Sign 11 of 12 in the horoscope

Are you really an Aquarius?

By the horoscope, yes, and your sign stays yours. The stars behind it have quietly moved along, though: Aquarius runs from 20 January to 18 February 2026, and on those dates the Sun passes through Capricornus and Aquarius. This is the sky behind your sign.

Why the sky behind Aquarius has moved

Aquarius’s dates were set more than two thousand years ago, pinned to the March equinox, when the signs took their names from the constellations the Sun was crossing. Since then Earth’s slow wobble, called precession, has carried the equinox about a twelfth of the way round the sky, roughly one day’s worth every seventy years. Your sign has kept its dates, and the stars behind them have simply moved along: that is why the Sun now spends Aquarius’s days in Capricornus and Aquarius.

These dates are computed for 2026 from the constellation boundaries the International Astronomical Union fixed in 1930. A boundary can fall a day earlier or later in another year, so for the particular day, and hour, you were born the calculator will check it for you.
