October 24, 2026 had an unusual trick: written 10/24/26, its numbers satisfied the Pythagorean theorem. The next qualifying date is in 2105. Reddit users, naturally, decided that waiting was optional if they could redesign the calendar.
Why the date works
Ten squared is 100, twenty-four squared is 576, and their sum is 676—exactly twenty-six squared. The numbers can describe the sides of a right triangle. The 26 comes from the last two digits of 2026. Switching month and day to 24/10/26 changes nothing mathematically. Seattle Universal Math Museum actually scheduled a Pythagorean Palooza for October 24 and identified March 4, 2105 (3, 4, 05) as the next date. The equation was real enough to get its own museum celebration.
Reactions people actually posted
Among real comments visible on the Reddit thread 'next one is 2105' was 'May the 10/24th be with you,' turning a famous Star Wars greeting into a geometry pun. Another commenter promised to create a calendar in which this was the only date. Nobody would miss the occasion again; birthdays, rent and every other day would need new jobs. A different participant figured living to 101 might be entirely achievable.
The correction and the late post
Other commenters distinguished the return of the same written date in a later century from the next different date satisfying the equation. The corrected poster admitted that they mainly wanted an excuse to post the joke. In a separate October 25 discussion, someone asked why the image had not been posted on the actual day. That original post is removed, so only its public comments support the observation.
Original comedy, not a comment
Chair: 'Nearly 79 years until the next one.' Planner: 'Make every day October 24.' Mathematician: 'Then calendars stop working.' Planner: 'But every day passes geometry.' Accountant: 'When are invoices due?' Planner: 'October 24. Forever.' Accountant: 'We've turned a math festival into a financial emergency.' This is original fictional dialogue, not a Reddit exchange.
Conclusion
The numbers work: 100 + 576 = 676. The proposed one-day calendar does not. Pythagoras established a theorem about triangles, not a subscription that lets us cancel tomorrow.
