The problem with the Meme is saying that Saturday (laugardagr in Old Norse) have someting to do with Lokis day. Laugardagr should be translated to “bathing day”, since the Old Norse word “Laug” means bath. Source: https://ordnet.dk/ods/ordbog?query=l%C3%B8rdag&tab=for
The Meme is correct when talking about Tuesday, Wednesday, Thursday and Friday (although it’s not clear from the sources if Friday is Frigg or Freya). It’s also clear that Monday and Sunday is The Day of the Moon and The day of the Sun. The names seem to be a translation of the Latin names for the day. If the Old Norse peoples saw these days as days pertain to the deified moon and sun we really don’t know, but it does seem likely. Source http://denstoredanske.dk/Nordisk_Mytologi/Begreber/ugedage
