Have you heard of a Perpetual Calendar? Have you seen any of these disks like in the pictures below? Nope, it's not a DVD, it's called a perpetual calendar.

The ones in the pictures are those that I am using for our Project Management at work. Date Finders or Perpetual Calendars are very useful in planning and I've used it for the planning of my own wedding.


You can use it to expedite a certain orders that you've made with your supplier without bothering to flip those desktop calendars. Just rotate the first dial to get to the duration or date that you want. You can even take a look at another year calendar, for example the one that I have here are for up to 2015 calendars so I could check on the day a certain date fall on the year that I want. Perfect for planning that special occassions of yours.
