Translation:The newspaper comes on Mondays and Wednesdays.
Almost all the days of the week come originally from Scandinavia.
Monday: Day of the Moon
Tuesday: Day of Tiwaz (God of the Sky)
Wednesday: Day of Odin (Wodin) (King of the Gods)
Thursday: Day of Thor (God of Thunder)
Friday: Day of Frey (Frigg, Freya, etc) (Goddess of the Earth)
Saturday: In English this means "Day of Saturn" but the Scandinavian version, "lördag" means "day of the baths"
Sunday: Day of the Sun
Yeah. That's because languages such as Norse, Swedish, Danish, German, Dutch, English, Afrikaans and some more all have the same roots (which are Germanic). Another good example for this is the word "hound". In Swedish it's "hund" and in German it's "Hund" (which are the languages I speak and in the other languages it should be similar). They're written and pronounced very much alike.
It's good to see the "roots" of your mother language (Dutch for me), it sometimes makes it easier to understand things (however sometimes it isn't alike at all) :) måndag = maandag; tisdag = dinsdag; onsdag (Odin for Scandinavia) = woensdag (Wodan for "Germania"); torsdag (Thor) = donderdag (Donar)... hund = hond; katt = kat; bi = bij...
It's really up to the speaker. As a general rule, the slower and more formal you speak, the more likely you are to pronounce the full word. And if the next word starts in a vowel, you're also more likely to pronounce the full word. Most commonly in everyday speech, though, the k sound is swallowed.
