Events, invitations and who is actually free Coming by Holi
Eleven lines of the specification that are genuinely one thing. Recurring events and time zones are where the real difficulty sits, and both are solved problems reached for from a library rather than reasoned about from first principles — an event repeating on the last working day of a month, moved once, in a zone that shifts its offset twice a year, is the kind of thing that must never be written by hand twice. Syncing to an outside calendar needs that provider’s credentials and is a constraint; a calendar of this system’s own is not.

Events & Recurrence
A dated entry with the people it concerns, and the rules for one that repeats. A single occurrence of a repeating event can be moved or cancelled without disturbing the rest of the series, which sounds small and is the difference between a calendar people trust and one they quietly stop using.
Invitations, Availability & Time Zones
Asking somebody to an event, tracking whether they answered, and showing when they are genuinely free. Every time is stored as an absolute moment and displayed in the reader’s own zone, so a meeting set across two countries means the same instant to both of them and survives a daylight-saving change landing between the booking and the day.
Shared & Team Calendars
A calendar belonging to a group rather than a person, with control over who may see a full entry and who may see only that the time is taken. The distinction matters: a team usually needs to know somebody is busy without being told what about.
Resource Booking
The things that get double-booked as often as people do — a room, a vehicle, a machine, a piece of equipment. Held as a bookable record with the same conflict checking an invitation gets, because a room with two meetings in it is the same failure as a person with two.
