"Greatest Time of Year" is a song from Aly & AJ's Christmas album Acoustic Hearts of Winter.

The song was used as the finale for the 2009 Disney on Ice show, "Let's Celebrate".

[1] The video does not include the intro but instead skips to the first verse of the song, and it also leaves out a small 8 second snippet just before the bridge.

The music video first aired on Disney Channel after Twitches in October 2006.

Disney has begun airing it more frequently once The Santa Clause 3 came out in theaters and its Billboard debut.
