The Chinese Calendar and the New Year

Understanding that one thing sorts out most of the confusion in Chinese astrology, so this page is about the calendar before it is about anything else.

Two calendars at once

The Chinese calendar is really two calendars running side by side.

The first follows the Moon. A month begins on the day of the new moon and runs until the next one, about twenty nine and a half days later, and twelve of those months make a year of about 354 days. That is eleven days short of the Sun's year, so every two or three years an extra month is slipped in to keep the Moon's year and the seasons from drifting apart. This is the calendar that sets the festivals, and it is the one that sets New Year.

The second follows the Sun. The year is divided into twenty four solar terms, each about fifteen days long, marking the Sun's progress round the sky. Start of Spring, about 4 February, is the first of them. These dates barely move from one year to the next, the way our 21 June solstice barely moves. This is the calendar the farmers used, and it is the one that sets the month animals.

Western astrology, as it happens, is built on the same solar divisions. The twelve signs are twelve slices of the Sun's year, which is why Aries always begins about 21 March. The two traditions part company over the Moon's calendar, which the West never used for its zodiac.

Why New Year moves

New Year falls on the second new moon after the December solstice. The solstice is fixed, about 21 or 22 December, but the new moons fall where they fall, so the second one after it can land anywhere from 21 January to 20 February. That is the whole mystery.

Here are the recent ones. 2024 began on 10 February. 2025 began on 29 January. 2026 began on 17 February. 2027 begins on 6 February. The dates look random and are anything but. They are simply the Moon.

The January and February trap

This is where people get their animal wrong, and I see it often enough to give it its own section.

If you were born between 1 January and about 20 February, your Western year and your Chinese year may be different years. The Chinese year that carries your animal did not start until New Year, so a birthday before New Year belongs to the previous animal, and to the previous element as well.

Two examples. Someone born on 10 February 2026 was born a week before the Fire Horse year began on 17 February, so they are a Wood Snake, the animal of 2025. Someone born on 25 January 1992 was born before the New Year of 4 February 1992, so they are a Metal Goat from 1991, and the Water Monkey they were told about at school was never theirs.

It goes the other way too. New Year in 1966 fell on 21 January, so anyone born on 25 January 1966 is a Fire Horse even though the month had barely started. If your birthday is in January or the first three weeks of February, look up the New Year for your year before you read your animal's page. The Animals pages each give the recent years with this caveat for exactly that reason.

Why the months follow the Sun

Here is the part that surprises people who have got as far as the year. The year animal follows the Moon and begins at New Year. The month animal follows the Sun and begins at the solar terms. Two different clocks in the same system.

The reason is practical. The lunar months drift about, and the leap month would leave one animal with two months every few years, which is no use for describing a person. The solar terms stay put. So the Tiger month begins at Start of Spring, about 4 February, and the eleven months after it follow at roughly the same dates every year, give or take a day. The Twelve Months page lists all twelve.

It also means the Chinese solar year begins about 4 February, which can be as much as a fortnight either side of the lunar New Year. In the years when New Year falls after 4 February, you can be for a few days in the new year's month animal and the old year's year animal at once. The system does not mind. The Ox month, from about 6 January to 3 February, is the last month of the year even though it sits in January, because the year's months start with the Tiger.

The sixty year cycle

Twelve animals give you the cycle everyone knows. Five elements, Wood, Fire, Earth, Metal and Water, each one yang in one year and yin in the next, make a cycle of ten. Run twelve and ten together and they only come back to the start after sixty years. That is the full Chinese cycle, and in the old reckoning a sixtieth birthday was a return to the year you were born in.

The year's element comes from the last digit of the Western year, and it is worth memorising. 0 and 1 are Metal, 2 and 3 Water, 4 and 5 Wood, 6 and 7 Fire, 8 and 9 Earth. Even digits are yang years and odd digits yin. The Five Elements and Yin and Yang pages take each of those further.

Where the names come from

Put the two together and you have the year's name. 2026 ends in 6, which is Fire and yang, and 2026 is a Horse year, so it is the year of the Fire Horse. 2025 ended in 5, Wood and yin, and was a Snake year, so it was the Wood Snake. 2027 ends in 7, Fire and yin, and is a Goat year, so the Fire Goat is on its way.

Each name only comes round once in sixty years. The last Fire Horse year was 1966, and the next will be 2086. If you were born in 1966, 2026 is your year coming back.

The Fire Horse year

2026 is the year of the Fire Horse. It began on 17 February 2026 and runs to 5 February 2027, when the Fire Goat takes over. Anyone born between those dates is a Fire Horse. Anyone born on 1 January 2026, or any day up to 16 February, is a Wood Snake.

Those dates are the same wherever you are in the world for this purpose. New Year is a calendar date, so the pages here never need a clock.

I wrote about the mood of this year in The Year of the Fire Horse post when the Horse month arrived in June, and the monthly posts take each month animal as it comes. The Week Ahead every Monday carries the Chinese line for all twelve animals. This page is the fixed reference underneath them.
