So I thought finally they would fix this. After years of waiting, sending in complaints to Apple, they would finally allow me to have my international settings as U.S. and my calendar week start on Monday, not Sunday. IT STILL ISN'T FIXED! What's more is that you can set iCloud's calendar to start on Monday! So... BusyCal is set for Monday! iCloud is set for Monday! iPad and iPhone... Sorry, you must start on Sunday in the United States! Why Apple can't change this boggles my mind? I just don't understand. It's probably the easiest code change in the history of the universe!
