How does it work?

The method is simple. The WEEKDAY function returns the day number of the given date in its respective week. The CHOOSE function takes this number as an argument and returns the text from the rest of the arguments.

In cell B3, WEEKDAY function returns 4 as Wednesday is the fourth day in a week. Now CHOOSE function takes 4 as an argument and returns the 4th option from the arguments which "We".

In the other method, the SWITCH function takes the argument from WEEKDAY function as 4. Then it looks for 4 in the arguments and returns the corresponding text, which is "We".

So yeah guys, this how you can abbreviate the weekday names to your choice. You can even give them names that no other person can understand, like secret codes (I wonder what will be the need for this).
