The time of my pill, how do I change it?

Okay so you’re meat to take you’re pill everyday at around the same time. Basically while I’m at school the is between 7-9. I have an app which I basically like put in that I’ve taken my pill and if I take it after 9 then it has like “inconsistent time”.

Exhibit A^

I am now on my school break and was wondering if I could like make it a later time or like make the “usual” time of taking it slightly later in case I sleep in because I worry. Does this make sense😂
