Monday, October 13, served as a primary anchor for regional long weekends. In Canada, Thanksgiving Day brought federal and provincial closures, encouraging family gatherings and seasonal travel. Concurrently, the United States observed Columbus Day and Indigenous Peoples' Day, affecting federal institutions, postal services, and state-level government offices.

Global Public Holidays

International schedules featured prominent national celebrations. China observed its National Day Golden Week starting Wednesday, October 1, leading to widespread travel surges domestically and across East Asia. Germany marked the Day of German Unity on Friday, October 3, creating a seamless three-day weekend for workers nationwide.
