Does the "do not disturbe" function turn off by itself each morning - literally ie 1/2 moon disappears?

I have the Schedule turned on (from 10:00PM to 7:00AM). It works fine for one night. The next day I will notice that the Do Not Disturbe feature is now turned off - half moon no longer appears and in settings screen it is set to off.

What I want is for the Do Not Disturb feature to be turned on every night (between 10:00 and 7:00) without me having to turn it on every day.

Can this be done? Or do I have to turn it on (through Settings) every day?
