Thank Goodness It's Friday

Friday is the day after Thursday and the day before Saturday. In countries adopting Monday-first conventions as recommended by the international standard ISO 8601, it is the fifth day of the week. In countries that adopt a Sunday-first convention, it is the sixth day of the week. In other countries (see workweek and weekend), Friday is the first day of the week-end, with Saturday the second. In Afghanistan and Iran, Friday is the last day of the week-end, with Saturday as the first day of the working week. Bahrain, the United Arab Emirates (U.A.E.) and Kuwait also followed this convention until they changed to a Friday–Saturday week-end, on September first, 2006 in Bahrain and the U.A.E., and a year later in Kuwait. In Iran, Friday is the only week-end day. In Saudi Arabia and the Maldives, there are two week-ends where Friday is the first week-end of the week while Saturday is the second week-end.

The name Friday comes from the Old English Frīġedæġ, meaning the "day of Frige", a result of an old convention associating the Old English goddess Frigg with the Roman goddess Venus, with whom the day is associated in many different cultures. The same holds for Frīatag in Old High German, Freitag in Modern German, and vrijdag in Dutch.
