lunisolaradj.

Brit.

/ˌluːnᵻˈsəʊlə/,

/ˌljuːnᵻˈsəʊlə/, U.S.

/ˌlunəˈsoʊlər/

Etymology: < Latin lūna moon + solar n.² Compare French lunisolaire.

Astronomy.

Pertaining to the mutual relations of the sun and moon, or resulting from their combined action. lunisolar period n. a cycle of 532 years, that number being the product of 19 and 28, the numbers of years in the cycles of the moon and sun respectively. lunisolar year n. a year whose divisions are regulated by the revolutions of the moon, while its average total length is made to agree with the revolution of the sun. lunisolar precession n. that part of the precession which is caused by the combined attractions of the moon and sun upon the mass of the earth (the remaining effect being due to the attractions of the other planets).
