Hey Maurice!   
      
    MK> Actually the calculation should have been (2342-100) and not   
    MK> (2342-99).   
      
   No.  My first calculation is correct and 2024-07-29 is the '99 bottles of beer   
   on the wall' day, which makes 2024-11-05 the 'No more bottles of beer on the   
   wall' day as it should be.  Also your handy-dandy calendar confirms my   
   calaculation.  As a follow up here is the '99 bottles of beer on the wall'   
   calendar for 2019-01-01;   
      
   -={ cal -n5 9 2018 }=-
