# Excel/Adding days to a date in Excel

Question
Many years ago I used a formula in Excel that someone else has written that had a WEEKEND function in it, now I can only find WORKDAY, so I can't work out how to do it. Anyway is was something like:
(A1) Date + number(A2) = (A3)Date unless A3 = WEEKEND. IF A3 = SATURDAY -1 IF A3 = SUNDAY =1.

I used it in Production scheduling and it was very useful indeed!

On a blank Excel sheet, enter in cell A1

2/4/2013

and in cell B1

5

and in cell A2

=A1+B1+CHOOSE(WEEKDAY(A1+B1),1,0,0,0,0,0,-1)

Cell A2 displays 2/8/2013, because 5 days after 2/4/2013 is Saturday 2/9/2013, and the nearest weekday is Friday 2/8/2013

##### Expertise

I can answer questions relating to MS Excel formulas, or to programming with vba (Visual Basic for Applications) in the Excel environment. Please follow the following guidelines: your question should focus on one specific issue you want to learn. It's beyond the scope of this free service for me to create entire projects or complex vba solutions for you from scratch. You should be able to do most of the work yourself, and come here when you need help with a specific point you're stuck on. ALWAYS include a simple, concrete example illustrating what you want to learn. Explain this example in detail in the text of your question (what data is in which cells of which sheets, etc). Be very precise about the results you want, using this sample to make the logic clear. Always keep these examples SIMPLE. Never e.g. use 18 worksheets in your example if using 2 or 3 will do. Never use ranges like AI567:BB865 if using a range like A1:B3 will do. Thanks.
