The short answer is: The Chinese calendar primarily uses China Standard Time (CST), which is UTC+8.
Here’s a more detailed explanation to ensure you adjust correctly for your local time.
The Official Time Zone: China Standard Time (UTC+8)
For all official purposes, including the calculation of public holidays and the beginning of lunar months, the People's Republic of China uses a single time zone: China Standard Time (CST) or Beijing Time.
This means:
The Chinese New Year, for example, begins at midnight (00:00) CST on the first day of the first lunar month.
A new lunar month begins at the time of the astronomical new moon, calculated for the UTC+8 time zone.
Why This Matters for You
If you are trying to determine the exact start of a day in the Chinese calendar (like the start of Chinese New Year, the Mid-Autumn Festival, etc.), you must convert from UTC+8 to your own local time zone.
Example: Chinese New Year's Day 2024 (Year of the Dragon)
It officially began on February 10, 2024, in the CST time zone.
If you were on U.S. East Coast Time (EST, UTC-5), which is 13 hours behind CST, the new year actually began for you on the evening of February 9, 2024.
So, you don't "adjust" the calendar itself; you convert the date and time from Beijing Time to your local time.
A Note on Historical and Cultural Context
While the modern standard is clear, it's worth knowing that historically, the Chinese calendar was calculated locally. Before the adoption of a single national time zone in 1949, different regions would base their calendars on their own local solar time (e.g., Beijing Solar Time, Nanjing Solar Time). However, for any contemporary use, UTC+8 is the definitive standard.
How to Be Sure for Your Location
For Major Holidays: The simplest method is to look up "Chinese New Year 2025 [Your City]" or use a world clock website. It will automatically do the conversion for you.
For Precise Lunar Phases: If you are calculating something based on the exact moment of the new moon (which defines the first day of the month), you would find the astronomical data for that event in UTC, and then:
Convert UTC to CST (UTC+8) to get the official calendar date in China.
Then, convert that CST time to your local time zone.
In summary: To ensure you are correct, always perform your time conversions from China Standard Time (UTC+8).
