Schedules are rotations of users who take turns on-call: the user on-call is one that is assigned responsibility when an alert fires.

Each schedule has a few propeties associated with it:

• users: the users on the rotation
• length: number of days each rotation lasts
• start day: the calendar day the rotation starts (example: 2022-05-11)
• start time: the time of day the rotation starts (example: 11:30)

A typical rotation length is between 2 and 7 days. A rotation longer that can result in burnout for the people on that schedule.

Each schedule can also specify overrides that permit allow user to be assigned to applicable alerts. An override contains a start and end date/time and the user taking over during that time period.
