Considerations when using the DATESBETWEEN function
If start_date is a blank date value, then start_date will be the earliest value in the dates column.
If end_date is a blank date value, then end_date will be the latest value in the dates column.
The dates used as the start_date and end_date are inclusive: that is, if the sales occurred on September 1 and you use September 1 as the start date, sales on September 1 are counted.
If you are working with common date intervals such as months, quarters, and years, we recommend that you use the appropriate function, such as DATESINPERIOD.
