What remains for a new entrant is usually an unrelated word that teaches the market nothing, or a respelling that will look dated by the time the product matures. This is the third option. Calendarial is a coined adjective on a root everybody knows, which means the first five letters do the explaining while the invented ending makes it ownable. Say it once and people know the subject.

Calendar standards and open scheduling protocols are genuine technical work handled by open bodies, and calendaring standards in particular have active ongoing development. That’s the .org reading and it’s a real one.

The consumer reading works too, for a scheduling app, a booking product or an events platform.
