The first day of October (October 1st) which is similar to the first day of April (see April Fool's Day) where lies are told under the excuse of an observed holiday. First observed by Nintendo after their absolute joke of a Super Smash Bros. Ultimate reveal on October 1st, 2020.
Person 1: Hey, what prank did you pull for October Fool's Day?
Person 2: I announced a bad character for Smash!
Person 1: Wow, so original...

Holiday that celebrates science, nature, and logic instead of religion. Created on the Birthday of Neil deGrasse Tyson (October 5th). To celebrate this holiday you eat a lot of bacon and enjoy science and nature. You also give gifts to friends and family that promote science, nature and logic.
"What did Mike get you for Logic Day (October 5th) Susan?" "He bought me a life-size model of the Solar System!"

"This Logic Day (October 5th) we celebrated science and nature by building a greenhouse out of old windows and planting vegetables inside"

"For Logic Day (October 5th) this year we are having a big block party"
"What should I bring?"
