  the status of specific days or weeks from the default Non-
  Work to Work or from Work to Non-Work.

  major project milestones, by choosing Special from the Mark
  submenu.  You can mark both Work and Non-Work days or
  weeks as Special.  To mark a day or week, click on the day or
  the week number to select it, then choose one of the following
  items from the Mark submenu:
