Most of today's pagans religiously follow the phases of the moon, and the various witches' almanacs gear their celebrations and/or observances in line with the dates of the Gregorian calendar in order to synchronise their monthly observances. If we follow our pagan year merely for celebration and observance it makes little difference when we hold our feast days and festivals but if our magical operations need to connect with the Old Ways of our Ancestors then we need to align with the old calendars that were brought to these islands by the Romans, the Celts and the Anglo-Saxons. These formal calendars are the nearest guide we have to help us in understanding the customs and beliefs of our indigenous ancestors. The Roman legionnaires garrisoned in Britain came from all over the Europe and they would have brought their religions and beliefs with them from the far flung corners of the Empire; as would the incoming Celts, Danes and Anglo-Saxons whose influence would have eventually been grafted onto older, indigenous stock especially when similar celebrations fell around the solstices and equinoxes. Great book! Love the fair days and events in England that still hold with old tradition and the ideas for honouring days. Definitely a book to have on the shelf and look at every couple of days.
