In the majority of Western nations, the workweek runs from Monday to Friday, with Saturday and Sunday being the weekend. The majority of individuals also consider Friday night to be part of the weekend.
The contemporary concept of the weekend originated with the Jewish Sabbath. Sunday is reserved by various Christian groups for worship and repose. Although the Christian Sabbath is only one day, beginning in the 20th century, Sunday, the customary day of rest, also embraced the Jewish Sabbath, which is from Friday evening to Saturday evening. In the majority of Muslim-dominated countries, the weekend is either Thursday and Friday or Friday and Saturday.
