Thank you for the detailed feedback and for trying out the Calendar beta—we’re really glad to hear it aligns well with your business needs. We understand how critical custom repeat events are, especially options like flexible intervals and open-ended schedules similar to Google Calendar, and we agree these features are essential for broader adoption. At the moment, we’re treating the beta phase much like an NBI clearance process (https://nbiappointmentonline.ph/): before rolling out full functionality, we need to complete the necessary checks, validations, and safeguards to ensure reliability, security, and compliance at scale. Rest assured, enhanced custom calendar features are already on our roadmap, and your input helps prioritize them as we move toward a fully cleared and production-ready release. Thank you again for your support and patience.

I don't know about other countries, but here in the U.S. we have events that may be scheduled for "first Sunday" or "fourth Saturday," or "last Monday" in only certain months.

I have not found Proton Calendar to be able to handle such patterns, nor will it support such patterns in events imported or subscribed from other calendars.

This is a dealbreaker for me, and forces me to use Google Calendar for all calendar uses -- a crime against humanity I can assure you.

Please fix this oversight.

I want to be able to create repeating events with the options available in Outlook's "Appointment recusance" options, that would probably cover most people's requirements.

Then if you added to ability to enter a list of dates for frequent but irregularly occurring appointments, that would probably "nail it".

This is one of a number of features that is currently preventing me from switching to use Proton Calendar.

This would permit gatheringds that happedned at sporadic interims to be entered in a solitary exchange toward the start of every year/month and so forth.

How hard would it be to implement a "list dates" function when enter events in calender? This would allow meetings that occurred at irregular intervals to be entered in a single transaction at the beginning of each year/month etc.

Agreed, This is what I came here to request also.

This is a feature in Outlook as well, at the very least it should copy the functionality from both of these services.
