For the Qinggong chart or other traditional Chinese calendar calculations, the birth time you need to input is your "true solar time", which is the result of calibrating the local time (clock time) based on the longitude of your place of birth.
Below, I have organized the core logic for you:
The difference between two types of time
Birthplace clock time: This is the time recorded by the hospital or family at the time of your birth, usually the standard time used uniformly in that country or region (such as "Beijing time" in China and "Eastern time" in the United States). It is a man-made regulation for the convenience of daily life, not a strict astronomical time.
China's "True Sun Time": This is an ancient time system that determines the time based on the actual position of the sun in the sky (such as the hour of the hour and the hour of the hour). Due to the roundness of the Earth, the time at which the sun rises and sets varies at different longitudes. Therefore, this system is strongly correlated with location and is truly 'localized' in terms of time.
Simply put, the ancient saying 'at the third quarter of noon, the sun is in the center' refers to the moment when the sun in your location is exactly at the highest point in the south, rather than the 12 o'clock noon displayed on the clock in Beijing or the capital city of your country.
Specific operational steps
Converting your birth time to 'true solar time' only requires two key steps:
Step 1: Find the longitude of your place of birth
You need to know the specific geographic longitude of the city of birth. You can quickly find it through map software or search engines (for example, search for "New York longitude").
Step 2: Calculate and input the time
Enter your birth time (year, month, day, hour) and longitude data into a professional conversion tool or application that supports calibration for "True Solar Time" or "Local Mean Time". These tools will automatically calculate the results you need, and then you can fill in the "birth time" or corresponding "conception time" field of the Qinggong chart with the converted time.
Attention: Special circumstances during daylight saving time
If you were born in a country or region that has implemented or is currently implementing daylight saving time, this is something that needs special attention. If you were born during daylight saving time, you also need to subtract the one hour (usually 1 hour) that was accelerated from the recorded birth time to restore the true "standard time", and then perform the above conversion to true solar time.
