Doomsday Method | Mental Game vs Bug Identifier ° BugSpot AI

Someone tells you the date they were born. You tell them it was a Monday. That is a real skill, it takes about a week to learn, and this app teaches it end to end. The Doomsday algorithm — invented by the mathematician John Conway — turns any date into its weekday using arithmetic small enough to finish while someone is still saying the date. No lookup. No phone. No calendar. LEARN 48 lessons across 11 chapters, in three parts 178 checkpoint questions. You answer in your head, then check yourself against the worked reasoning — nothing is graded, and nothing is rushed Interactive calendars, anchor tables and step-by-step walkthroughs inside the lessons themselves Mnemonics that stick: 4/4, 6/6, 8/8, 10/10, 12/12, and "9-to-5 at the 7-Eleven" Six different ways to work the year offset. Pick the one your head likes, and every worked explanation in the app is rewritten in it Seven Extras: why the method works, Easter and the computus, the Julian calendar, Conway's own shortcuts, the record holders, and full reference tables A cheatsheet with every anchor and every offset on one screen TRAIN 10 drills: weekday numbers, counting in sevens, leap years, century anchors, the year offset, month doomsdays, day counting, reverse dates, Julian dates and Easter Five stars a drill, earned by answering cleanly — right, and inside that drill's target time Nothing cuts you off mid-question, and training never costs you rating PLAY Classic — endless real dates, at your own pace, with no clock at all Daily Challenge — five dates drawn from the day itself, identical for every player on earth, one attempt a day Time Attack — two minutes, as many dates as you can, ten seconds off for every miss Choose your range: 2000–2099, 1800–2199, or the whole Gregorian calendar from 1583 to 2599 YOUR PROGRESS A Doomsday Rating that rises when you are right and quick, and never pays for a guess Accuracy and speed over time, your rating history, and a 12-week activity calendar Game Center leaderboards for today's challenge and the global rating, friends included BUILT PROPERLY No account, no sign-up, no ads Works offline Every number in every lesson is re-derived by a checker that shares no code with the app, so an explanation cannot drift from the answer it gives Analytics are opt-in, pseudonymous and on EU servers.
