What to do during
Mercury retrograde.

A practical, phase-by-phase checklist for Mercury retrograde: what to finish before the station on February 9, 2027 at 17:36 UTC, what to review until March 3, 2027 at 12:32 UTC, and what to relaunch after post-shadow ends March 23, 2027 at 14:58 UTC.

First, the dates

Advice is only useful against a calendar. The next Mercury retrograde begins February 9, 2027 at 17:36 UTC and ends March 3, 2027 at 12:32 UTC, in Pisces and Aquarius. Pre-shadow starts January 25, 2027 at 18:58 UTC, the cazimi falls on February 18, 2027 at 16:39 UTC, and post-shadow ends March 23, 2027 at 14:58 UTC. Those times are UTC; the cycle page converts them to your clock. Nothing below is a prediction. It is the traditional way of using a known three-week window, and it works as a planning rhythm whether or not you give the planet any influence.

Before the station: finish and back up

During the retrograde: review, revise, reconnect

The cazimi: one clear day

In the middle of the retrograde Mercury passes exactly between Earth and the Sun. In the tradition this cazimi is the one bright window inside the retrograde: a day to set a single clear intention, make the decision you have been circling, or start the conversation that matters. For this cycle it is February 18, 2027 at 16:39 UTC.

After the station direct: relaunch, slowly

What not to do

Do not cancel your life for three weeks. Mercury is retrograde about one week in five, and in shadow for several more, so a calendar that avoids all of it avoids most of the year. The useful habit is smaller: know the dates, and in those weeks slow the send button down. Cazimi's today page and the iPhone app tell you which phase you are in, to the minute.

Born during a retrograde?

About one person in five was born while Mercury was retrograde. The birthday checker looks it up against every cycle from 1900 to 2050, including the shadow periods.
