The calendar editor screen visualizes how the calendar varies over time. You can easily specify the value for a certain time period. The screen also allows you to interactively verify which calendar bucket is effective at a given time.
A calendar has multiple calendar buckets to define the values over time.
The following rules define which entry is valid at a certain time:
- A bucket is only valid from its “start date” (inclusive) till its “end date” (exclusive).Outside of this date range a bucket is never selected.
- If multiple bucket are effective on a date, the one with the lowest “priority” value is taken.In case buckets have the same priority, the value of the bucket with the latest start date is selected.
In case no bucket is effective on a certain date, the calendar will return the “default” value.
