Recently, I've come to realize this isn't really a book (it's a luni-solar calendar). Yes, I did write a book to keep it company - a collection of true stories and poems that can keep you company too - but in truth what's shown here is a sample luni-solar calendar (demonstrated on the left-hand pages) with explanations about how it works and an excavation into the calendar we use today. I found an interesting and appropriate factoid for each calendar page - mostly having to do with space or the origins of names.
The companion book is on the opposing pages - seasonally appropriate and including holiday traditions, folklore, bits of history, more starry science and/or lore, a few recipes, and even a game (at the very back of the book). It takes a peek at what's known of a European calendar in use previously, explores the names of our current weekdays and the old Anglish gods behind them, and even digs a little at Europe's long buried earth-friendly roots. The whole collection was born of the author's longing for a more organic way of telling time.
