Lunar New Year 2023: What to know about the Year of the Rabbit

Sunday, Jan. 22 marks the start of the Lunar New Year, one of the biggest celebrations in the world to usher in the arrival of spring.

More than a billion people worldwide will celebrate the Year of the Rabbit — as each year is named after one of twelve Chinese zodiac signs. Last year was the Year of the Tiger.

In China, where it’s known as the Spring Festival, Lunar New Year is the most important time of the year for family gatherings. It’s also celebrated in South Korea, Vietnam, Thailand, Mongolia and other Asian countries.

Here’s everything you need to know about the two-week-long festival.

When is Lunar New Year?

Lunar New Year begins with the second new moon after the winter solstice, so it starts on a different day each year. It marks the beginning of the lunisolar calendar. According to the University of California Irvine, Lunar New Year in 2023 starts on Jan. 22 and culminates on Feb. 5 with the Lantern Festival.

The Chinese government expected over 2.1 billion journeys to be made during a 40-day travel period from Jan. 1 through early February.

What are the origins of the Lunar New Year?

How the Lunar New Year came to be is still "somewhat obscure," researchers say.

One possibility is that it started some 3,500 years ago as animal worship in northern nomadic tribes, according to UC Irvine.

In Buddhist lore, animals rushed to say farewell to a dying Buddha. Chinese folklore says it started as a contest among the animals when the Jade Emperor was picking palace guards.

"In either version, the ox was to be the first to arrive, but the rat cheated by riding on the ox’s back and made a last-minute dash to the finish line," UC Irvine professor Hu Ying says.

In Vietnam, Lunar New Year is known as Tết, while it’s called Seollal in Korea. In the U.S., it’s often called Chinese New Year.

What is the Year of the Rabbit?

The rabbit is one of 12 Chinese zodiac signs the Lunar New Year follows. This year is known as the Year of the Rabbit. Hu Ying, a professor of East Asian studies at UC Irvine, says the rabbit is a sign of "longevity, peace and prosperity."

"People born in a year of the Rabbit are believed to be vigilant, witty, quick-minded, and ingenious," Ying says.

"It’s a year of hope," Law says.
