Our contract with the real estate agent was from the first week of August 2015 to the first part of February 2016. The house was empty from mid-Aug 2015 until renters moved in on April 1, 2016. The first rent was received in March 2016. I assume that there are no personal use days in 2016, but can we count 366 rental days? It was certainly available for rent on January 1, although it was not advertised as such.
