Ability to disable alerts for provided time range

It doesn't seem like a way to disable alerts for a given time range. Time range could be every day from X to Y hours or could be a specific day in the month, etc.

The issue does not identify files, tests, or an entry point. Start by locating the alert scheduling and configuration code, then define how recurring daily windows and specific days of the month should be represented. Done means alerts can be disabled for both requested kinds of time range.
