Maandag

The English noun Monday derived sometime before 1200 from monedæi, which itself developed from Old English (around 1000) mōnandæg and mōndæg (literally meaning "day of the moon"), which is cognate to other Germanic languages, including Old Frisian mōnadeig, Middle Low German and Middle Dutch mānendach (modern Dutch Maandag), Old High German mānetag (modern German Montag), and Old Norse mānadagr (Swedish and Norwegian nynorsk måndag, Danish and Norwegian bokmål mandag). The Germanic term is a Germanic interpretation of Latin lunae dies ("day of the moon").

Monday, Monday, can't trust that day
Monday, Monday, sometimes it just turns out that way
Oh Monday mornin', you gave me no warning of what was to be
Oh Monday, Monday, how could you leave and not take me?

(Mama’s en Papa’s)

Monday morning feels so bad
Everybody seems to nag me
Come on Tuesday I feel better
Even my old man looks good
Wednesday just won't go
Thursday goes too slow
I've got Friday on my mind
