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.
The expected cognate name in Old Norse would be *friggjar-dagr. However, the name of Friday in Old Norse is frjá-dagr instead, indicating a loan of the week-day names from Low German. The modern Scandinavian form is Fredag in Swedish, Norwegian, and Danish, meaning Freyja's day. The distinction between Freyja and Frigg in some Germanic mythologies is contested.
The word for Friday in most Romance languages is derived from Latin dies Veneris or "day of Venus" (a translation of Greek Aphrodites hemera), such as vendredi in French, divendres in Catalan, vennari in Corsican, venerdì in Italian, vineri in Romanian, and viernes in Spanish and influencing the Filipino biyernes or byernes. This is also reflected in the p-Celtic Welsh language as Gwener .
An exception is Portuguese, also a Romance language, which uses the word sexta-feira, meaning "sixth day of liturgical celebration", derived from the Latin "feria sexta" used in religious texts where it was not allowed to consecrate days to pagan gods. The Sardinian word chenàpura also figures as an exception among all the other Romance languages, since it is derived from Latin cena pura. This name had been given by the Jewish community exiled to the island in order to designate the food specifically prepared for Shabbat eve.
In Arabic, Friday is الجمعة al-jum`ah, from a root meaning "congregation/gathering." In languages of Islamic countries outside the Arab world, the word for Friday is commonly a derivation of this: (Indonesian jumat, Malay jumaat, Turkish cuma, Persian "جمعه").
In modern Greek, four of the words for the week-days are derived from ordinals. However, the Greek word for Friday is Paraskevi (Παρασκευή) and is derived from a word meaning "to prepare" (παρασκευάζω). Like Saturday (Savvato, Σάββατο) and Sunday (Kyriaki, Κυριακή), Friday is named for its liturgical significance as the day of preparation before Sabbath, which was inherited by Greek Christian Orthodox culture from Jewish practices.
In both biblical and modern Hebrew, Friday is Yom Shishi meaning "the sixth day."
Most Slavic languages call Friday the "fifth (day)": Belarusian пятніца – pyatnitsa, Bulgarian петък – petŭk, Croatian petak, Czech pátek, Polish piątek, Russian пятница – pyatnitsa, Serbian петак – petak, Slovak piatok, Slovene petek, and Ukrainian п'ятниця – p'yatnitsya. The Hungarian word péntek is a loan from Pannonian dialect of Slavic language. The n in péntek suggests an early adoption from Slavic, when many Slavic dialects still had nasal vowels. In modern Slavic languages only Polish retained nasal vowels.
Friday is considered unlucky in some cultures. This is particularly so in maritime circles; perhaps the most enduring sailing superstition is that it is unlucky to begin a voyage on a Friday. In the 19th century, Admiral William Henry Smyth described Friday in his nautical lexicon The Sailor's Word-Book as:
The Dies Infaustus, on which old seamen were desirous of not getting under weigh, as ill-omened.
However, this superstition is not universal, notably in Scottish Gaelic culture:
Though Friday has always been held an unlucky day in many Christian countries, still in the Hebrides it is supposed that it is a lucky day for sowing the seed. Good Friday in particular is a favourite day for potato planting—even strict Roman Catholics make a point of planting a bucketful on that day. Probably the idea is that as the Resurrection followed the Crucifixion, and Burial so too in the case of the seed, and after death will come life?
Traditionally, Roman Catholics were obliged to refrain from eating the meat of land animals on Fridays, although fish was allowed. However, Episcopal conferences are now authorized to allow some other form of penance to replace abstinence from meat. Nonetheless, many Christians still choose the traditional form of Friday penance.
The 1983 Code of Canon Law states:
- Canon 1250. The days and times of penance for the universal Church are each Friday of the whole year and the season of Lent.
- Canon 1251. Abstinence from meat, or from some other food as determined by the Episcopal Conference, is to be observed on all Fridays, unless a solemnity should fall on a Friday. Abstinence and fasting are to be observed on Ash Wednesday and Good Friday.
- Canon 1253. The Episcopal Conference can determine more particular ways in which fasting and abstinence are to be observed. In place of abstinence or fasting it can substitute, in whole or in part, other forms of penance, especially works of charity and exercises of piety.
Some Anglicans (particularly Anglo-Catholics) also practice abstinence from meat either on all Fridays or on Fridays in Lent. More generally, traditional Anglican Prayer Books prescribe weekly Friday abstinence for all Anglicans.
The Eastern Orthodox Church continues to observe Fridays (as well as Wednesdays) as fast days throughout the year (with the exception of several fast-free periods during the year). Fasting on Fridays entails abstinence from meat or meat products (i.e., quadrupeds), poultry, and dairy products (as well as fish). Unless a feast day occurs on a Friday, the Orthodox also abstain from using oil in their cooking and from alcoholic beverages (there is some debate over whether abstention from oil involves all cooking oil or only olive oil). On particularly important feast days, fish may also be permitted. For the Orthodox, Fridays throughout the year commemorate the Crucifixion of Christ and the Theotokos (Mother of God), especially as she stood by the foot of the cross. There are hymns in the Octoekhos which reflect this liturgically. These include Theotokia (hymns to the Mother of God) which are chanted on Wednesdays and Fridays called Stavrotheotokia ("Cross-Theotokia"). The dismissal at the end of services on Fridays begins with the words: "May Christ our true God, through the power of the precious and life-giving cross...."
In Islam, Friday (from sun-down Thursday to sun-down Friday, simpler than midnight to midnight in a pre-clock age) corresponds as a holy day to Sunday in Christianity and Saturday (Friday evening to Saturday evening) in Judaism and Sabbatarian Christianity. Friday observance includes attendance at a mosque for congregation prayer or Salat AlJumu'ah. It is considered a day of peace and mercy (see Jumu'ah) as well as a day of rest.
According to some Islamic traditions, the day is stated to be the original holy day ordained by Allah, but that now Jews and Christians recognize the days after. In some Islamic countries, the week begins on Sunday and ends on Saturday, just like the Jewish week and the week in some Christian countries. The week begins on Saturday and ends on Friday in most other Islamic countries, such as Saudi Arabia, Somalia, and Iran. Friday is also the day of rest in the Bahá'í Faith. In some Malaysian states, Friday is made as the first week-end, with Saturday as the second week-end to allow Muslims to perform their religious obligations on Friday in a more peaceful manner. Sunday is the first working day of the week for governmental organisations.
