lunisolar calendar
Also known as lunar calendar with corrections to match it to the length of the solar year
calendar based on the solar time of the tropical year with months related to the regular cycle of the Moon's phases
AI overview
A lunisolar calendar combines the Sun's yearly cycle with the Moon's monthly phases, so it tracks both solar seasons and lunar months at the same time. This matters because it allows calendars to stay aligned with seasonal changes in nature while also following the Moon's visible cycle, which many cultures find important for religious observances and daily life.

Record of the Chinese calendar for 1834, 1835, and 1836 during the Qing dynasty under the Daoguang Emperor's Reign (道光十四年，道光十五年，道光十六年)
A lunisolar calendar is a calendar that combines monthly lunar cycles with the solar year. As with all calendars which divide the year into months, there is an additional requirement that the year have a whole number of months (Moon cycles). The majority of years have twelve months but every second or third year is an embolismic year, which adds a thirteenth intercalary, embolismic, or leap month.
