Mercury retrograde in Aries
In Aries the retrograde tends to show up as hasty words and rushed decisions coming back for review. Messages sent in anger, plans launched without checking and arguments started on impulse are the classic material. The useful version is slower starts: finish the draft, reread it, then press send.
…and back into Pisces
In Pisces the retrograde blurs details and heightens intuition. Instructions are misread, dates are forgotten and communication relies on feeling rather than fact. It favors rest, creative reflection and double-checking anything that must be exact.
It begins in Pisces season and ends in
Aries season.

Mercury retrograde in Leo
In Leo the retrograde touches creative projects, self-expression and romance. Work you shelved asks to be finished, performances need rehearsing again, and an old flame may reappear. It is a good window for revising creative work rather than launching it.
…and back into Cancer
In Cancer the retrograde turns toward home, family and memory. Old family conversations resurface, house moves hit snags, and people revisit the past more than usual. It suits sorting photographs, repairing the home and having the talk you postponed with a relative.
It begins in Cancer season and ends in
Leo season.

Mercury retrograde in Scorpio
In Scorpio the retrograde goes digging. Secrets surface, shared finances need re-examining, and conversations turn intense. It suits research, therapy and honest reckonings, and it punishes suspicion that runs ahead of the facts.
It begins and ends within Scorpio 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.
Computed for 1940
Mercury through the zodiac in 1940
Every sign Mercury occupies during 1940, 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.
