With the do not disturb feature, you can obviously select who you want to be able to contact you through do not disturb, or what apps you would still like to receive notifications for.
Therefore, I think that whenever you create a new schedule, you should be able to change the do not disturb settings individually for each one.
For example, during a school day, you probably won't want any notifications at all from people or apps, however, in the evening if you have a schedule for your downtime, you might still want important contacts or apps to still be able to reach you, such as family members or friends in emergencies or other situations!
