title: Convert "using excel method" numeric value in date - java
body: <p>I have an integer that when I put on Google Sheets, it represents the date 14/10/1911 (integer value is 4305).</p>
  
  <p>I need to do this same conversion in my code using Java. So I'll have an array of integer that goes down by a factor of 1 (like 4305, 4304, 4303...) and I need to convert these integers into date (14/10/1911, 13/10/1911, 12/10/1911...) using the same method that excel/sheets uses.</p>
  
  <p>Any ideas?</p>
  
  <p>Thanks</p>
