In the United States, Christmas is the last official holiday of the calendar-year, and Thanksgiving is the penultimate holiday. New Year’s Day is the first holiday of the year. Any other holidays among or between these are private rather than public holidays, and thus the public is not obliged to recognize those holidays as if they were equivalent to public holidays. Although New Year’s Day has remained safe from ideological attack, neither Thanksgiving nor Christmas have. Nevertheless, their status as official U.S. holidays has remained, at least as of 2025, and thus it remains as of then at least proper and fitting for Americans to refer to those holidays by name rather than by the denialist, passive-aggressive expression, happy holidays, which conveniently disappears even from retail clerks just in time for New Year’s because that holiday is ideologically permissible. The problem writ large is the influx of ideology trying to invalidate certain official United States holidays. By the end of 2025, the initial influx had triggered a counter-influx that is just as ideological, and thus only encircling certain (but not all) official holidays with ideology.
