Noun
Christmas creep (uncountable)
The inexorable tendency for the commercial aspects of Christmas to appear earlier every year.
Cultural influences such as Christmas creep may have led to the winter season being perceived as beginning earlier in recent years, although high latitude countries like Canada are usually well into their real winters before the December solstice. Source: Internet
