How do I prevent phone from ringing certain times of the day?

I am familiar with the "Do Not Disturb" feature, however, it is inadequate in that I need to make my phone not ring both at night and while I am at work.

The "Do Not Disturb" feature only allows one start time and one end time where I want my phone to not ring or beep from 10 pm to 6 am every day, and then 8:30 am to lunch, and then 1 to 3:30 pm Monday to Friday.

I find friends generally know that you are at work and that it is inappropriate to be calling during working hours, but give a business your number, and they have no common sense or discretion that most people carry their mobile phones, they work, and phones ringing at work for personal issues is a problem.

There are many apps that can change ringing settings based on a schedule. If all you want is it silent at certain times each week even something as simple as Timeriffic can do that.
