Happy May Day! This annual celebration has its roots in astronomy as 1 of 4 cross-quarter days. Dancing around a maypole is a traditional May Day celebration.
The 1st May full moon happens on May 1. It'll look full on the nights before and after that, too. The 2nd May full moon - a Blue Moon - will fall on May 30-31.
Visible planets and night sky guide. This evening, the bulging gibbous moon - approaching full - hangs near Spica, the brightest star in Virgo the Maiden.
