Contract

  1. Info.getMinimumDaysInFirstWeek reports locale-specific minimal days thresholds (1 for en-US, 4 for en-GB).
  2. Settings.defaultWeekSettings configures minimalDays and validates that values are between 1 and 7.
  3. minimalDays determines week-year assignment at year boundaries independently of ISO week numbering.
