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.

Some have referred to this article for the connection between Loki and Laugardagr: http://honortheroots.com/laugardagr/?fbclid=IwAR2UIwD9SIxwIVpaKOMa_KXPgUMlaBBf2FFHdY0OKUCdkUVrFRd7bexZi1k
The article don’t really add anything serious to the debate. The argument in the article comes down to the suggestion that the name of the day was changed from Loki’s day to Laugardagr because the Christians didn’t want to have a day named after Loki and the article continues “Some scholars have suggested that Laugardagr was actually named after Loki. “Loke,” being an Lokis Dayabbreviation and later adaptation from the word “Lodurr” – suggesting that Laugardagr is also a name that is based upon a one of our gods.”
I have not been able to identify who these ”scholars” are. There are some scholars think that the god named Lodurr is the same as Loki. It is not a general accepted theory, but it could be. We don’t really know. But I have not heard about any scholar that connect the name Lodurr to the Laugar in Laugardagr. The two words doesn’t seem to have anything in common with each other, except they both begins with an “L”
