Format Differences

Gotchas

• Note package name is @stacksjs/calendar-api (not @stacksjs/calendar)
• ICS export returns file content (not a URL) — serve as .ics download
• All-day events use date-only format, ignoring time components
• Timezone handling varies by provider — ICS includes VTIMEZONE block
• Google Calendar uses UTC format in URLs
• For task scheduling (cron), use @stacksjs/scheduler instead
• ICS generates a unique UID per event for calendar deduplication
