The civil version of the Julian calendar is based on the su, and so it is solar. However, the Julian calendar includes an undated lunar calendar that allows it to calculate when Easter is, so it is lunisolar.
The Chinese calendar aligns perfectly with the cycle of the moon. It is a lunisolar calendar that incorporates both lunar and solar movements to track time.
Julius Caesar replaced the lunar Roman calendar with the solar Julian calendar in 46 BCE. It took effect beginning in 45 BCE.
Although the Gregorian calendar has "months", it is not in any way governed by the phases of the moon. It is strictly a solar calendar, so its emphasis is to remain in sync with the solstices and equinoxes, the characteristics of the Earth's orbit of the sun. Only lunar calendars, like the Muslim calendar, and lunisolar calendars, like the Jewish calendar, are based on the phases of the moon, with each month beginning at the time of the new moon.
The lunar calendar is based on the phases of the Moon, with each month typically consisting of 29 or 30 days. It begins with the new moon and tracks the Moon's cycle through its phases, resulting in a year of about 354 days, which is shorter than the solar year of 365 days. Various cultures have their own versions of lunar calendars, such as the Islamic calendar, which is purely lunar, and the Chinese calendar, which is lunisolar, incorporating both lunar months and solar years. These calendars often feature festivals and observances aligned with specific lunar phases.
Some countries that use the lunar calendar include Saudi Arabia, Israel, China, South Korea, and Indonesia. The Islamic calendar is based on lunar cycles, while countries like China and Korea use a lunisolar calendar which incorporates both the lunar and solar cycles.
It is lunisolar. It is based on the solar year, with adjustments to keep the months in line with the lunar cycle.

The Gregorian Calendar is solar and the Hebrew Calendar is lunisolar.
Lunar calendar
The Chinese calendar is lunisolar calendar when compared to the Islamic calendar which is a purely lunar calendar. A lunisolar calendar means that the months are determined by 29-30 day lunar cycles, but the years are designed to remain relatively consistent with the 365-366 day solar years. This is in contrast to purely solar calendars (like the popular Gregorian calendar), whose months have no correlation with the lunar cycles, or purely lunar calendars (like the Islamic calendar), whose years are 354 days, allowing the months to move around the solar year.As a result, the Chinese New Year will always fall between late January and early March, but the Islamic holiday of Eid ul-Fitr circles the year every 33 years. (i.e. It moves earlier and earlier by 11 or 12 days each year, which results in it returning to roughly the same position every 33 solar years.)Of course, in addition to the distinction between lunisolar vs. lunar, there are also different start dates and different holidays.
August 25, 1972, corresponds to the 15th day of the 7th month in the Year of the Rat in the Chinese lunisolar calendar. This date falls during the traditional Ghost Festival, a time when families honor their ancestors. The lunisolar calendar is based on both lunar phases and the solar year, aligning the months with the moon's cycles while ensuring the seasons remain consistent.
The Muslim calendar is based on the lunar calendar and it does not have any leap years. The Lunar calendar is shorter than the Solar calendar and therefore the Muslim calendar falls out at a different point in the Solar calendar every year.
