**WEEKDAY Function Syntax Representation**

serial_number – the value for this argument is a chronological number that signifies the date of the day that you would like to find. The value of the date must be obtained from the DATE function or as a result from other functions or formulas. An example of date that is entered as DATE function is “=DATE(2011,1,3)”, which means, January 3, 2011.

There are certain details to remember once the dates are not entered as a value from the DATE function, but rather as text and they are as follows:

- Microsoft Excel stores date values in order to be identified as serial values. So, once the date was entered as text, Excel will give the answer as a decimal fraction. Which means that time is measured as part of the day.
- Since dates are values, they can be subtracted, added or be a part of another computation. The date in serial numbers can be converted to the required format by changing the cell format where the value is entered. With this function, it is necessary to be particular regarding the dates. This is because Excel read dates in a very complicated way. So, once an accurate date is entered in the formula the function will also provide accurate date computation.

return_type – this is the value of the number that distinguishes the kind of return value.

- Once the value of return_type is one or blank, the number returned is 1 through 7, which is Sunday through Saturday.
- Once the return_type value is 2, the number returned is 1 through 7, which is Monday to Sunday.
