A person in week one of bootcamp in the navy, P-days are the processing days where you learn that it is ACTUALLY possible to fall asleep standing up and that no matter what you do, it's wrong. You also learn what a knife hand looks like pointed straight at your throat while you quiver in your newly issued PT gear with your valuables sock sticking out of your sweatpants and your go fasters on your feet. Welcome to hell recruit.
In summary, P days: Literally the worst week of your life you'll ever experience

The Friday before Thanksgiving, an annual holiday.

This day originated in Nov. 2019 when office coworkers decided that the earliest Christmas music could be played and Christmas decorations could be set up in the office was the Friday before Thanksgiving. It was decided that this should become an annual holiday, similar to Pi Day (3/14) but better! This day should be celebrated annually by decorating offices for Christmas and eating all things that start with the letter P (pancakes, pretzels, pie, pizza, pumpkin, popcorn, etc.). Enjoy your P Day!
I can't wait to decorate the office and eat pizza, pancakes and pie on P Day this year!

Short for "preparation day." Missionaries have one day of the week set aside for preparatory activities such as housecleaning, shopping, laundry, letter-writing, and, oh yes, recreation.

Officially, missionaries are supposed to wear their suits and ties on p-day, except when participating in sporting activities. In reality, there are no ties in sight on p-day. Officially, p-day starts at 6:30 am and ends at 6:30 pm. In reality, the fun often starts at 10:30 the night before, and doesn't end until until late in the p-day night.
Bill: Hey Elder John, what are you going to do tomorrow?
Elder John: Well, it's my P-Day so I'm going to go get some groceries, clean my apartment and go play some football!

June 1st, the day that companies around the world cease all operations and focus on the gays and change their logo to rainbow-themed. Schools also stop teaching their kids and focus on the gays too.
Dude, even I'M gay, and I don't celebrate P-Day like they do. It's fuckin' weird. God help us all.
