We should honor this day be eating the most perfect of foods, which of course is pie. I'll take a pi of pie in fact if someone else will take the other pi. (trig nerd joke)
In fact, we should eat Apple pie in honor of Isaac Newton and then eat the pie at 3:00 PM local time where you are.
Why you ask? Because 3:00 PM is 15:00 Military time so you would be eating pie at 3.1415
