NOTE ON FRIDAY BEING 'UNLUCKY'
From: Today I Found Out
Some theorize that Friday being unlucky predated Christianity.
The name “Friday” was chosen in honour of the Norse goddess Frigg, also known as Freyja, who was the multi-talented goddess of love, beauty, wisdom, war, death, and magic.
Teutonic people are thought to have considered the day extremely unlucky, especially for weddings, due in part to the lovely goddess the day was named for. Later, the Christian church attempted to demonize the goddess, so that may or may not be a contributing factor as well.
Whatever the case, despite these quite old origin theories, well documented instances of the notion that Friday was popularly considered unlucky among the masses doesn’t seem to have popped up until around the mid-17th century. Within the next two centuries after that, the idea continued to spread and by the 19th century was nearly ubiquitous in certain cultures.
