Mercury enters Libra

Mercury crosses into Libra on 18 September 2025 at 09:58 UTC.

An ingress is simply a body passing 0° of a sign, but it marks a genuine change of register: Mercury in Libra operates through air means and at a cardinal tempo. Mercury moves quickly and changes how conversation, negotiation and thinking are conducted.

Libra is ruled by Venus, so for as long as Mercury is here its behaviour is coloured by that planet as well as by its own nature.
