Sharing a date is the obvious part. The strategic upside is the customer-visible space that remains in the calendar and the response path back to your systems.

Why this exists
The first ICS file is easy. The thousandth is a system.
Client incompatibility
Calendar clients parse line folding, descriptions, and time zone blocks differently.
Recurrence maintenance
Daylight saving transitions and exceptions can shift events across global teams.
Content changes wait
Small offer or description updates should not require an engineering release.
Trapped calendar RSVPs
Responses disappear into client silos unless they are routed back to your systems.

A calendar operation is one generated ICS file or one RSVP response successfully processed and forwarded. RSVP counts once even when forwarded to multiple destinations; rejected, duplicate, or failed responses with no forward are not counted.
AI-assisted translation adds one billable operation for each translated event.
