I have put various birthdays and holiday's on my outlook calendar.
To make the number's bold on the calendar I put that I was busy.
However, I cannot make the holiday/birthday show up in my appointment
list to remind me unless I mark it as being less than an all day
event. Is it possible to make holidays be listed and bold without
showing it as busy and only a period of time?

It seems to me that anything whose "Show time as" value is "busy" or "out of
office" will cause a date to be bolded. Anything showing "free" won't.
This doesn't appear to depend on the duration. It works that way both for
all-day events and for events with explicit start and end times.
