how to use a date like "TODAY" in a function without listening for the time in that date?

I'm creating a todo list. I know I shouldn't but it I got so stuck on this that I really want to know the answer. At the bottom of my table I have a footer row in which I want to show the total number of tasks to be accomplished today and each time I 'tick' a checkbox in one of the columns used for checking off my todos, I'd like to see it decrease by 1. But apparently from what I found out through experimentation is that the "TODAY" keyword or function word is using the date AND time and only if the time is 00:00:00 AM. So how can I avoid the time to be included when filtering? I'd like to use TODAY because then each day it'll reset itself automatically. Thank you for your time and effort in advance.
