365 is nearly prime (5×73), which is why our months are such a mess. But 360 has 24 divisors; enough to build clean hierarchies like 6-day weeks, 5-week months, 3-month quarters, 4 quarters/year + 5 holidays (6 on leap years). Every month identical, every date always the same weekday.

Built a small tool to explore all valid factorizations across different bases (336, 350, 354, 360, 364, 365), with a Gregorian comparison view that really highlights how arbitrary the current system is. Radial year visualization, work/rest analysis, season alignment, etc.

I've also added historical calendars, like the French Revolutionary calendar that was created in a similar sentiment.

Let me know what I should add, or if you catch a bug/mistaken logic!17:T753,Hi HN,

I made Voidful, a kind-of-anti-social network where users can yell into the void to see how many other people are yelling the same thing. If you yell something similar, this is considered an "echo" and you gain access to a chat room about that topic with other users being notified.

Currently when users yell into the same void they are brought into a chat together, but this is somewhat of an MVP. In the future that chat may have guard rails related to the topic, rewards left by other users, and possibly more!

A key concept is that users can never enumerate or list the voids, as otherwise it will likely turn into a vanity war like traditional social media, which in my opinion is at the all-time-high for gamification. I am trying to remove the incentive to say random stuff to make
