How do I calculate the days my property was rented for 2018? When does the first day of the tax year 2018 begin?

[majesticco2013]

My property was rented from January 1st, 2018 to December 31st, 2018.  It was not rented from January 1st, 2019 to February 16th, 2019.  What date do I begin calculating days it was rented and what day do I end the total on for the tax year of 2018?

The first day of the normal 2018 tax year is January 1, 2018. The last day of the normal 2018 tax year is December 31, 2018. The number of days between and including 1/1/2018 and 12/31/2018 is 365.

Based on the information you have provide, the number of days is 365. The days not rented in 2019 do not count.
