OpenCal shows your free time from all your calendars on one link. People see when you are free, never your events.
What it is
OpenCal: the homepage
OpenCal displays your available times from all connected calendars through a single shareable link. Visitors can see when you are free up to 90 days ahead in Week, 2-week or Month views, along with your name and chosen profile details, but never see event titles, places or guest information. You can connect multiple Google and Microsoft accounts, iCloud, Teams, Outlook and any other calendar via .ics feed. When multiple people share links, the system compares calendars to show only mutually free times.

Quick answers
Is it free?
Yes. OpenCal is free to use.
What do people see on my link?
They see your open times up to 90 days ahead in Week, 2-week or Month views. They also see your name and any profile details you choose to show, but they never see event titles, places or guests.
Which calendars can I connect?
You can connect several Google and Microsoft accounts and an iCloud account. You can read a Teams or Outlook calendar from your desktop screen using the built-in reader. You can read Outlook on the web with the browser extension and add any other calendar with its .ics feed link.
How does the other person see times for both of us?
They sign in with Google or Microsoft on your link. The server compares both calendars and sends each of you only the shared free times.
Does OpenCal send email?
Guest bookings are the only bookings that receive email from OpenCal. A visitor who books your link as a guest gets one confirmation email with a link to add the meeting to their calendar. OpenCal sends no other email unless you enable adding bookings to Google or Outlook in Settings.
