Here's my problem: I'm looking for a formula to change a weekday in the previous month - the day that is 30 days from a day in this month - to a Monday of the following week, if it's a weekday oother than a Monday. For example, if 30 days from the current month (June) is May 24, 2012 (Thursday), I want the formula result to show May 28, 2012 (next Monday). Greatly appreciate any help!
 

Excel Facts

Why are there 1,048,576 rows in Excel?
The Excel team increased the size of the grid in 2007. There are 2^20 rows and 2^14 columns for a total of 17 billion cells.

Maybe this...

A2 = some date

=A2-30+CHOOSE(WEEKDAY(A2-30),1,0,6,5,4,3,2)

Again, thanks! Small request: would you explain the formula, especially the "Choose" part and the numbers that follow? Thanks!

Here ya go...

A2 = some date

=A2-30+CHOOSE(WEEKDAY(A2-30),1,0,6,5,4,3,2)

You want the date for the next Monday if the date minus 30 days is already not a Monday.

We get the date:

A2-30

Then we test what weekday that is:

WEEKDAY(A2-30)

That will return a number from 1 to 7 where:

1 = Sunday
2 = Monday
3= Tuesday
4 = Wednesday
5 = Thursday
6 = Friday
7 = Saturday

We then use that number to CHOOSE how many days we need to add to the date, A2-30, to give us the next Monday date.

Weekday 1 (Sunday) add 1 day
Weekday 2 (Monday) add 0 days
Weekday 3 (Tuesday) add 6 days
Weekday 4 (Wednesday) add 5 days
Weekday 5 (Thursday) add 4 days
Weekday 6 (Friday) add 3 days
Weekday 7 (Saturday) add 2 days
