I've decided instead to call this Happy Sheela Day!
Sheelas can be found all over the British Isles, but her most prolific iconography has been found in Ireland. The Irish remember her as the 'Old Woman Creatress', the Hag-Mother of All Humanity. During the early Celtic conversion happening there during this time period, this unapologetically sexual fertility symbol appeared on early churches all over the British Isles, as if to make a bridge between the ancient religion and the new one. She is often found grinning, with her vulva joyfully spread wide- as if to say "Here, behold the source the life!". In modern times, the Sheela is thought to bestow good luck when her yoni is stroked and women frequently also employ touching her yoni as a charm to bestow fertility and bring ease during birth.
HAPPY SHEELA DAY!
