<Li> 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". </Li> <Li> 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 . </Li> <Table> <Tr> <Th> Day: (see Irregularities) </Th> <Th> Sunday Sunna / Sól </Th> <Th> Monday Mona / Máni </Th> <Th> Tuesday Tiw / Tyr </Th> <Th> Wednesday Woden / Odin </Th> <Th> Thursday Thunor / Thor </Th> <Th> Friday Frige or Freya </Th> <Th> Saturday Saturn </Th> </Tr> <Tr> <Th> Proto - Germanic </Th> <Td> * Sunnōniz dagaz </Td> <Td> * Mēniniz dagaz </Td> <Td> * Tīwas dagaz, * Þingsas dagaz </Td> <Td> * Wōdanas dagaz </Td> <Td> * Þunras dagaz </Td> <Td> * Frijjōz dagaz </Td> <Td> * Saturnas dagaz, * Laugōz dagaz </Td> </Tr> <Tr> <Th> Old English </Th> <Td> Sunnandæg </Td> <Td> Mōnandæg </Td> <Td> Tīwesdæg </Td> <Td> Wōdnesdæg </Td> <Td> Þunresdæg </Td> <Td> Frīgedæg </Td> <Td> Sæternesdæg </Td> </Tr> <Tr> <Th> Old Saxon </Th> <Td> Sunnundag </Td> <Td> * Mānundag </Td> <Td> * Tiuwesdag, * Thingesdag </Td> <Td> Wōdanesdag </Td> <Td> * Thunaresdag </Td> <Td> Frīadag </Td> <Td> * Sunnunāƀand, * Satarnesdag </Td> </Tr> <Tr> <Th> Old High German </Th> <Td> Sunnûntag </Td> <Td> Mânetag </Td> <Td> Zîestag </Td> <Td> Wuotanestag </Td> <Td> Donarestag </Td> <Td> Frîjatag </Td> <Td> Sunnûnâband, Sambaztag </Td> </Tr> <Tr> <Th> Middle Low German </Th> <Td> Sunnedag </Td> <Td> Manedag </Td> <Td> Dingesdag </Td> <Td> Wodenesdag </Td> <Td> Donersdag </Td> <Td> Vrīdag </Td> <Td> Sunnenavend, Satersdag </Td> </Tr> <Tr> <Th> German </Th> <Td> Sonntag </Td> <Td> Montag </Td> <Td> Dienstag, Ziestag (Alemannic German) </Td> <Td> Mittwoch (older Wutenstag) </Td> <Td> Donnerstag </Td> <Td> Freitag </Td> <Td> Sonnabend, Samstag </Td> </Tr> <Tr> <Th> Yiddish </Th> <Td> Zuntik--זונטיק </Td> <Td> Montik--מאנטיק </Td> <Td> Dinstik--דינסטיק </Td> <Td> Mitvokh--מיטוואך </Td> <Td> Donershtik--דאנערשטיק </Td> <Td> Fraytik--פרײַטיק </Td> <Td> Shabbes--שבת </Td> </Tr> <Tr> <Th> Scots </Th> <Td> Saubath, Sunday </Td> <Td> Monanday </Td> <Td> Tysday </Td> <Td> Wadensday </Td> <Td> Fuirsday </Td> <Td> Friday </Td> <Td> Seturday </Td> </Tr> <Tr> <Th> Dutch </Th> <Td> zondag </Td> <Td> maandag </Td> <Td> dinsdag </Td> <Td> woensdag </Td> <Td> donderdag </Td> <Td> vrijdag </Td> <Td> zaterdag </Td> </Tr> <Tr> <Th> Afrikaans </Th> <Td> Sondag </Td> <Td> Maandag </Td> <Td> Dinsdag </Td> <Td> Woensdag </Td> <Td> Donderdag </Td> <Td> Vrydag </Td> <Td> Saterdag </Td> </Tr> <Tr> <Th> Luxembourgish </Th> <Td> Sonndeg </Td> <Td> Méindeg </Td> <Td> Dënschdeg </Td> <Td> Mëttwoch </Td> <Td> Donneschdeg </Td> <Td> Freideg </Td> <Td> Samschdeg </Td> </Tr> <Tr> <Th> West Frisian </Th> <Td> Snein </Td> <Td> Moandei </Td> <Td> Tiisdei </Td> <Td> Woansdei </Td> <Td> Tongersdei </Td> <Td> Freed </Td> <Td> Sneon, Saterdei </Td> </Tr> <Tr> <Th> Low Saxon </Th> <Td> Sünndag </Td> <Td> Maandag </Td> <Td> Dingsdag </Td> <Td> Middeweek, Goonsdag (rarely Woonsdag) </Td> <Td> Dünnerdag </Td> <Td> Freedag </Td> <Td> Sünnavend, Saterdag </Td> </Tr> <Tr> <Th> Old Norse </Th> <Td> sunnudagr </Td> <Td> mánadagr </Td> <Td> tysdagr </Td> <Td> óðinsdagr </Td> <Td> þórsdagr </Td> <Td> frjádagr </Td> <Td> laugardagr, sunnunótt </Td> </Tr> <Tr> <Th> Faroese </Th> <Td> sunnudagur </Td> <Td> mánadagur </Td> <Td> týsdagur </Td> <Td> mikudagur, ónsdagur (Suðuroy) </Td> <Td> hósdagur / tórsdagur (Suðuroy) </Td> <Td> fríggjadagur </Td> <Td> leygardagur </Td> </Tr> <Tr> <Th> Icelandic </Th> <Td> sunnudagur </Td> <Td> mánudagur </Td> <Td> þriðjudagur </Td> <Td> miðvikudagur </Td> <Td> fimmtudagur </Td> <Td> föstudagur </Td> <Td> laugardagur </Td> </Tr> <Tr> <Th> Norwegian Bokmål </Th> <Td> søndag </Td> <Td> mandag </Td> <Td> tirsdag </Td> <Td> onsdag </Td> <Td> torsdag </Td> <Td> fredag </Td> <Td> lørdag </Td> </Tr> <Tr> <Th> Norwegian Nynorsk </Th> <Td> sundag / søndag </Td> <Td> måndag </Td> <Td> tysdag </Td> <Td> onsdag </Td> <Td> torsdag </Td> <Td> fredag </Td> <Td> laurdag </Td> </Tr> <Tr> <Th> Danish </Th> <Td> søndag </Td> <Td> mandag </Td> <Td> tirsdag </Td> <Td> onsdag </Td> <Td> torsdag </Td> <Td> fredag </Td> <Td> lørdag </Td> </Tr> <Tr> <Th> Swedish </Th> <Td> söndag </Td> <Td> måndag </Td> <Td> tisdag </Td> <Td> onsdag </Td> <Td> torsdag </Td> <Td> fredag </Td> <Td> lördag </Td> </Tr> <Tr> <Th> Elfdalian </Th> <Td> sunndag </Td> <Td> mondag </Td> <Td> tisdag </Td> <Td> ųosdag </Td> <Td> tųosdag </Td> <Td> frjådag </Td> <Td> lovdag </Td> </Tr> </Table> <Tr> <Th> Day: (see Irregularities) </Th> <Th> Sunday Sunna / Sól </Th> <Th> Monday Mona / Máni </Th> <Th> Tuesday Tiw / Tyr </Th> <Th> Wednesday Woden / Odin </Th> <Th> Thursday Thunor / Thor </Th> <Th> Friday Frige or Freya </Th> <Th> Saturday Saturn </Th> </Tr>
