The Boo Year's Eve Countdown Calendar is a feature on the Monster High website that ran from December 13, 2012 to January 1, 2013. It is a calendar containing twenty sheets, each reserved for one of the Monster High students and their resolutions for 2013. However, since there are more than twenty students, not all of them are featured in the calendar. A number of wishes were mentioned in the webisode "Boo Year's Eve", which was announced at the same time as the Boo Year's Eve Countdown Calendar was launched and aired at the same time as the calendar ended.
