3756219 - calendardateinterval header shows wrong year after selecting a day in month navigation

Symptom

  • In a fiori application using CalendarDateInterval, when navigating to a specific month (for example, December 2025) and selecting a day (for example, 10), the header incorrectly updates to the next year (for example, December 2026).
  • The behavior is linked to CalendarDateInterval.prototype._setHeaderText calculating an end date and setting the header text incorrectly.
  • The problem persists across multiple UI5 patch versions.
