How often is Mercury retrograde?

Usually three times a year (occasionally four), each lasting about three weeks.

Should I avoid signing a contract during Mercury retrograde?

There's no evidence that outcomes change. Read carefully, confirm the details, and sign when the terms are right.

What is the Mercury retrograde shadow?

The weeks before and after the retrograde when Mercury moves through the same degrees it will cover, or has covered, while retrograde.

Is Mercury actually moving backward?

No. It's an apparent motion caused by Earth and Mercury passing each other in their orbits.

What is Mercury retrograde, and does it affect work?

Updated September 25, 2026

Mercury retrograde is a period, about three times a year for roughly three weeks each, when Mercury appears to move backward against the stars as seen from Earth. Nothing about Mercury's real orbit changes; it's an optical effect of Earth overtaking a faster inner planet. There is no scientific evidence that it causes misunderstandings or broken laptops, but many people use it as a useful cue to slow down and double-check their work.

What's actually happening

Mercury orbits the Sun in 88 days. As Earth and Mercury pass each other, Mercury's position against the zodiac seems to stop, reverse for about 21–24 days, stop again and move forward. Astrologers call the stopping points stations. The weeks just before and after, when Mercury is covering the same degrees, are called the shadow.

Why astrologers link it to work

In traditional astrology Mercury rules communication, contracts, paperwork, travel and technology. Retrograde periods are read as a time to **re-**do things: review, revise, reconnect, renegotiate. You don't need to believe that the sky causes anything to find that framing practical.

Practical ways to use it

Re-read before you send. Add a second pass to important emails and proposals.
Confirm details in writing. Dates, deliverables and prices.
Finish before you start. Clear backlogs, edit drafts, close loose threads.
Leave buffer. Put an extra day on deadlines that depend on other people.
Don't freeze. Signing a good contract or launching a ready product isn't something to delay because of a date on a calendar.
