Function should give output in number format, however if output is not as per the desired format then we need to change the cell format to “GENERAL”. We will be discussing the steps that how we can change the cell format to GENERAL in detail.
If input value is not in date format then the output of the function will return to “#VALUE!”. So always ensures that the input data range is in correct format to get the appropriate results/output.

Syntax Description:
There are two arguments i.e. serial_number and return_type. Below are the details of each arguments:
serial_number argument, is used to give cell reference where date is mentioned and weekday to be counted.
return_type [Optional] argument, is a optional argument is used to give reference to selection of week period. by default it takes “Sunday to Saturday” as a week and counts Sunday as 1st Day till Saturday as 7th Day, however if week period is different than “Sunday to Saturday” return type argument can be used.
Below is the list of return_type and explanation:
Example 1: Calculate Weekday for a Date applying default “return_type” argument.
Suppose we have a date i.e. Monday, 23rd March 2020 and need to identify what is count of week for the said date. We will be using the default week i.e. Sunday to Saturday while applying the function.
Explanation: We can see the output of the function returns as 2. Because while considering a week of Sunday to Saturday, Sunday is 1st day and Monday is 2nd Day.
Example 2: Calculate Weekday for a Date applying 2 as “return_type” argument.
With the same date i.e. Monday, 23rd March 2020 and need to identify what is count of week for the said date. We will be considering “return type = 2” i.e. Monday to Sunday while applying the function.
Explanation: We can see the output of the function returns as 1. Because while considering a week of Monday to Sunday, Monday is 1st day.
Example 3: Evaluating a date with ALL as “return_type” argument.
Here we are evaluating a date i.e. Monday, 23rd March 2020 with All “return type” argument
Explanation: We can see the output of the function with various “return_type” returns value between 0 to 7.
