Names of the days of the week

In many languages, the names given to the seven days of the week are derived from the names of the classical planets in Hellenistic astronomy, which were in turn named after contemporary deities, a system introduced by the Sumerians and later adopted by the Babylonians from whom the Roman Empire adopted the system during late antiquity.^[1] In some other languages, the days are named after corresponding deities of the regional culture, beginning either with Sunday or with Monday. The seven-day week was adopted in early Christianity from the Hebrew calendar, and gradually replaced the Roman internundinum.^{[citation needed]}

Sunday remained the first day of the week, being considered the day of the sun god Sol Invictus and the Lord's Day, while the Jewish Sabbath remained the seventh. The Babylonians invented the actual^{[clarification needed]} seven-day week in 600 BCE, with Emperor Constantine making the Day of the Sun (dies Solis, "Sunday") a legal holiday centuries later.^[2]

In the international standard ISO 8601, Monday is treated as the first day of the week, but in many countries it is counted as the second day of the week.

Between the first and third centuries CE, the Roman Empire gradually replaced the eight-day Roman nundinal cycle with the seven-day week. The earliest evidence for this new system is a Pompeiian graffito referring to 6 February (ante diem viii idus Februarias) of the year 60 CE as dies solis ("Sunday").^[3] Another early witness is a reference to a lost treatise by Plutarch, written in about 100 CE, which addressed the question of: "Why are the days named after the planets reckoned in a different order from the 'actual' order?"^[4] The treatise is lost, but the answer to the question is known; see planetary hours.^{[citation needed]}

The Ptolemaic system of planetary spheres asserts that the order of the heavenly bodies from the farthest to the closest to the Earth is Saturn, Jupiter, Mars, Sun, Venus, Mercury, and the Moon; objectively, the planets are ordered from slowest to fastest moving as they appear in the night sky.^[5]

The days were named after the classical planets of Hellenistic astrology, in the order: Sun (Helios), Moon (Selene), Mars (Ares), Mercury (Hermes), Jupiter (Zeus), Venus (Aphrodite), and Saturn (Cronus).^[6]

The seven-day week spread throughout the Roman Empire in late antiquity. By the fourth century CE, it was in wide use throughout the Empire. ^{[citation needed]}

The Greek and Latin names are as follows:

Day: (see Irregularities)	Sunday Sōl or Helios (Sun)	Monday Luna or Selene (Moon)	Tuesday Mars or Ares (Mars)	Wednesday Mercurius or Hermes (Mercury)	Thursday Jove or Zeus (Jupiter)	Friday Venus or Aphrodite (Venus)	Saturday Saturnus or Cronus (Saturn)

Except for in Portuguese and Mirandese, the Romance languages preserved the Latin names, except for the names of Sunday, which was replaced by [dies] Dominicus (Dominica), that is, "the Lord's Day", and of Saturday, which was named for the Jewish Sabbath. Mirandese and Portuguese use numbered weekdays, but retain sábado and demingo/domingo for weekends.^[8] Meanwhile, Galician occasionally uses them alongside the traditional Latin-derived names, albeit to a lesser extent (see below).

Early Old Irish adopted the names from Latin, but introduced separate terms of Norse origin for Wednesday, Thursday and Friday, then later supplanted these with terms relating to church fasting practices.

Albanian adopted the Latin terms for Tuesday, Wednesday and Saturday, translated the Latin terms for Sunday and Monday using the native names of Diell and Hënë, respectively, and replaced the Latin terms for Thursday and Friday with the equivalent native deity names Enji and Prende, respectively.^[18]

Other languages adopted the week together with the Latin (Romance) names for the days of the week in the colonial period. Several constructed languages also adopted the Latin terminology.

The Germanic peoples adapted the system introduced by the Romans by substituting the Germanic deities for the Roman ones (with the exception of Saturday) in a process known as interpretatio germanica. The date of the introduction of this system is not known exactly, but it must have happened later than 100 AD but before the introduction of Christianity during the 6th to 7th centuries, i.e., during the final phase or soon after the collapse of the Western Roman Empire.^[20] This period is later than the Common Germanic stage, but still during the phase of undifferentiated West Germanic. The names of the days of the week in North Germanic languages were not calqued from Latin directly, but taken from the West Germanic names.

