## What is the WEEKDAY function in Excel?

The WEEKDAY function in Excel is used to return the day of the week corresponding to a particular date. It is a part of the Date and Time functions in Excel.

The syntax for the WEEKDAY function is:

=WEEKDAY(serial_number,[return_type])

Where:

• serial_number is the date for which you want to find the day of the week. This argument can be entered directly as a date value (e.g., “5/4/2023”) or as a reference to a cell containing a date value.
• return_type: This is an optional argument that specifies the type of return value. If omitted, the default value is 1. The return_type can take one of the following values:
• 1 (default) – Returns numbers from 1 (Sunday) to 7 (Saturday)
• 2 – Returns numbers from 1 (Monday) to 7 (Sunday)
• 3 – Returns numbers from 0 (Monday) to 6 (Sunday)
• 11 – Returns text values of the day of the week (e.g., “Sunday,” “Monday,” etc.)

The WEEKDAY function is particularly useful when you need to calculate data based on the day of the week 🧐

For example, you could use it to create a pivot table that shows the average sales for each day of the week. Or you can use it to calculate the number of days until the next weekend.
