Weekday Formula

How do you tell the day of the week by looking at the date? For example, if you have dates from 07^th Jan 2019 to 13^th Jan 2019 how do you tell what is the day number of the date 10^th Jan 2019 if the start of the week is from Monday. How do you tell weekday number of the date 10^th Jan if the start of the week is from Tuesday?

Yes, we can tell all these by using the built-in function called WEEKDAY in excel. Let’s look at the syntax of the WEEKDAY function.

• Serial Number: This is nothing but the date you are looking to find the weekday number.
• Return Type: This is an optional argument. You need to tell the excel what is the starting day of the week. If you ignore this by default excel takes the argument as Week starting date as Sunday.

We can choose our own start of the weekday by choosing any one of the following return types.

Find Weekend Date by Using Weekday Function

We can find the next weekend date by considering any date in excel. Take a look at the below dates for this example.

Now 10^th May 2018 is on Thursday so the weekend date is on 12^th May 2018 i.e. Saturday. Like this how do you tell the weekend starting date based on the date if the weekday is starting from Monday?

We can tell the next weekend date with the combination of WEEKDAY & IF condition in excel.

Step 1: Open IF condition in the B2 cell.

Step 2: Open WEEKDAY function inside the IF condition and select the date as A2 cell. Week starting date is from Monday i.e. 2 is the criteria.

Step 3: Now test if Weekday function can return 1 as the result.

Step 4: If WEEKDAY result is equal to 1 i.e. Monday, so add five more days to the existing date, it will become Saturday.

Step 5: Now again test if WEEKDAY function can return 2 as the result. If it returns 2 as the result i.e. Tuesday from Tuesday add 4 more days to get the Weekend Date.

Step 6: Like this test all the conditions until WEEKDAY Function returns 5 as the result and add one less day to the existing date to get the weekend date.

Step 7: Now we have set all the weekdays but the date is already a weekend date. So if all these results are FALSE mention the result as “This is the Weekend Date”.

Step 8: Hit enter and we get the result.

Step 9: Drag the formula to other cells to get the results.

Below is the formula I have used to find the next weekend date.

=IF(WEEKDAY(A2,2)=1,A2+5, IF(WEEKDAY(A2,2)=2,A2+4, IF(WEEKDAY(A2,2)=3,A2+3, IF(WEEKDAY(A2,2)=4,A2+2, IF(WEEKDAY(A2,2)=5,A2+1, “This is the Weekend Date”)))))

Excel Formula for Weekday – Example #4

Find Week Day Name by Using Weekday & Choose Function

We have seen WEEKDAY function returns day number in the week. But if we want the name of that day how do you get. We can use CHOOSE + WEEKDAY function to get the weekday name based on the number given by weekday function.

Below is the formula which can give us the desired result.

The Result will be as given below.

Drag the formula to other cells to get the results.

Here WEEKDAY function returns the day number in the week. If weekday returns 1 as the result CHOOSE function chooses Mon as the result because that is the 1^st value we have passed to the argument if weekday returns 2 CHOOSE function chooses Tue as the result i.e. second value in the list. Like this based on the number given by the WEEKDAY function, CHOOSE function returns the result.
