If you’ve ever felt that tossing a calendar a year is wasteful, this is one way to conserve paper. It will not only serve well as a paper weight, but it will work for 50 years. For some of you, you’d never have to buy a calendar again. This 50 year calendar makes sure to calculate for leap years, and begins in 2006 and goes until 2055. To work the calendar you line up the year and month at the top and then the weekday and the date pops up on its own at the bottom. I don’t know how anyone keep from losing this thing over the span of 50 years. At least it’s not expensive though, you can pick it up for $10.19 on Amazon.
