Count Between Dates By Date Range

COUNTIFS(Range,">="&Start Date,Range,"<="&End Date) 

The COUNTIFS formula you provided is used to count the number of cells in a given range that meet two criteria. The formula includes three arguments:

1. Range - This is the range of cells that you want to evaluate for the given criteria.
2. ">="&Start Date - This criterion filters the "Range" based on a minimum date that is greater than or equal to the "Start Date" value. The ">=" symbol is used to represent "greater than or equal to", and is concatenated with the "Start Date" value using the "&" symbol. The "&" symbol is used to combine or concatenate the text string ">=" with the actual "Start Date" value.
3. "<="&End Date - This criterion filters the "Range" based on a maximum date that is less than or equal to the "End Date" value. The "<=" symbol is used to represent "less than or equal to", and is concatenated with the "End Date" value using the "&" symbol. The "&" symbol is used to combine or concatenate the text string "<=" with the actual "End Date" value.

The formula counts the number of cells in the given range that meet both criteria, which is to have a date that is greater than or equal to the "Start Date" and less than or equal to the "End Date".

For example, if you have a range of dates and you want to count the number of dates that fall between a specific range of dates, you can use this formula. The dates in the "Range" argument should be formatted as dates, and the "Start Date" and "End Date" should be entered as date values or referenced from cells that contain date values.
