This is my Custom Function and I want to edit it

Discuss:

Great function. I would like to count the current day and am having some trouble figuring how to include it.

If it is Monday, and the offset is 5, I would like the date to show the following Friday rather than the following Monday.

Any suggestions on how the modification would look?

Have you considered just subtracting a day from your offset? :-)

Otherwise if you are always counting the current day in your offset, just add or subtract a 1 where appropriate:

If (

// Offset is a negative value
offset < 0 ; startDate + Int ( (offset + 1) / 5 ) * 7 - Middle( "23456034560145601256012360123412345" ; ( DayOfWeek ( startDate ) - 1 ) * 5 + Mod ( Abs ( (offset + 1) ) ; 5 ) + 1 ; 1 ) ;

// Offset is a positive value
startDate + Int ( (offset - 1) / 5 ) * 7 + Middle ( "12345012340123601256014560345623456" ; ( DayOfWeek ( startDate ) - 1 ) * 5 + Mod ( (offset - 1) ; 5 ) + 1 ; 1 )

)
