The short answer: years, not Western-style months
Chinese zodiac signs months
This search usually mixes two systems. The familiar Chinese animal is based on the lunar birth year; Aries, Taurus, and the Western signs are organized by month and day.

Direct answer
Are Chinese zodiac signs based on months?
No—the popular Rat-to-Pig sign is a year animal. It changes at Lunar New Year, not at the beginning of a Gregorian month. A birth month matters in a full Four Pillars chart, but it does not replace the well-known birth-year animal.

Why the search phrase exists
Understanding “Chinese zodiac signs months”
English speakers often meet Western astrology first, so “zodiac sign” suggests a month-and-day lookup. Applying that expectation to Chinese astrology produces searches for Chinese zodiac signs months or dates. The terminology overlaps, but the familiar calculations do not.
To find the popular Chinese sign, enter the complete birthday and identify the Chinese lunar year containing that date. Month and day are still necessary because Lunar New Year falls between late January and mid-February. They help resolve the year boundary; they do not assign one animal to January, another to February, and so forth.
Does Chinese astrology have month animals?
Yes, but that is a different layer. Four Pillars of Destiny constructs a year, month, day, and hour pillar, and every pillar has a Heavenly Stem and Earthly Branch. The month branches begin around solar terms rather than the first day of each Gregorian month.
Tiger corresponds to the first traditional solar month beginning near the Start of Spring, followed by Rabbit, Dragon, Snake, Horse, Goat, Monkey, Rooster, Dog, Pig, Rat, and Ox. These month branches describe a chart component; they are not what most people mean when asking “What is my Chinese zodiac sign?”
Common confusion resolved
“Chinese zodiac signs dates” usually asks for Lunar New Year boundaries.
“Chinese zodiac signs months” may ask about Western-style sign dates or
the specialist Four Pillars month branch. The intended answer depends on
which system the searcher means.
How to find the sign you probably want
Use the Chinese zodiac calculator for the birth-year animal and element. The calculator requires month and day only to check whether the birthday came before or after Lunar New Year. It then returns Rat through Pig, the year element, Yin or Yang polarity, and exact date range.
If you want Aries through Pisces, use a Western sun-sign calculator. If you want a Four Pillars chart, you need birth date, time, and often location plus a clearly stated calendar convention. Keeping those tasks separate prevents this guide from giving a confident answer to the wrong question or mixing distinct traditions.
