How many parts were in Advent calendars of yore? Is there any convenient way to find out how many pieces were in previous years' Advent calendars?  I looked through a dozen calendars on bricklink and most of them do not include the part count in the picture.  I was only able to find:


2010 City - 271 pieces


I started looking for this because the 2015 Advent Calendars range from 233-292 pieces so I wanted to know what was typical for prior years.
