Quick Answer
Use Schedule Trigger to run on a cadence, Google Calendar to find upcoming events, IF to filter them, and Slack or email to send concise reminders.
Problem Pattern
Calendar reminders become noisy when they run in the wrong timezone, include canceled events, or send generic messages that do not help the recipient prepare.
Key Facts

- Event source
- Google Calendar provides event data for the selected calendar.
- Filter
- IF should remove canceled, private, or irrelevant events.
- Message

Recommended Steps
- Choose a schedule and timezone for scanning upcoming events.
- Fetch events from the target calendar for the next reminder window.
- Filter canceled, private, or all-day events if they should not alert.
- Use Set to format the reminder fields.

Verification

Why did the reminder fire at the wrong time?
Check workflow timezone, calendar timezone, and the date window used in the calendar query.
Should all-day events be included?
Usually no for meeting reminders. Treat all-day events as a separate workflow or filter them out.
