Music and dance serve as recreation in many cultures, as do sports and hobbies and sometimes food and drink.
We sometimes use drugs as a form of recreation (see recreational drug use)--and, like dancing, sex, nudism, and other forms of recreation which many people treat as illicit.
The weekend is typically a time for recreation, perhaps (in Judeo-Christian and Muslim cultures) because the Sabbath falls on the weekend and the Sabbath is "the day of rest." Holidays are also a common time for recreation.
