How to calculate the time of Great Heat?

The time calculation of the solar terms is based on the position of the Earth on the ecliptic (that is, the orbit of the Earth around the sun). The Great Heat is when the Sun reaches 120° of the ecliptic longitude.
Calculation formula: [Y*D+C]-L
Formula interpretation: Y=last two digits of the year, D=0.2422, L=leap year number, 21st century C=22.83, 20th century=23.65.
For example: The date of the Great Heat in 2088 = [88×0.2422+22.83]-[88/4]=44-22=22, which means the Great Heat is on July 22.
Exception: For the year 1922, add one day to the result.

The Great Heat solar term occurs around the middle of the "dog days" and is known as the hottest period of the year, as well as the period with the highest temperatures in most areas.
