Question: what is the formula in excel for date calculations?
Answer: Type a date in Cell A1 and in cell B1, type the formula =EDATE(4/15/2013,-5). Here, we're specifying the value of the start date entering a date enclosed in quotation marks. You can also just refer to a cell that contains a date value or by using the formula =EDATE(A1,-5)for the same result.