• Sunday: Old English Sunnandæg (pronounced [ˈsunnɑndæj]), meaning "sun's day". This is a translation of the Latin phrase diēs Sōlis. English, like most of the Germanic languages, preserves the day's association with the sun. Many other European languages, including all of the Romance languages, have changed its name to the equivalent of "the Lord's day" (based on Ecclesiastical Latin dies Dominica). In both West Germanic and North Germanic mythology, the Sun is personified as Sunna/Sól.
• Monday: Old English Mōnandæg (pronounced [ˈmoːnɑndæj]), meaning "Moon's day". This is equivalent to the Latin name diēs Lūnae. In North Germanic mythology, the Moon is personified as Máni.
• Tuesday: Old English Tīwesdæg (pronounced [ˈtiːwezdæj]), meaning "Tiw's day". Tiw (Norse Týr) was a one-handed god associated with single combat and pledges in Norse mythology and also attested prominently in wider Germanic paganism. The name of the day is also related to the Latin name diēs Mārtis, "Day of Mars" (the Roman god of war).
• Wednesday: Old English Wōdnesdæg (pronounced [ˈwoːdnezdæj]) meaning the day of the Germanic god Woden (known as Óðinn among the North Germanic peoples), and a prominent god of the Anglo-Saxons (and other Germanic peoples) in England until about the seventh century. This corresponds to the Latin counterpart diēs Mercuriī, "Day of Mercury", as both are deities of magic and knowledge. The German Mittwoch, the Low German Middeweek, the miðviku- in Icelandic miðvikudagur and the Finnish keskiviikko all mean "mid-week".
• Thursday: Old English Þūnresdæg (pronounced [ˈθuːnrezdæj]), meaning 'Þunor's day'. Þunor means thunder or its personification, the Norse god known in Modern English as Thor. Similarly Dutch donderdag, German Donnerstag ('thunder's day'), Finnish torstai, and Scandinavian torsdag ('Thor's day'). "Thor's day" corresponds to Latin diēs Iovis, "day of Jupiter" (the Roman god of thunder).
• Friday: Old English Frīgedæg (pronounced [ˈfriːjedæj]), meaning the day of the Anglo-Saxon goddess Frīg. The Norse name for the planet Venus was Friggjarstjarna, 'Frigg's star'.^[21] It is based on the Latin diēs Veneris, "Day of Venus".
• Saturday: named after the Roman god Saturn associated with the Titan Cronus, father of Zeus and many Olympians. Its original Anglo-Saxon rendering was Sæturnesdæg (pronounced [ˈsæturnezdæj]). In Latin, it was diēs Sāturnī, "Day of Saturn". The Nordic laugardagur, leygardagur, laurdag, etc. deviate significantly as they have no reference to either the Norse or the Roman pantheon; they derive from Old Nordic laugardagr, literally "washing-day". The German Sonnabend (mainly used in northern and eastern Germany) and the Low German Sünnavend mean "Sunday Eve"; the German word Samstag derives from the name for Shabbat.

Hindu astrology uses the concept of days under the regency of a planet^{[clarification needed]} under the term vāsara/vāra, the days of the week being called sūrya-/ravi-, chandra-/soma-, maṅgala-, budha-, guru-/bṛhaspati-, śukra-, and śani-vāsara. śukrá is a name of Venus (regarded as a son of Bhṛgu); guru is here a title of Bṛhaspati, and hence of Jupiter; budha "Mercury" is regarded as a son of Soma, that is, the Moon.^[22] Knowledge of Greek astrology existed since about the 2nd century BC^{[citation needed]}, but references to the vāsara occur somewhat later, during the Gupta period (Yājñavalkya Smṛti, c. 3rd to 5th century AD), that is, at roughly the same period or before the system was introduced in the Roman Empire.^{[citation needed]}

The Southeast Asian tradition also uses the Hindu names of the days of the week. Hindu astrology adopted the concept of days under the regency of a planet under the term vāra, the days of the week being called āditya-, soma-, maṅgala-, budha-, guru-, śukra-, and śani-vāra. śukrá is a name of Venus (regarded as a son of Bhṛgu); guru is here a title of Bṛhaspati, and hence of Jupiter; budha "Mercury" is regarded as a son of Soma, that is, the Moon.^[23]

The East Asian naming system for the days of the week closely parallels that of the Latin system and is ordered after the "Seven Luminaries" (七曜 qī yào), which consists of the Sun, Moon and the five planets visible to the naked eye.

