To calculate weekdays in Excel, you can use the `WEEKDAY` function. The basic syntax is `WEEKDAY(serial_number, [return_type])`. The `serial_number` is the date you're evaluating, and `[return_type]` is optional, dictating the day numbering system you prefer. For instance, using `=WEEKDAY(A1, 2)` returns a number from 1 (Monday) to 7 (Sunday) for the date in cell A1. This function is invaluable for creating schedules, performing date arithmetic, or filtering data by specific days of the week.
