Launching/showing calendar from the menu bar Is there any app that would allow me to preview the calendar from the menu bar (i.e. show calendar with a single click)?

It's all I need, I don't even need to open calendar from that app, though it would be nice.

  Day-O is a simple menu bar clock replacement with a simple calendar
  for your Mac. It’s free, as-is (which means I’m not providing support,
  taking feature requests, addressing perceived inadequacies or
  releasing the source code).
