If you live in a town or city, you have a lot more options for day of rests.
The days themselves are just one aspect of the calendar, and there are plenty of others. The months of the calendar represent various seasons, and the time between each of those months gives us the seasonal cycle. At the start of spring, the temperature is high and the days are warm, while at the end of winter season the air is cold and the days are chilly. Every season has its own unique time associated with it, and the calendar assists us monitor all of those shifts. Any seasonal modification is reflected in the calendar, and it informs us when and where to go during certain times of the year.
