Questions

How do I convert a solar date to a Chinese lunar date?

Pick the date in the first form and press the button. You get the lunar month and day, the zodiac year and the solar term if the day has one.

How do I find the solar date of my lunar birthday?

Use the second form: pick the lunar year, month and day. For a birthday in a leap month, choose “Yes, leap month”. The result also lists the same lunar date for the next 10 years.

Which time zone are the lunar dates in?

China Standard Time (UTC+8), the zone the Chinese calendar is calculated in. A new moon close to midnight can put a lunar month start one day off elsewhere.

What is a leap month?

About every three years the lunar calendar adds a thirteenth month so it stays in step with the seasons. It repeats the number of the month before it.

When does the Chinese zodiac year start?

On this site the zodiac year starts at the Start of Spring solar term in early February. It does not start on January 1 or on Chinese New Year. Many people go by Chinese New Year instead, so your zodiac animal may differ depending on which rule you follow.

Why is my zodiac animal different on different sites?

Sites use different start points for the zodiac year. This site uses the Start of Spring solar term in early February, while many people use Chinese New Year. If your birthday falls between those two dates, the two methods can give different animals.

Is there a Chinese calendar converter that handles leap months?

Yes, the second form here does. It converts a lunar date to a solar date and has a leap-month option you can switch on. The first form goes the other way, from a solar date to a lunar one.

Does this converter go in both directions?

Yes, there are 2 forms. One turns a solar date into a lunar date. The other turns a lunar date into a solar date, with a choice for leap months.
