    2011 , 2013 , 2014 , 2015 , 2017 , 2018 , 2019: 365 days

    2012 , 2016 , 2020: 366 days

    7 * 365 + 3 * 366 =>

    7 * 365 + 3 * 365 + 3 * 1 =>

    10 * 365 + 3 =>

    3653

    Now, subtract the first 12 days of 2011

    3653 - 12 = 3641

    Subtract the 31 days of December 2020

    3641 - 31 = 3610

    Subtract the 30 days of November 2020

    3580

    Add the first 15 days of November 2020

    3595

      Excel can be used as a double check 
      enter the two dates 
      subtract the newer date from the older date and 
      subtract one from the answer, because Excel math include the enddate     
      (A1) 1/12/2011
      (A2) 11/16/2020
      (A3) = (a2-a1)-1 = 3595
