Sorry that this is so late! I’m still here!
Apparently this phrase was first used in a political ad when Margaret Thatcher was elected prime minister of England, back on May 4, 1979. However, that was more or less forgotten until a translator misspoke in 2005. His quick translation into German of “May the force be with you” reads more like “On May the 4th we are with you.” The phrase stuck, and Star Wars fans everywhere have now adopted May 4 as their own special celebration, Star Wars Day, or, for the more adventurous, Intergalactic Star Wars Day.
“Praise him, sun and moon;
praise him, all you shining stars.”
