Mercury retrograde in 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 and ends within Capricorn 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 and ends within Taurus season.

Mercury retrograde in 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 and ends within Virgo season.

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.
…and back into Sagittarius
In Sagittarius the retrograde affects travel, study and beliefs. Journeys are delayed, paperwork for visas or courses gets stuck, and opinions stated too confidently need walking back. It suits revisiting plans for the bigger picture before committing to them.
It begins in Sagittarius season and ends in
Capricorn season.

Mars

Jupiter
in Leo —
Dec 14 to Jan 3, 1991 (20 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 1990
Mercury through the zodiac in 1990
Every sign Mercury occupies during 1990, 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.
