If you need to set a quite door bell period this is a cool (high tech) solution. Code and a detailed circuit explanation can be found at Richard Cappels site.
“To set the timer, you just push the button momentarily, and when its released, the amber LED will come on and the doorbell circuit is disabled (the door bell button doesn’t work) for a 10 hour period. At the end of the 10 hour period, the amber LED goes off and the doorbell is enabled. 24 Hours after the button was last pushed, the amber LED comes back on and the door chime circuit is disabled again. this cycle repeats every 24 hours, and because its timing is set by a crystal oscillator, it should be able to go for months or years without needing to be reset.
The toggle switch allows the timer to be bypassed in case we want to have the doorbell operating 24 hours a day or in the unlikely event of a circuit failure. ”
