Date Operators

An expression that uses a date operator returns a date or a number, depending on the operation. All date operations will result in an accurate date, taking into account the change between years and leap years. The following table shows the date operators:

Operation	Syntax	Returns	Expression	Value
Date difference	Date – Date	Number	!1/20/97! – !1/1/97!	19
Day addition	Date + Number	Date	!1/20/97! + 9	!1/29/97!
Day subtraction	Date – Number	Date	!1/20/97! – 9	!1/11/97!
