Our Theatrical Market pages are based on the Domestic Theatrical Market performance only. The Domestic Market is defined as the North American movie territory (consisting of the United States, Canada, Puerto Rico and Guam).
The yearly amounts on our Theatrical Market pages are based on box office years. Each box office year starts on the first Monday of the year, so the previous year ends on the Sunday before the first Monday. For example, the "2017 box office year" started on January 2, 2017 so the "2016 box office year" ended on Sunday, January 1, 2017.
