What this period actually is
Between March 15, 2025 and April 7, 2025 Mercury moves back through 12.8 degrees of the zodiac, from 9°35' Aries to 26°50' Pisces, without changing its own direction at any point. Mercury is an inner planet, so this happens as it swings between Earth and the Sun; the loop it appears to trace from 9°35' Aries back to 26°50' Pisces is Earth's own motion showing up in the line of sight.
The mechanism behind the Mercury station of March 15, 2025 is the same one described in what retrograde motion is. Read astrologically, the convention is that Mercury — thinking, wording, contracts and short journeys — turns inward between March 15, 2025 and April 7, 2025, which is a habit of reading rather than a claim about the sky.
The dates in full
Station retrograde: March 15, 2025 at 9°35' Aries, 06:46 UTC. Station direct: April 7, 2025 at 26°50' Pisces, 11:08 UTC. It begins in Aries and backs into Pisces, crossing the boundary between 9°35' Aries and 26°50' Pisces rather than working one stretch of a single sign.
Mercury first reaches 26°50' Pisces — the degree it will retrograde back to — on March 1, 2025, and does not clear 9°35' Aries, the degree it stationed at, until April 26, 2025, so counting both shadows the passage runs 56 days rather than 23.
What the period is good for
For the 23 days between March 15, 2025 and April 7, 2025 the workable version of the advice is narrow: re-read anything before signing it, back up what you cannot replace, and expect arrangements to need confirming twice.
If one thing is worth timing around the stretch that ends April 7, 2025, it is launching a product, signing a lease or buying the device you will depend on for three years — not because the sky forbids it, but because a marked period is a reasonable prompt to check work you would otherwise wave through. Treating the whole of March 15, 2025 to April 7, 2025 as a general curse is the version worth ignoring.
