Lunar 5/26

Why a lunar birthday moves every year

The Chinese lunar calendar tracks the phases of the moon, so a fixed lunar date — a birthday on, say, the 15th of the 8th month — lands on a different Gregorian day every year. Leap months, added roughly every three years to keep the lunar year aligned with the seasons, shift it further, which is why the same birthday can move by several weeks. MoonCal handles all of this for you when it builds a calendar subscription.

Lunar birthday & calendar converter FAQ

What is a Chinese lunar calendar converter?: A Chinese lunar calendar converter turns a Gregorian (solar) date into its Chinese lunar date, or the other way round. It also works as a lunar birthday calculator: enter a lunar birthday and it shows the Gregorian date for this year and the years ahead, along with the zodiac animal, the ganzhi year and any solar term or festival on that day.
How do I convert a Gregorian date to a Chinese lunar date?: Choose “Gregorian → Lunar”, pick the date and convert. You’ll get the lunar year, month and day — including whether it falls in a leap month — along with the zodiac animal and ganzhi year.
How do I convert a lunar birthday to a Gregorian date?: Switch to “Lunar → Gregorian” and enter the lunar year, month and day of the birthday. Because a lunar birthday lands on a different Gregorian date each year, convert the specific year you need — or subscribe with MoonCal to get the next 20 years at once.
Why does a lunar birthday fall on a different date every year?: The lunar calendar follows the phases of the moon, so a fixed lunar date drifts across the Gregorian calendar from year to year. Leap months shift it further, which is why the same birthday can move by several weeks.
Can Google Calendar remind me of a lunar birthday every year?: Not on its own — a yearly-repeating Google Calendar event keeps the same Gregorian date and drifts away from the real lunar birthday. MoonCal fixes this by generating a subscription that puts the correct Gregorian date into Google Calendar, Apple Calendar and Outlook every year.

Your Chinese zodiac sign depends on the lunar year of your birth — and if you were born in January or February, it may belong to the previous year.
