It's quite clever.
I demand a pedantic correction to "in the Year of our Proleptic Gregorian Calendar". The Gregorian calendar has an epoch dating from before it started, which is just confusing if you're counting years. Interestingly, leap years seem to have been regularised right around the epoch. Sources conflict as to whether 4 was a leap year or not (under the Julian calendar in use at the time), but generally agree that there were no Julian-calendar leap years before then, and that AD 8 and all multiples of 4 thereafter, until the Gregorian calendar was introduced, were leap years. (The need for multiple-of-4 leap years was recognised several years earlier, but previous experiments with the calendar had accidentally introduced too many leap years, so the calendar ran without leap years for several years to compensate.) -- ais523
