title: Convert time (given in days since YYYY) into readable time format
body: <p>I need help with converting time to a readable format. My <code>time</code> array (has 580 elements) is # of days since January 1st, 1900. How do I convert that to a normal time format (ie mm-dd-yyyy)? </p>
  
  <p>For example, input time is 43,887 and output should read 02-27-2020 after adding it to Jan 1, 1900.</p>
  
  <p>Thank you!</p>
