Mercury enters Aquarius

Mercury crosses into Aquarius on 20 January 2026 at 16:31 UTC.

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

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