2010 Ecological Calendar Engagement Calendar

Chris Hardman's ECOlogical Calendar will shake up your world and your concept of time. Designed for use in the Northern Hemisphere, this engagement calendar, like the wall version, presents information on seasonally visible stars, the phases of the moon and tides, the ratios of darkness and light, the seasonal behavior of Earth's creatures, and a host of other details about the natural world. The familiar Gregorian days, dates, weeks and months, as well as international holidays, telephone codes, and time differences, are also included in this highly functional calendar, but don't be surprised if you begin thinking differently about time and our place in it!