The Chinese had apparently adopted the seven-day week from the Hellenistic system by the 4th century AD, although by which route is not entirely clear. It was again transmitted to China in the 8th century AD by Manichaeans, via the country of Kang (a Central Asian polity near Samarkand).^[24] The 4th-century AD date, according to the Cihai encyclopedia,^{[year needed]} is due to a reference to Fan Ning (范寧), an astrologer of the Jin dynasty. The renewed adoption from Manichaeans in the 8th century AD (Tang dynasty) is documented with the writings of the Chinese Buddhist monk Yijing and the Ceylonese Buddhist monk Bu Kong.

The Chinese transliteration of the planetary system was soon brought to Japan by the Japanese monk Kobo Daishi; surviving diaries of the Japanese statesman Fujiwara no Michinaga show the seven-day system in use in Heian Period Japan as early as 1007. In Japan, the seven-day system was kept in use (for astrological purposes) until its promotion to a full-fledged (Western-style) calendrical basis during the Meiji era. In China, with the founding of the Republic of China in 1911, Monday through Saturday in China are now named after the luminaries implicitly with the numbers.

Pronunciations for Classical Chinese names are given in Standard Chinese.

ISO prescribes Monday as the first day of the week with ISO-8601 for software date formats.

The Slavic, Baltic and Uralic languages (except Finnish and partially Estonian and Võro) adopted numbering but took Monday rather than Sunday as the "first day".^[25] This convention is also found in some Austronesian languages whose speakers were converted to Christianity by European missionaries.^[26]

In Slavic languages, some of the names correspond to numerals after Sunday: compare Russian vtornik (вторник) "Tuesday" and vtoroj (второй) "the second", chetverg (четверг) "Thursday" and chetvjortyj (четвёртый) "the fourth", pyatnitsa (пятница) "Friday" and pyatyj (пятый) "the fifth"; see also the Notes.

In Standard Chinese, the week is referred to as the "Stellar Period" (Chinese: 星期; pinyin: Xīngqī) or "Cycle" (simplified Chinese: 周; traditional Chinese: 週; pinyin: Zhōu).

The modern Chinese names for the days of the week are based on a simple numerical sequence. The word for "week" is followed by a number indicating the day: "Monday" is literally the "Stellar Period One"/"Cycle One", that is, the "First day of the Stellar Period/Cycle", etc. The exception is Sunday, where 日 (rì), "day" or "Sun", is used instead of a number.^[28] A slightly informal and colloquial variant to 日 is 天 (tiān) "day", "sky" or "heaven". However, the term 週天 is rarely used compared to 星期天.

Accordingly, the notational abbreviation of the days of the week uses the numbers, for example, 一 for "M" or "Mon(.)", "Monday". The abbreviation of Sunday uses exclusively 日 and not 天. Attempted usage of 天 as such will not be understood.

Colloquially, the week is also known as the "Worship" (simplified Chinese: 礼拜; traditional Chinese: 禮拜; pinyin: Lǐbài), with the names of the days of the week formed accordingly. This is also dominant in certain regional varieties of Chinese.

The following is a table of the Mandarin names of the days of the weeks. Note that standard Taiwan Mandarin pronounces 期 as qí, so 星期 is instead xīngqí. While all varieties of Mandarin may pronounce 星期 as xīngqi and 禮拜/礼拜 as lǐbai, the second syllable with the neutral tone, this is not reflected in the table either for legibility.

