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.
…and back into Capricorn
In Capricorn the retrograde hits career plans, authority and long-term structures. Deadlines slip, approvals are delayed and managers change their minds. It is traditionally used for reviewing goals and reorganizing rather than for starting new ventures.
It begins in Capricorn season and ends in
Aquarius season.

Mercury retrograde in Taurus
In Taurus the retrograde lands on money, possessions and practical plans. Purchases get returned, payments are delayed, and decisions about property or savings are revisited. It is traditionally a good window for reviewing budgets rather than making large new commitments.
It begins in Taurus season and ends in
Gemini season.
No other planet is retrograde during this period, which is unusual.

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.
…and back into Virgo
In Virgo, Mercury's other home sign, the retrograde focuses on work routines, health and detail. Schedules unravel, small errors multiply, and systems that seemed fine reveal flaws. It is ideal for audits, decluttering and fixing processes before starting anything new.
It begins in Virgo season and ends in
Libra season.

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.

Mercury through the zodiac in 1917
Every sign Mercury occupies during 1917, 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.
