INTRODUCTION The dates listed for the festivals should not be taken too seriously, since calendars in the Greek and Roman worlds were quite chaotic before the calendar reform of Julius Caesar. Months were lunar and were often out of step with the solar year. In Greece each city had its own months (over 300 are known), and often picked different times to begin the year. The dates shown here are based on the Julian calendar and the "standard" months of Athens. Nevertheless, the dates may be taken a guide to the time of year of a festival. For the Imbolc festival season I have listed the major or most characteristic festivals first, and the lesser festivals later, even though the dates may be out of order.
