I would like to create a field that calculates a date that is 39 months from a date I am entering on a form. Once I fill in a date in a field, I would like to have Access calculate the next field which would be 39 months later. What formula would I enter to achieve that effect? Thank you!
Use the dateadd(). In your query design view, click in the box where the field you want to calculate is and type
=DateAdd("m",+39, [the field name for the date entered])
once you click out of the box you will see
Expr1:=DateAdd("m",+39, [the field name for the date entered])
Just change the word "Expr1:" to whatever you want the column name to be and there you go. Be sure there is a colon between your column name and the equal sign that starts the expression ... good luck
