Function: applyRecurrenceOverrides()

applyRecurrenceOverrides(newStartAt, originalRecurrence, inputRecurrence?): object

Defined in: src/utilities/recurringEvent/calculation.ts:216

Applies calendar-style override logic for recurring event updates. This function implements the following rules:

1. If startAt is provided and byDay is not specified in recurrence, derive byDay from the new startAt day of week
2. If byDay is explicitly provided in recurrence, use it as-is
3. For monthly/yearly events, similar logic applies to byMonthDay/byMonth

Parameters

newStartAt

The new start time for the event (if provided)

Date | undefined

originalRecurrence

Pick<typeof recurrenceRulesTable.$inferSelect, "frequency" | "interval" | "recurrenceEndDate" | "count" | "byDay" | "byMonth" | "byMonthDay">
