# SYNCDATE

> Two-way calendar sync for Google Calendar, Microsoft Outlook, CalDAV providers (iCloud, Fastmail, Nextcloud, and any standards-compliant CalDAV server), and iCal feeds. Free forever for 2 calendars.

SYNCDATE keeps events synchronized across multiple calendar providers automatically. Personal events show as "Busy" on work calendars — no details exposed. Webhook-driven sync delivers Google and Outlook changes in ~4 seconds; CalDAV and iCal use scheduled polling.
