Data validation only dates between

Excel formula: Data validation only dates between
Generic formula 
=AND(A1>=date1),A1<=date2)
Explanation 

Note: Excel has several built-in data validation rules for dates. This page explains how to create a your own validation rule based on a custom formula in case you want or need more control and flexibility.

To allow a user to enter only dates between two dates, you can use data validation with a custom formula based on the AND function.

In the example shown, the data validation applied to C5:C9 is:

=AND(C5>=DATE(2016,6,1),C5<=DATE(2016,6,30))

How this formula works

Data validation rules are triggered when a user adds or changes a cell value.

The AND function takes multiple arguments (logicals) and returns TRUE only when all arguments return TRUE. The DATE function creates a proper Excel date with given year, month, and day values.

Because we want to allow only dates in the month of June 2016, we give AND with two logicals.

The first logical tests that input to C5 is greater than or equal to June 1, 2016:

C5>=DATE(2016,6,1)

The second logical tests that input to C5 is less than or equal to June 30, 2016:

C5<=DATE(2016,6,30)

If both conditions are TRUE, the AND function returns TRUE and input passes validation. If either condition is FALSE, AND returns FALSE and input fails data validation.

Note:  Cell references in data validation formulas are relative to the upper left cell in the range selected when the validation rule is defined, in this case C5.
