It's no longer a surprise, since it happens every year. Google shows a colorful bar above the search results when you search for [
Christmas], [
Xmas] and other Christmas-related queries. There's also a special bar for
Hanukkah.
You can also check the decorations from
2006,
2007,
2008,
2010, when Google also celebrated
Kwanzaa and
Festivus, the famous Seinfeld holiday.
