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.

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.

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 1977
Every sign Mercury occupies during 1977, 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.
