Does anyone understand what this person is trying to convey here?

I have created a system which can be used to coordinate all of the people interested in thing X to be able to meet/play/discuss/experience X at the same exact time as all other users of the system interested in thing X. All with just a simple math formula, no internet connection required.

Most Useful Use Cases
1.) Fan Coordination for Niche Interests: For obscure games or media (e.g., "XONOTIC"), high-RDV days can prompt spontaneous group sessions every few weeks, months, or even years, without needing calendars or servers.
2.) Media Reconsumption and Group Watches: Assign RDVs to movies, books, or videos (e.g., "SHREK_2001") for synchronized rewatches. RDVT adds timing for live streams or premieres, useful for content creators scheduling events at pseudorandom but shared times.
3.) Remembrance and Appreciation Days: Create special days for artists, events, or personal milestones (e.g., "YEAR_2000" or "HARRY_POTTER_SMOKES_WEED_Cdfkq2Nmb3c"). This could extend to historical events or personal tasks, providing a lightweight alternative to traditional calendars.
4.) Personal Reminder Systems: Integrate into apps or browser extensions to notify users about bookmarks or to-do items probabilistically, reducing notification fatigue. For instance, a threshold of RDV ≥ 2 ensures infrequent but timely prompts.
5.) Live Events and Scheduling: With RDVT, coordinate real-time activities like video calls or streams at exact UTC times on reminder days. This is especially useful for global teams or communities avoiding time zone conflicts.

I have done extensive research and I can with certainty say nothing even similar to this exists out there. I would be thrilled to explain why this algorithm/system I have created solves something that doesn't have a solution yet. What would you like to know about it?

Google Calendar? Microsoft Outlook Reminders? Alarm clocks?

Unlike standard tools to mentioned above where you manually pick a date to remind yourself (or a group), Randevu uses a math formula to pick the dates for you.
Here is the difference in a short:
Google Calendar/Outlook/Alarms: You explicitly say, "Remind me (and my team) to play XONOTIC on Friday at 8 PM." This requires planning and sending invites.
Randevu: You and a thousand strangers (or however many people put XONOTIC onto their list of this they wanna get reminded of) all agree on a secret keyword (like "XONOTIC", but can be literally any word you can think of). Every day, you all run a script that rolls a mathematical dice based on that keyword and today's date. If the dice rolls a "6" for everyone on the same day, you all get reminded to play at the exact same moment - without ever talking to each other or using a central server. And this algorithm works in such a way people will ALWAYS get the same dice rolls (even without the internet connection). It's also not based on dice rolls, but I thought it would be a decent analogy.
Summary: It is a decentralized coordination engine. Instead of a server storing an appointment, the "appointment" exists mathematically in the combination of a text string and the date. This allows infinite groups of people to synchronize their behavior (like playing a dead multiplayer game, or watching a long forgotten YT video or movie) without a leader, a schedule, or a central database. And each person can chose which objects to have on their list and how often they would like each of them to be featured (have a special day).
