August Cross-Quarter
Halfway between a solstice and an equinox: the astronomical moment behind Lughnasadh.
The Sun reaches ecliptic longitude 135°, halfway from the June Solstice to the September Equinox. It is the astronomical moment behind the Gaelic festival of Lughnasadh (LOO-nuh-suh), traditionally kept on Aug 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 August 6 at 09:55 UTC (2096) and as late as August 8 at 18:16 UTC (1903).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.
