Update "Get System Time" node to give us the "day of the week" (Monday, Tuesday, etc)

I would love to be able to pull from the “Get System Time” node the actual “day of the week” it is aka Monday, Tuesday, Wednesday, Thursday, Friday, Saturday, or Sunday. I have a fun effect idea in mind that would be greatly facilitated by this. Else, I have to manually calculate the day of the week based on one reference date in the past and calculate forward keeping leap years in mind…
