Mercury retrograde in Aquarius
In Aquarius the retrograde falls on technology, groups and future plans. Software glitches, group chats full of misunderstandings and stalled community projects are typical. It suits updating systems, reconnecting with old friends and rethinking long-range ideas.
It begins in Aquarius season and ends in
Pisces season.

Mercury retrograde in Gemini
In Gemini, one of Mercury's own signs, the retrograde is at its most talkative and scattered: crossed wires, double-booked diaries, lost chargers and conversations that go round in circles. It rewards editing, rereading and catching up with people you lost touch with.
It begins and ends within Gemini season.

Mercury retrograde in Libra
In Libra the retrograde centers on relationships, agreements and contracts. Negotiations stall or reopen, misunderstandings arise in partnerships, and people from the past reappear. It favors renegotiating terms and clarifying what was assumed rather than signing new deals.
It begins and ends within Libra season.
Also retrograde at the same time
Uranus
in Aries —
Sep 25 to Oct 17, 1929 (21 days of overlap)
Jupiter

Oct 5 to Oct 17, 1929 (12 days of overlap)
Both dates are computed from the planet’s apparent motion, not taken from a
table. A retrograde begins the moment its daily movement against the stars turns
negative, and that moment is findable to the hour.
Computed for 1929
Mercury through the zodiac in 1929
Every sign Mercury occupies during 1929, with the dates it enters and leaves. A sign that
appears twice means the planet backed into the previous sign during a retrograde and crossed again.
