The problem
Manually distributing holiday event files or asking users to subscribe leads to patchy adoption and outdated information. There is no built-in mechanism to force updates or removals for all users at once.
How it works
- Maintain a canonical list of holiday events centrally.
- Use domain-wide delegation to impersonate each user in the domain.
- Insert or update events in each user's primary calendar using the Calendar API.
- Track event IDs to allow future updates or removals without duplication.
What changes
Every user sees the same up-to-date set of holiday events in their primary calendar, with changes rolled out automatically.
Questions people ask
Can this update or remove existing holiday events?
Yes, but only if you track and reuse the original eventId. Otherwise, you risk leaving orphaned or duplicate entries.
How long does it take for changes to appear for all users?
Propagation is immediate at the API level, but client devices may cache calendars and only refresh periodically, so some users will not see updates until their next sync.
Want this built?
This is a pattern we run in production. We will set up the delegation and build this on top of it — $500 per hour, most of it working the same day.
