Define a cell value base on the date

[Guest]

I'd like to define the value of a cell to be the first letter of the day of
the week, based on the current year, when I supply the Month and Day from
other cells.

Example:
A1 = "April"
A2 = 1

Since April 1st of this year was a Sunday, the value of my cell, A3, would
be "S"

If I changed A2 to the number 10, then A3 would change to "T" because the
10th of April of this year is a "T"uesday.

I appreciate any help anyone can provide on this.

Just a thought...

What weekday is this: S

Saturday or Sunday?

=IF(OR(A1="",A2=""),"",CHOOSE(WEEKDAY(A1&A2),"Su","M","Tu","W","Th","F","Sa"))
