The majority of Western nations use a Monday through Friday workday, with Saturday and Sunday being regarded as weekends. The majority of people also view Friday night as being a part of the weekend.
The Jewish Sabbath custom is where the modern concept of the weekend originated. Sunday is a day for worship and rest in various Christian religions. Even though the Christian Sabbath is only observed on Sunday, the Jewish Sabbath, which lasts from Friday evening to Saturday evening, was also included in the traditional period of rest beginning in the 20th century.
In most nations where Muslims make up the bulk of the population, the weekend is either Thursday and Friday or Friday and Saturday.
