I put my dentist appointment in my calendar and my boss said it was fine but next time I should write it in the calender as a request so he could approve it. Then I told him that it wasn't a request, I'm just notifying him that I won't be there. It's at least two weeks out, so he has time to plan. Also – does anyone have a way of writing it so he can acknowledge it, but without me using the word request.
