The stars behind Gemini
In 2026, the sign Gemini runs from 21 May to 21 June. The Sun starts that time in front of the stars of Taurus and then crosses into Gemini (21 June).
The signs were named for the constellations about 2000 years ago, when the March equinox was in the stars of Aries. The Earth's axis wobbles slowly, a movement called precession, and it has carried the equinox almost a whole sign along the Sun's path. Today the Sun is in front of Pisces at the March equinox.
