You can serve calendars in ICal format from your web application on-the fly or you can save it to the disk as an *.ical file and serve the static file. Then people can add it to their calendar application and see the events you list.

The modules in use:

Data::ICal
Data::ICal::Entry::Event
DateTime
DateTime::Duration
DateTime::Format::ICal

This code generates two events. The first one has a beginning and ending date. The second one has a beginninng and a duration. It also includes a link to Zoom as the "location".
