date you want to calculate to. The formula will return an integer between 1 and 7, which corresponds to a day of the week (1- Monday, 2- Tuesday, etc.).

For example, if you want to calculate the number of weekdays between June 1, 2020 and July 31, 2020, you would use the following formula: =WEEKDAY(6/1/2020, 7/31/2020). This would return the result of 45, as there are 45 weekdays between the two dates.

You can also use the WEEKDAY formula to calculate the weekday of a specific date. To do this, you would just need to enter the date once in the formula, like so: =WEEKDAY(6/1/2020). This would return the result of 3, indicating that June 1st is a Tuesday.

In conclusion, the WEEKDAY formula is a great tool for calculating weekdays in Excel. Whether you're trying to figure out how many weekdays are in a certain period of time or just want to know the name of the day for a specific date, this formula can help you save time and get the job done quickly.
