February Cross-Quarter

Halfway between a solstice and an equinox: the astronomical moment behind Imbolc.

The Sun reaches ecliptic longitude 315°, halfway from the December Solstice to the March Equinox. It is the astronomical moment behind the Gaelic festival of Imbolc (IM-bolk), traditionally kept on Feb 1.

The name

Cross-quarter days fall halfway between a solstice and an equinox. Like the solstices and equinoxes, they are named for their month, so the names work in both hemispheres.

Precision

A sharp moment: the time is meaningful to the minute.

Every year

Between 1900 and 2100 it comes as early as February 3 at 01:44 UTC (2097) and as late as February 5 at 05:24 UTC (1904).Dates wobble through each four-year leap cycle and creep earlier across a century, until a skipped leap day, as in 1900 and 2100, sets them back.
