public class BoxingDayCAD
extends Object
implements Observance

Observance of Boxing Day for the Bank of Canada (Lynx) settlement calendar.

Boxing Day (26 December) must be computed in tandem with Christmas Day (25 December) because the two holidays can collide when Christmas falls on a weekend. The framework's DateRoll mechanism operates independently per holiday and cannot detect when Christmas Day has already consumed 26 December as its observed Monday substitute. This observance therefore encapsulates the full substitution logic for the Christmas/Boxing Day pair:

• Dec 25 = Saturday → Christmas observed Mon 27; Boxing Day (Dec 26 = Sunday) observed Tue 28.
• Dec 25 = Sunday → Christmas observed Mon 26; Boxing Day displaced to Tue 27.
• Dec 26 = Saturday (Christmas is Friday) → Christmas not rolled; Boxing Day observed Mon 28.
• Dec 26 = Sunday (Christmas is Saturday — covered by first case above; or Christmas is a different weekday) → Boxing Day observed Mon 27.
• All other cases → Boxing Day observed on its natural date, 26 December.
