Scheduling Do Not Disturb helps turn off all notifications at specific times so no one interrupts you each day around that time.
Go to Settings
Go to Notifications
Inside Notifications, go to Do Not Disturb
Turn on Scheduled then set the timer
Depending on what time you set it at, everyday between those times, it will turn on Do Not Disturb
You can also make it allow specific calls to be allowed, and have it ring after someone calls again 3 minutes after calling when Do Not Disturb is on
