Be A Retronaut

Retronaut? It's as easy as clicking on the link -- in fact, that's how you get there, for visits to real pasts and pasts that never happened.

In one of the pre-1800 links, there's an image of a perpetual calendar. (With an addendum of sunrise/sunset tables and computatation of interest...likely intended for bankers, businessmen, or sea-captains.)

The calendar portion is still useful, by my least for the next 23 years.
