When does Aries start and end?
Aries season begins on March 21 and ends on April 19. You may see the dates listed a day earlier or later on other sites, and 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, the March 21 to April 19 range is exactly right. If your birthday lands on the very first or very last day, read the cusp section below.
Were you born on the Aries cusp?
Born right at the edge of Aries? Then you were born on a cusp — the changeover point between two signs. The first day of Aries (March 21) sits on the Pisces–Aries cusp, and the last day (April 19) sits on the Aries–Taurus cusp. Astrologically there’s no such thing as being “half and half,” though — you are still 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, because a birthday on the boundary can fall under either sign depending on the year and the hour you were born. If you were born on March 21 or April 19, a quick birth-chart lookup will settle it for good.
The three decans of Aries
Every sign is divided into three decans of roughly ten days, each with a sub-ruler that adds its own flavour to the core Aries personality. Here’s where you fall:
- First decan (March 21–30): the purest expression of Aries, doubly ruled by Mars — the most classic Aries traits.
- Second decan (March 31–April 9): shaded by Leo (sub-ruled by the Sun), adding a Leo twist to your Aries core.
- Third decan (April 10–19): shaded by Sagittarius (sub-ruled by Jupiter), adding a Sagittarius twist to your Aries core.
Aries personality in brief
As a fire cardinal sign ruled by Mars, Aries is bold, energetic, and pioneering — the zodiac’s fearless initiator. That’s the short version — for the full breakdown of Aries traits, strengths and weaknesses, love and compatibility, the Aries man and woman, career, and mythology, read the complete Aries zodiac sign guide.
