( December 2013 ) Italian cameo bracelet representing the days of the week, corresponding to the planets as Roman gods : Diana as the Moon for Monday, Mars for Tuesday, Mercury for Wednesday, Jupiter for Thursday, Venus for Friday, Saturn for Saturday, and Apollo as the Sun for Sunday. Middle 19th century, Walters Art Museum The names of the days of the week in many languages are derived from the names of the classical planets in Hellenistic astrology, which were in turn named after contemporary deities, a system introduced in by the Roman Empire during Late Antiquity. In some other languages, the days are named after corresponding deities of the regional culture, either beginning with Sunday or with Monday. In the international standard ISO 8601, Monday is treated as the first day of the week.

Our earliest evidence for this new system is a Pompeiian graffito referring to the 6th February ( viii idus Februarius ) of the year AD 60 as dies solis ( `` Sunday '' ). Another early witness is a reference to a lost treatise by Plutarch, written in about AD 100, which addressed the question of Why are the days named after the planets reckoned in a different order from the actual order ?. The days were named after the planets of Hellenistic astrology, in the order Sun, Moon, Mars ( Ares ), Mercury ( Hermes ), Jupiter ( Zeus ), Venus ( Aphrodite ) and Saturn ( Cronos ). The seven - day week spread throughout the Roman Empire in Late Antiquity. By the 4th century, it was in wide use throughout the Empire, and it had also reached India and China.

The date of the introduction of this system is not known exactly, but it must have happened later than AD 200 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. 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 dies Solis. English, like most of the Germanic languages, preserves the original pagan / sun associations of the day. 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 dies lunae. 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 dies Martis, `` Day of Mars ''. 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. It is also vaguely related to the Latin counterpart dies Mercurii, `` Day of Mercury ''. The connection between Mercury and Odin is more strained than the other syncretic connections. The usual explanation is that both Wodan and Mercury were considered psychopomps, or guides of souls after death, in their respective mythologies ; both are also associated with poetic and musical inspiration. The Icelandic Miðviku, German Mittwoch, Low German Middeweek and 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 dies Iovis, `` day of Jupiter ''. Friday : Old English Frīgedæg ( pronounced ( ˈfriːjedæj ) ), meaning the day of the Anglo - Saxon goddess Fríge. The Norse name for the planet Venus was Friggjarstjarna, ' Frigg 's star '. It is based on the Latin dies Veneris, `` Day of Venus ''. Saturday : the only day of the week to retain its Roman origin in English, 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 dies Saturni, `` Day of Saturn ''. The Scandinavian Lørdag / Lördag deviates significantly as it has no reference to either the Norse or the Roman pantheon ; it derives from old Norse laugardagr, literally `` washing - day ''. The German Sonnabend ( mainly used in northern and eastern Germany ) and the Low German words Sünnavend mean `` Sunday Eve '', the German word Samstag ( mainly used in southern and western Germany ) derives from the name for Shabbat.

Knowledge of Greek astrology existed since about the 2nd century BC, but references to the vāra occur somewhat later, during the Gupta period ( Yājñavalkya Smṛti, c. 3rd to 5th century ), i.e. at roughly the same period the system was introduced in the Roman Empire.

The Chinese seem to have adopted the seven - day week from the Hellenistic system by the 4th century, although by which route is not entirely clear. It was again transmitted to China in the 8th century by Manichaeans, via the country of Kang ( a Central Asian polity near Samarkand ). The 4th - century date, according to the Cihai encyclopedia, is due to a reference to Fan Ning ( 範 寧 / 范 宁 ), an astrologer of the Jin Dynasty. The renewed adoption from Manichaeans in the 8th century ( Tang Dynasty ) is documented with the writings of the Chinese Buddhist monk Yi Jing 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 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.

Numbered days of the week Days numbered from Sunday See also : Feria Sunday comes first in order in calendars shown in the table below. In the Judeo - Christian or Abrahamic tradition, the first day of the week is Sunday. Biblical Sabbath ( corresponding to Saturday ), when God rested from six - day Creation, made the day following 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 Galician, due to Martin 's influence, are the only Romance languages in which the names of the days come from numbers rather than planetary names. 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.

The Slavic, Baltic and Uralic languages ( except Finnish and partially Estonian ) adopted numbering but took Monday rather than Sunday as the `` first day ''. This convention is also found in some Austronesian languages whose speakers were converted to Christianity by European missionaries. In Slavic languages, some of the names correspond to numerals after Sunday : compare Russian vtornik `` Tuesday '' and vtoroj `` the following '', chetverg `` Thursday '' and chetvertyj `` the fourth '', pyatnitsa `` Friday '' and pyatyj `` the fifth '' ; see also the Notes.

The modern Chinese names for the days of the week are based on a simple numerical sequence. The word for ' week ' ( which is literally translated to ' star day ' ) is followed by a number indicating the day : ' Monday ' is literally ' star day one ', ' Tuesday ' is ' star day two ', etc. The exception is Sunday, where rì ( 日 ), meaning ' sun ' or ' day ', is used instead of a number. Day Monday Tuesday Wednesday Thursday Friday Saturday Sunday Standard Chinese 星期 一 Xīngqīyī 星期二 Xīngqí'èr 星期三 Xīngqīsān 星期四 Xīngqīsì 星期五 Xīngqīwǔ 星期六 Xīngqīliù 星期日 Xīngqīrì Days numbered from Saturday In Swahili, the day begins at sunrise rather than sunset, and so are offset by twelve hours from the Arabic and Hebrew calendar. 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.

Sunday uses the Arabic name, which is based on numbering, 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.
