/* Surgery countdown calendar

   Currently set to count down to August 29, 2022.
   You can change that on line 23.

   This is designed to be a small MacOS widget,
   the parameter should be your time zone's offset
   (https://www.timeanddate.com/time/map/)
   from UTC, for the US, that is
  -04:00 for EDT/AST
  -05:00 for CDT
  -06:00 for MDT
  -07:00 for PDT
  -08:00 for AKDT
  -10:00 for HDT
