Bonne année is the traditional French greeting for happy new year, used from late December through January to wish friends, family and colleagues well for the year ahead. On TikTok and other short-video platforms, the phrase has become a handy seasonal sound for countdowns, recaps and greeting edits, because it is instantly recognisable even to viewers who do not speak French. Its short length and warm delivery keep it in rotation every festive season, returning each December as creators mark the turn of the year.
