Mercury takes 1 year through the zodiac, never more than 28° from the sun, so visits repeat on that rhythm. Born outside these windows? Then your Mercury is elsewhere: cast your chart to see where.

The style: Sagittarius
The open road, meaning chased past the map's edge. As a fire mutable sign ruled by Jupiter, Sagittarius shapes Mercury's function to be expansive, honest, restless. The full portrait lives in the Sagittarius sign guide.
Dignity: how Mercury fares here
By traditional essential dignity, Mercury in Sagittarius is in detriment (away from home) (this is a verifiable rule of the tradition, not an opinion). Dignity describes how comfortably the planet's function operates in this sign. It is one input among many. A planet in fall with strong aspects by house and orb can outperform a dignified one that nothing supports.
The house decides where it shows up
Two people with Mercury in Sagittarius can live it differently, because the house is the stage. Mercury in Sagittarius in the 10th plays out in career and public standing. In the 4th, at home and in family. Same style, different rooms. That is why your birth time matters more than any sign lookup. The rising sign guide explains how the houses get drawn.
