Most Human Design charts use the tropical zodiac: twelve equal signs that begin at the March equinox. It follows the seasons, and the constellations it is named after have drifted about 31 degrees away from it. From today the app measures against the sky itself. The mechanics you know stay the same. The positions change.

Every line says what it was and what it is now.
BeforeCharts used the tropical zodiac, like almost every Human Design tool: twelve equal 30-degree signs counted from the March equinox.
NowCharts are measured against the real constellations: thirteen of them, unequal, with boundaries drawn along the Sun’s path by the Midpoint Method of Athen Chimenti. Both moments stay, your birth and the exact 88-degree design moment.
BeforeA tropical and sidereal toggle was once promised for Plus.
NowThere is one sky, on every plan. A switch beside the claim would undo the claim.
BeforeThe wheel drew twelve equal signs.
NowThe wheel draws the thirteen constellations at their real widths, so you can see Virgo stretch and Scorpio and Ophiuchus sit side by side.
A row on the chart, transits and relationships pages counts how many of your activations fall in the thirteenth constellation.
A shared chart is a fixed snapshot, so it carries a sky label rather than a switch. Someone you send it to knows exactly what they are looking at.
Both people are calculated against the same sky, so a pair can never be compared across two different frames.
BeforeArticles described a tropical-only app.
NowWhy your chart is read against the real sky, how it is calculated, and why it looks different from another site, in English, German and Russian.
BeforeA dormant sidereal path would have drawn tropical sign names on a sidereal wheel.
NowThe wheel and the chart always agree on which constellation a planet is in.
