Remove the default of All Day for new entries. Very few events are all day and it trips up inexperienced users like grandmothers
Not sure why all calendar entries default to all day. This reflects the minority. It’s also quite annoying especially as when you deselect all day the time of the appointment defaults to 00:00. I can’t see many people finding that useful. Should be 9am or something.
Also when you remove all day it rolls back to previous day
