Clarify time/date filter "between" in reporting

hello there. Not sure if this is a question or suggestion, but I am a bit puzzled by the “between” filter in reporting. I am used to have a distinction between a FROM [date1] to [date2] filter which includes these two dates in the filtering period, and a BETWEEN function which does not.

I’ve tested this and it seems that it does include the dates given: I made a task and filtered on this due day only, and indeed it is taken into account.
