The Third and Fifth Easters are the most important days of the Easter cycle. Pisces 28 is the Day of Action to Resurrection, linked to the Cretaceous-Paleogene extinction event. This fifth Easter Sunday (V), also known as Cetus Day, falls on the 112th day of the Gaian year. Chapter 112 of the Gaiad is read today, telling how the K-Pg extinction destroyed dinosaur civilization but cleared the way for mammals and birds to inherit the world.
