Aries Dates at a Glance

When Does Aries Season Start and End?

Aries season starts on March 21 and ends on April 19. It begins when the Sun enters Aries, which happens at the spring (March) equinox, and it ends when the Sun moves into Taurus the next day, April 20.

Some sites list the dates a day earlier or later. That isn’t an error. The Sun changes signs at a specific moment rather than 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 most people, March 21 to April 19 is the right range.

Aries Season Start Date by Year

Times are in UTC. In time zones ahead of UTC, the date can roll over to March 21. The standard Aries dates (March 21 – April 19) are the ones used for everyday horoscope sun signs.

Is My Birthday Aries? Check Your Date

So, is March 26 Aries? Yes. Is April 17 Aries? Yes. Every date from March 21 through April 19 is Aries.

Aries Cusp Dates

A cusp is the changeover point between two signs. Aries has two:

• Pisces–Aries cusp (around March 17 – 23): the end of the zodiac year meets the start of the next one.
• Aries–Taurus cusp (around April 16 – 22): the first sign hands over to the second.

Astrologically, you belong to one sign or the other, not both. For a boundary birthday, the only way to know for certain is to check the exact moment the Sun changed signs in your birth year, since the cutoff can fall before or after your birth time.

Aries Decan Dates

Each sign is split into three decans of about ten days. These are the Aries decan dates:

• First decan: March 21 – March 30 (ruled by Mars)
• Second decan: March 31 – April 9 (ruled by the Sun)
• Third decan: April 10 – April 19 (ruled by Jupiter)
