Zexuna is the sixth month of the year in the Vetus calendar, and consists of five nine-day weeks.
Zexuna begins (astrologically) with the sun in the sign of Flamma and ends in the sign of Felis. Astronomically speaking, the sun begins in the constellation of Clavis and ends in the constellation of Flamma.
Zexuna is Archaic for "sixth moon," because the months in the Vetus calendar are lunar, and Zexuna marks the sixth moon phase for the year.
Seasonally, Zexuna is the second half of summer for those in the northern hemisphere, and the second half of winter for those in the southern hemisphere. It is preceded by Quinuna and succeeded by Sepuna.