Day	Monday	Tuesday	Wednesday	Thursday	Friday	Saturday	Sunday
Standard Modern Chinese	星期一 Xīngqīyī	星期二 Xīngqī'èr	星期三 Xīngqīsān	星期四 Xīngqīsì	星期五 Xīngqīwǔ	星期六 Xīngqīliù	星期日/星期天 Xīngqīrì (or Xīngqītiān)
	週一 Zhōuyī	週二 Zhōu'èr	週三 Zhōusān	週四 Zhōusì	週五 Zhōuwǔ	週六 Zhōuliù	週日/週天 Zhōurì (or Zhōutiān, rarely used)
Standard Modern Chinese (regional, informal, colloquial)	禮拜一 Lǐbàiyī	禮拜二 Lǐbài'èr	禮拜三 Lǐbàisān	禮拜四 Lǐbàisì	禮拜五 Lǐbàiwǔ	禮拜六 Lǐbàiliù	禮拜天/禮拜日 Lǐbàitiān (or Lǐbàirì)

Several Sinitic languages refer to Saturday as 週末 "end of the week" and Sunday as 禮拜. Examples include Shenyang Mandarin, Hanyuan Sichuanese Mandarin, Taishanese, Yudu Hakka, Teochew, Ningbonese, and Loudi Old Xiang. Some Hakka varieties in Taiwan still use the traditional Luminaries.

Sunday comes first in order in calendars shown in the table below. In the Abrahamic tradition, the first day of the week is Sunday. Biblical Sabbath (corresponding to Saturday) is when God rested from six-day Creation, making the day following the Sabbath the first day of the week (corresponding to Sunday). Seventh-day Sabbaths were sanctified for celebration and rest. After the week was adopted in early Christianity, Sunday remained the first day of the week, but also gradually displaced Saturday as the day of celebration and rest, being considered the Lord's Day.

Saint Martin of Dumio (c. 520–580), archbishop of Braga, decided not to call days by pagan gods and to use ecclesiastic terminology to designate them. While the custom of numbering the days of the week was mostly prevalent in the Eastern Church, Portuguese and Mirandese, due to Martin's influence, are the only Romance languages in which the names of the days come from numbers rather than planetary names.

Members of the Religious Society of Friends (Quakers) historically objected to the pagan etymologies of days and months and substituted numbering, beginning with First Day for Sunday.

Icelandic is a special case within the Germanic languages, maintaining only the Sun and Moon (sunnudagur and mánudagur respectively), while dispensing with the names of the explicitly heathen gods in favour of a combination of numbered days and days whose names are linked to pious or domestic routine (föstudagur, "Fasting Day" and laugardagur, "Washing Day"). The "washing day" is also used in other North Germanic languages, but otherwise the names correspond to those of English.

In Swahili, the day begins at sunrise, unlike in the Arabic and Hebrew calendars where the day starts at sunset (therefore an offset of twelve hours on average), and unlike in the Western world where the day starts at midnight (therefore an offset of six hours on average). Saturday is therefore the first day of the week, as it is the day that includes the first night of the week in Arabic.

Etymologically speaking, Swahili has two "fifth" days. The words for Saturday through Wednesday contain the Bantu-derived Swahili words for "one" through "five". The word for Thursday, Alhamisi, is of Arabic origin and means "the fifth" (day). The word for Friday, Ijumaa, is also Arabic and means (day of) "gathering" for the Friday noon prayers in Islam.

There are several systems in the different Basque dialects.^[31]

Day	Monday	Tuesday	Wednesday	Thursday	Friday	Saturday	Sunday
Standard Basque, Guipuscoan Basque	astelehena ("week-first")	asteartea ("week-between")	asteazkena ("week-last")	osteguna ("Ortzi/Sky day")	ostirala (see Ortzi)	larunbata ("fourth", "meeting of friends"), neskenegun ("girls' day")	igandea
Biscayne Basque	astelena ("week-first"), ilen ("Moon day")	martitzena ("Mars day")	eguaztena ("day last")	eguena ("day of days", "day of light")	barikua ("day without supper"), egubakotx	zapatua (compare with Spanish sábado from Sabbath)	domeka (from Latin Dominica [dies])

In Judaeo-Spanish (Ladino), which is mainly based on a medieval version of Spanish, the five days of Monday–Friday closely follow the Spanish names. For Sunday is used the Arabic name, which is based on numbering (meaning "Day one" or "First day"), because a Jewish language was not likely to adapt a name based on "Lord's Day" for Sunday. As in Spanish, the Ladino name for Saturday is based on Sabbath. However, as a Jewish language—and with Saturday being the actual day of rest in the Jewish community—Ladino directly adapted the Hebrew name, Shabbat.^[32]
