Ancient cultures celebrated 8 Solar Holidays over the course of a year. Half of those Solar Holidays are still acknowledged as the beginning of each of the 4 seasons which divide the year into 4 equal parts giving rise to the name Quarter Holidays. Not surprisingly, the 4 celebrations that are celebrated halfway between the start of the 4 seasons are called Cross Quarter Days.
Lammas or Loaf Mass Day, celebrated on August 1st, is a Christian holiday where loaves of bread made from the new grains are blessed. This first harvest festival celebrates the beginning of gathering the crops. The earliest berries and grains are ready in late summer.
