No, it does not. You will need to use the built-in AOSP calendar (accessible through a side-loaded launcher) or download a calendar app like KashCal ( KashCal review by paxristi - #4 by el-lobo-loco ) or Etar ( Etar - OpenSource Calendar review by Leslie98 ).
On anothe note, I must admit I’ve quit using DAVx5 myself and have switched to using Homie ( Homie Family Organizer review by oyvind ), where my calendars are all now hosted and synced.
