Wife out of the blue asked: "What day is Easter?"
Me: "Huh? It keeps moving around as it's tied to the new moon, or something..."

Vaguely remembered there was a formula to calculate the date, but was puzzled by wife's interest as Easter Bunny and eggs AFAIK haven't really taken off yet in Japan. Insidious effects of Tokyo Disneyland propaganda?🤔
Found the date (5 April 2026) and the Butcher-Meeus algorithm. [1,2]

Just a quick #calculation: 🤔

...in my two-room #apartment, I have four rooms: bathroom, living room, bedroom, and kitchen, plus a balcony.

-> That makes five #doors in total! ⁉️

So, with two doorposts per #door, there's a good chance, purely mathematically speaking, that I'll stub all my toes, just in my own apartment! 😜

-> Does that explain why theorists always seem so depressed?
-> Just as a quick calculation, anyway! 😆

The #corpus #calculation with the final big number for my version. Aiming at about $5M raise and #home 18 forever. Have to rerun numbers against double blind sources and against known gold standard document. But the method is the thing. It is merely the same vehicle that the #billionaires use to pin you down. You bet the market, not stocks, then cannot be a target because they do not shit in their own pool.
#Homelessness is below survival line, not just #poverty line.
