Equinoxes, Solstices and Cross-Quarter Days 5.42

Calculates dates and times for equinoxes, solstices and cross-quarter days.

Software to calculate accurate dates and times for equinoxes, solstices and the Celtic cross-quarter days. The cross-quarter days are those midway between the equinoxes and solstices. For example, Imbolc is midway between the northern winter solstice and the northern spring equinox (a.k.a. the northern vernal equinox), and Beltane is midway between the northern spring equinox and the northern summer solstice.

Equinoxes, Solstices and Cross-Quarter Days 5.42 full description

This software calculates accurate dates and times for equinoxes, solstices and the Celtic cross-quarter days (Imbolc, Beltane, Lughnassad and Samhain). The cross-quarter days are those midway between the equinoxes and solstices. For example, Imbolc is midway between the northern winter solstice and the northern spring equinox (a.k.a. the northern vernal equinox), and Beltane is midway between the northern spring equinox and the northern summer solstice. When we attempt to define the cross-quarter days more exactly we find that there are two interpretations, and thus two methods of calculation, which give slightly different results. These two methods are called the 'mean sun' method and the 'true sun' method. The mean sun method assumes (erroneously) that the Earth moves at a constant speed in a circular orbit around the Sun. The true sun method calculates a cross-quarter day based on the time at which the Earth reaches that point in its orbit which is spatially (geometrically) exactly halfway between its positions at the solstice (or equinox) and the subsequent equinox (or solstice).
