Moodle's unified calendar is a brilliant foundation for everything related to events and provides deep integration for a lot of activities as well.
This block provides an additional interface for the existing calendar entries. It aims to be an additional alternative to block_upcomingevents and block_calendar.
The best location to put the block is the dashboard, especially on Moodle 4.0 because of courses being shifted to a separate page. Using this block, the dashboard essentially provides an overview about the student's day, week or month.
