People have almost no spare time in the community. This is one of the reasons their careers are chosen for them so carefully, in hopes that many of them will enjoy what they do, I suppose. When an unscheduled holiday is called, it is unusual. I also suspect that it is being used to observe people when they are not at work, and record how they choose to spend their spare time. Children do get some free time to play, but once they get a little older they are supposed to spend their time volunteering in various jobs to see which ones they are good at. There is no television, few games or sports, and definitely no books.
In the book The Giver the children relax and learn at the same time. The children have playtime. They play outside and in their homes. The children engage in bicycle races and build with toys. (Page 15)
The adults have very little time for leisure. The entire community seems to evolve around work and function. The family were excited when they were going to get two days off because of the December ceremony. It is only during ceremony times that they are off work. Even the time off is structured by gatherings and ceremonies. In the home they have a leisurely meal and talk about their day. This is their down time. There must be some type of pre-developed recreational activities as Asher is chosen at 12 to become a Recreation Director.
