Earthman's Almanac

HAPPY NEW YEAR!!!

December 22 CE is the first day of the new year in the Terrannum (the interplanetary calendar for Earth). The Terrannum (TA) records time and events in space exploration from a terrestrial point of view, but with a heliocentric and galacticentric perspective. The calendar begins with the dawn of the Space Age, the launch and orbit of Sputnik 1. The Terrannum is also the core calendar of Earthman's Almanac (EA). December 22, 2017 CE is Geminia 1, 62 TA, the first day of the sixty-second year of the Terrannum. So, happy new year EA.

Earthman's Almanac 61 (boxed edition) is now available. Look for it at Mac's Backs on Coventry in Cleveland Hts., soon!

Earthman's Almanac 62 (multi-boxed edition) will be available late 2018.
