Dates can be tricky with Excel VBA AutoFilter. Some find it easier to just loop through the array to be filtered.
Sometimes I have found that one can use the numeric value of the date, especially when dealing with “dates between”
Criteria1:= ">" & CDbl([datecell])
Criteria2:= "<=" & CDbl(WorksheetFunction.EoMonth([datecell], 3))
Note that the above need to be “real dates” and not strings that look like dates. Even a single “string date” will mess things up.
