Written / hashed together by Alan Hart
If you're interested: The date entry field uses HTML 5's input field type="date" calendar picker. (For non HTML 5 compliant browsers jQuery calendar picker is used.)
Examples: 19th December 1999 Date plus 6 days | 1st April 2015 Date plus 99 days
20th April 1982 Date plus 12000 days
