Is there any function/formula that can count how many times a particular cell, which has a date in it, changes? Thanks!!!

You'd want a VBA Worksheet Change event, if the date is not there by Worksheet Function. See the following:

However, if it's there by function, e.g., Today(), which is volatile, you might want to consider the Calculate event.
