@julian Else maybe the dawning of the age of aquarius?
For the new kids on the block who may not grok the cultural reference:
The expression Age of Aquarius in popular culture usually refers to the heyday of the hippie and New Age movements in the 1960s and 1970s.
The 1967 musical Hair, with its opening song "Aquarius" and the line "This is the dawning of the Age of Aquarius", brought the Aquarian age concept to the attention of audiences worldwide. However, the song further defines this dawning of the age within the first lines: "When the Moon is in the seventh house and Jupiter aligns with Mars, then peace will guide the planets and love will steer the stars". Astrologer Neil Spencer denounced the lyrics as "astrological gibberish", noting that Jupiter aligns with Mars several times a year and the Moon is in the 7th House for two hours every day.
These lines are considered by critics to be poetic license, though some people have taken them literally. An example is the identification of Valentine's Day 2009 as the "perfect alignment to support our collective manifestation of love and peace and dawning of the Age of Aquarius".
The music festival commonly known as Woodstock was billed as "An Aquarian Exposition".
