When calculating with dates in Access, you can hard-code an arbitrary date by using the following syntax:ДЇor example, you would use the following code to subtract a date from Jan. Instead, consider using more descriptive names, such as BeginDate, HireDate, etc. Cognito also supports an error indicator to help you know when a calculation is not working and exactly where. When naming date fields in Access, avoid naming a field Date, since this is a built-in Access function. (In the example above, Date1 would be subtracted from Date2.) The other intervals that can be used in this expression are as follows: вЂњyyyyвЂќ вЂ“ Years, вЂњmвЂќ вЂ“ Months, вЂњyвЂќ вЂ“ Day of Year, вЂњdвЂќ вЂ“ Day, вЂњwвЂќ вЂ“ Weekdays, вЂњwwвЂќ вЂ“ Weeks, вЂњhвЂќ вЂ“ Hours, вЂњnвЂќ вЂ“ Minutes, вЂњsвЂќ вЂ“ Seconds.

Access adds a text box to the Report Footer section and sets its Control Source property to an expression that performs the calculation you want.
