Astronomical Cross Quarter Dates 2015 to 2019

There are two sets of dates which can be used to determine when the cross quarter days fall. The first is simply a set of fixed dates, although those dates can vary slightly from person to person, tradition to tradition. Fixed days are perhaps more commonly used. With fixed dates Imbolc is always from sundown on the 1st to 2nd of February, or Samhain is sundown on October 31st to sundown on November 1st - or whatever dates one chooses to use, the same dates will be used every year.

However, there is also the method where the dates are calculated by the position of the solstices and equinoxes of the year. For example, Imbolc would be the exact midpoint between the winter solstice and spring equinox, and Beltaine would be the midpoint between the spring equinox and summer solstice, and so on. Since the solstices and equinoxes can shift slightly from year to year, so can the cross quarter dates when using this method.

The following is a chart of cross quarter dates based on the solstices and equinoxes for 2015 to 2019, all based on Eastern Standard Time.

  1. There are actually three ways to calculate this, Allie. The third way has to do with the Sun and Moon in the Fixed Signs. ;)

    1. Admittedly, I don't really have much interest in astrology, but the last time I saw that explained it seemed to work out to the same dates as above. Is that not the case?
