Couple of things, after a brief flight over the code

https://github.com/Bcopeland64/IU-Habit-...ain.py#L70
What is the purpose of main()? You never call it and also it repeats the different cli commands - you can always organise it better, e.g. using dict, instead of this huge if/elif/else


https://github.com/Bcopeland64/IU-Habit-...bit.py#L70
don't change list while iterating over it. Iterate over copy of the list instead:

for i, completed_at in enumerate(self.completed_at[::]):

In all SELECT queries - you will get IndexError if no result is returned (i.e. empty result set), e.g.

 self.cursor.execute(
            'SELECT id FROM habits WHERE name=?',
            (name,)
        )
        habit_id = self.cursor.fetchone()[0]

if name is not present and fetchone() returns empty tuple, there is no index 0
