Samstag: the etymologists don't agree. A minority thinks it comes from Saturn's day (like in English), the majority think it comes from dies sabbati and is short for Sabbat Day.

The Northern German say Sonnabend, that is Sunday Eve.

Robo, thanks for the effort, but I must seriously (grin) protest Twosdays, for that is too near to the old word and may violate some feelings. Sevensday also is unacceptable because it prefers one group, the Seventh day adventists.

So up to the next protest it should be Onesdays, Threesday, Foursday, Fivesday, Sixsday, Eigthday, Ninethday.

On second thought, Three alludes to the Christian trinity, One alludes to the Muslim and Jewish idea of God...
