What an ingress is — and why 2026 is unusual

An ingress is the instant a planet’s position along the ecliptic — the Sun’s apparent path, divided into twelve 30° signs — crosses from one sign into the next. It’s a precisely computable astronomical event: the timestamps below mark the moment each planet’s apparent geocentric longitude passes a multiple of 30°. The Sun does this like clockwork around the 19th–23rd of every month (those twelve crossings are also how we get the equinoxes and solstices). Mercury and Venus change signs every few weeks, Mars every couple of months — and because the inner planets retrograde, some of them cross the same cusp twice, backing into the previous sign before re-entering. Those retrograde re-entries are marked “Rx” in the table.

In astrology, an ingress changes the weather. A planet is said to express itself through the style of the sign it occupies, so the day Mars trades Aries for Taurus, the collective mode of drive and conflict is read as shifting from sprint to siege. The slower the planet, the bigger the chapter break — which is what makes 2026 remarkable. This year Neptune enters Aries to stay (first time since 1861), Uranus settles into Gemini (first time since 1941), Saturn returns to Aries for its multi-year stay, and Jupiter strides into Leo mid-year. Three outer planets changing era in a single year is rare; astrologers read it as the start of a genuinely new cycle rather than another lap of the old one.

How to use the table: the outer-planet rows set the multi-year backdrop; the Sun rows give you the familiar zodiac-season rhythm; the Mercury, Venus, and Mars rows time the fast-moving mood of weeks and months. An ingress lands hardest when the sign involved is prominent in your own birth chart — the sign on your Ascendant, your Sun, or your Moon — because the planet is entering one of your houses, not just a sign in the abstract.
