Pretty Useless Until It’s Useful: 50-Year Calendar Keyring

The 50-year calendar keyring is one of those things you don't need but wouldn't mind having. As the name implies, it's a keyring and a calendar at the same time. But it's unlike those typical calendar keychains that are only useful for a year or two tops, because there's only so many days and weeks you can attach to it.

That's what makes the 50-year Calendar Keyring different: instead of tacking on a calendar, it comes with a mechanism that basically functions as a 50-year calendar. That's right: keys may come and go, and so will cars, apartments, and friends--but this keychain is here to stay.
