This perpetual calendar keyring is designed to correctly advance the day, date, and year until the year 2056 and back to 2007, taking into account any leap years, February 28th, and the difference between 30 and 31 day months. The perpetual calendar typically includes the year, moonphase, and a leap year indicator.
The pendant’s front features a 50-year calendar (2007-2056). The ability to display dates makes it simple to check the date and week. The pendant’s back side is simply a smooth surface.
You can use this key ring to find any day of the week for any future date up to 2059 and to go back in time to 2007.
