NO: Other sequels

Although the 'Die Hard' series consists of five films, only the the first two are set at Christmas.

The third movie, ‘Die Hard with a Vengeance’, sees McClane team up with Zeus Carver (Samuel L. Jackson) at the height of summer to halt a plot to steal the gold in New York.

Considering that three of the five ‘Die Hard’ films are not set anywhere near the holidays, does this mean it shouldn't be considered a Christmas movie?
