:mrdocs:

Return the weekend‐days transition at the specified `index` in this calendar. For all `index` values from 0 to `numWeekendDaysTransitions() ‐ 1` (inclusive), a unique weekend‐days transition is returned. The mapping of `index` to weekend‐days transition is invalidated when the set of weekend‐days transitions is modified by an invocation of `addWeekendDay`, `addWeekendDays`, `addWeekendDaysTransition`, `intersectBusinessDays`, `intersectNonBusinessDays`, `removeAll`, `unionBusinessDays`, or `unionNonBusinessDays`. The behavior is undefined unless `0 <= index < numWeekendDaysTransitions()`.
