The people of the Industrial Kingdoms observe the lunar caldenar, consisting of 364 days in a year. Each of its twelve months is divided into exactly 28 days with each week corresponding to a phase of the moon. The remaining days are divded between four week-long festivals held at the beginning of each season. Holidays are usually celebrated in or around these festivals. Finally, the coming year is given a special name on All Saints Day, usually to honour a saint, but sometimes it carries a different significance.
