Mercury retrograde, 2023.

Computed in America/New York (Eastern Time); every time prints its UTC offset.

Mercury appears to backtrack three or four times a year. Tradition — the tradition Orrery scores with — flags those weeks for do-overs in what Mercury governs: messages, deals, signatures. Not doom; drag. The stations below are computed to the minute from JPL ephemeris data, which is why they don’t round to tidy dates the way listicles do.

What the retrograde touches

Orrery weighs Mercury retrograde most heavily for words and commitments: see sending a pitch, signing a contract, and the hard conversation — each month page shows the retrograde inside the days it drags on. The full rulebook is in Method.
