Box office
For movies released in North America, box office figures are usually divided into two categories. The first is domestic. This is the amount a movie earns in the United States and Canada. The second is foreign which includes all other countries. The Weekly box office is the amount a movie makes from Friday through Thursday. The "movie week" starts on Friday because most movies are released on that day.  A large part of this is the weekend box office. It is defined as the amount earned on Friday, Saturday and Sunday. The first weekend after a movie is released is the opening weekend. The amount made by a movie on its opening weekend is what is often reported.
