Why people check both zodiac systems

Two traditions, one date

The Western zodiac follows your birth month and day, while the Chinese zodiac follows your birth year and the lunar new year — one date gives you both answers.

Boundary dates handled right

Born on March 20 or 21, or in January or February? The calculator uses exact sign start dates and Chinese New Year dates, so cusp birthdays come out right.

Real traits, not horoscopes

Each sign and animal comes with its classic traits and strengths, so you can compare them with your own personality.

Compatibility at a glance

See which Western signs pair best with yours, and which Chinese animals share your compatibility trine.

Element included

Your Chinese animal comes with its element — Wood, Fire, Earth, Metal, or Water — which changes every two years.

Zodiac sign calculator FAQs

What zodiac sign am I if I was born on March 21?
Aries. The Western zodiac runs Aries from March 21 to April 19. March 20 is the last day of Pisces, so a March 21 birthday is the first day of Aries.
What are the Western zodiac sign dates?
Capricorn December 22 – January 19, Aquarius January 20 – February 18, Pisces February 19 – March 20, Aries March 21 – April 19, Taurus April 20 – May 20, Gemini May 21 – June 20, Cancer June 21 – July 22, Leo July 23 – August 22, Virgo August 23 – September 22, Libra September 23 – October 22, Scorpio October 23 – November 21, Sagittarius November 22 – December 21.
Why is my Chinese zodiac animal different from my birth year animal?
Because the Chinese zodiac year starts on Chinese New Year, not January 1. If you were born in January or early February before that year's Chinese New Year, you belong to the previous year's animal. For example, someone born February 9, 2024 is a Rabbit, not a Dragon — the Dragon year began February 10, 2024.
What is my Chinese zodiac element?
Each Chinese zodiac year also carries one of five elements — Wood, Fire, Earth, Metal, or Water — which rotate every two years. 2024 is a Wood Dragon year, 2025 a Wood Snake year, and 2026 a Fire Horse year. This calculator shows your element with your animal.
What is a cusp sign?
A "cusp" birthday falls on the day a sign changes, like March 20–21 or December 21–22. In traditional astrology you still have exactly one sun sign — the sign whose date range contains your birth date. This calculator uses the standard start dates, so cusp birthdays resolve to one sign.
Are Western and Chinese zodiac signs related?
No — they come from separate traditions. The Western zodiac is based on the sun's position at your birth (month and day), while the Chinese zodiac is based on a 12-year animal cycle tied to the lunar calendar (birth year). That is why one person can be, for example, both an Aries and a Dragon.
What does my zodiac sign say about compatibility?
Traditionally, fire signs (Aries, Leo, Sagittarius) pair well together, earth signs (Taurus, Virgo, Capricorn) pair well together, air signs (Gemini, Libra, Aquarius) pair well together, and water signs (Cancer, Scorpio, Pisces) pair well together. In the Chinese system, animals in the same trine — for example Rat, Dragon, and Monkey — are considered most compatible.
