Aries season begins on March 21 and ends on April 19. You may see these dates listed a day earlier or later on other sites — that’s not an error. The Sun doesn’t change signs at the same clock time every year, so the exact start and end can shift by about a day depending on the year and your time zone. For almost everyone, March 21–April 19 is exactly right. Born right on the edge? See the cusp section below.
Born right at the edge of Aries? You were born on a cusp — the changeover point between two signs. March 21 sits on the Pisces–Aries cusp; April 19 sits on the Aries–Taurus cusp. Astrologically, there’s no such thing as being “half and half” — you’re fully one sign or the other. The only way to know for certain is to check the exact moment the Sun changed signs in your birth year, since a boundary birthday can fall under either sign depending on the year and hour you were born.
Every sign divides into three decans of roughly ten days, each with a sub-ruler that shades the core personality:
As a fire, cardinal sign ruled by Mars, Aries is bold, energetic, and pioneering — the zodiac’s fearless initiator.

Aries pairs most naturally with fellow fire signs Leo and Sagittarius — shared energy, confidence, and a love of a challenge — plus air signs Gemini and Aquarius, who fuel Aries’s ideas rather than slow them down. Aries and Libra, sitting opposite each other on the wheel, often balance well precisely because they’re so different — Libra brings diplomacy, Aries brings drive. Aries and Scorpio can be intensely passionate, though both signs’ strong wills sometimes clash for control. Cancer and Capricorn tend to need the most patience as matches, since their slower, more cautious pace can frustrate Aries’s need for speed.

April 19 is the last day of Aries. The Sun moves into Taurus the following day, April 20.
They’re close but not identical. The Sun enters each sign at a specific time, not a fixed calendar moment, so the exact date can shift by about a day depending on the year and your time zone — mainly relevant if your birthday sits right on March 21 or April 19.
Pisces comes just before Aries, and Taurus comes just after.
Leo and Sagittarius are often considered Aries’s strongest long-term matches, thanks to shared fire-sign energy and confidence. Gemini and Aquarius also build fast, exciting connections with Aries.
