This is my Custom Function and I want to edit it

Discuss:

Let ( cd = Get ( CurrentDate ) ;
Month ( cd - date( cd ) )
)

Using Let() save change of current data in calculating.

Hello unix,
I presume "date( cd )" must be "month( cd )" ?
Best regards.

I edited the function to take a date in parameter. If you give and empty string it will work like the last version.

Thanks Bernamo,
It should be Day( cd ).
(And "current data" should be "current date", of course)

aDate - Day ( aDate )
returns the last date of previous month.

I frequently confuse date and day...
