The four cross-quarter days of the Eamon year are times of celebration across Addar, marked by festivals, ceremonies, and feasts. They occur at the midpoints between the four cardinal days (the two equinoxes and two solstices, sometimes called "quarter days").

The four are listed below in bold, along with their surrounding cardinal days and the dates on which they most often fall in the Ovidoric calendar.
