Excel WEEKDAY Function: Syntax & Arguments
Firstly, we’ll see the syntax and argument of the function. If you insert the function after entering equal sign (=), you’ll see the following figure.
Returns the day (in numbers) of the week with respect to a given date. In the default configuration, the day is represented as an integer with values ranging from 1 (Sunday) to 7 (Saturday).
0 to 7 (in numbers)
|Argument||Required or Optional||Value|
|serial_number||Required||A number representing the day from which you want to find the day of the week|
|return_type||Optional||A number determining the return value type|
- Dates are stored in Microsoft Excel as consecutive serial numbers, which allows them to be used in calculations. Besides, dates should be inserted as the date format or using the DATE function. There may be problems if the dates are inserted in text format.
- Return_type is an argument in the WEEKDAY function which specifies the first day of the week. If you omit to input any return_type, the WEEKDAY function returns 1 for Sunday and 7 for Saturday (by default). Return type 11-17 is introduced in Excel 2010 version.
|return_type||First day||Numerical result||Start-end|
|1 or omitted (default)||Sunday||1-7||Sunday-Saturday|
|3||Tuesday||0-6 (since Monday = 0 in this case)||Monday-Sunday|

Example 6: WEEKDAY Function to Get Weekdays and Weekends
If you want to determine the weekdays and weekends for a given date, you may utilize the formula.

Usually, the rate of payment is higher for weekends. If the number of working hours is given, you need to calculate the payment for each employee and the total payment for all employees.
The formula will be-
=IF(WEEKDAY(C5, 2)>5, D5*$H$6,D5*$H$7)
Then use the SUM function for aggregating the individual payment.
