Many public and private employers, as well as school systems, provide additional days off around the end of December, often including at least a full or half-day on December 24 (Christmas Eve) or December 31 (New Year's Eve), or in some cases the entire week between Christmas and New Year. While not officially legislated in any capacity, internationally notable cultural holidays such as Valentine's Day, St. Patrick's Day, Halloween, Mother's Day, and Father's Day are traditionally observed by Canadians as part of Canadian culture.
