Year and month lookup
What is my Chinese zodiac sign? Look it up by birth year and month
Most people remember the year and the month they were born, not the day. That is enough for eleven months out of twelve — and for the twelfth, the honest answer is that the day decides.

This month sits entirely on one side of the line, so the month adds nothing here — the year decides, and the answer above is the whole answer.
This page uses Li Chun. The lunar-new-year line falls on a different date in the same month, and both are listed year by year in the year-boundaries dataset linked below.
Why one month is ambiguous and the other eleven are not
The year pillar does not change on 1 January. It changes at Li Chun, which falls on 3, 4 or 5 February in all 200 years the dataset covers, so January always belongs to the previous year pillar and March onward always belongs to the current one. Only February can hold both, and only February needs a day.
A birth on the turning day itself cannot be settled from a date alone: the year pillar changes at an instant, and the hour decides which side of it a birth falls on. This lookup does not take an hour, so it does not pretend to answer that case.
