lunisolar
A lunisolar calendar marks the seasons by the sun and the months by the moon.
- Adjective:
- Relating to or dependent upon both the moon and the sun: Describes phenomena, cycles, or systems that are influenced by or calculated from the positions and motions of both the moon and the sun.
- Pertaining to the mutual relations of the moon and sun: Refers to the combined gravitational or astronomical effects of these two celestial bodies.
- Adjective:
- The lunisolar calendar is used to determine the dates of many religious holidays.
- Tides are a classic example of a lunisolar phenomenon, influenced by both the moon and the sun.
"Lunisolar precession": A slow gyration of Earth's axis, resulting from the combined gravitational pulls of the sun and moon on Earth's equatorial bulge.
- Lunisolar precession is a key component in the long-term change of star positions.
"Lunisolar cycle": A period, such as the Metonic cycle, which synchronizes lunar months with the solar year.
- The ancient Greeks used a lunisolar cycle to improve their calendar.
Lunisolar calendar (n): A calendar whose date indicates both the moon phase and the time of the solar year.
- The Hebrew calendar is a well-known lunisolar calendar.
Lunisolar theory (n): An explanation or model based on the combined influence of the moon and sun.
- The lunisolar theory of tides was developed by Isaac Newton.
- Selenoheliacal (adj): A technical synonym meaning pertaining to both the moon and sun. (Note: This term is very rare.)
- Moon-sun (adj): A simple descriptive compound (often used attributively, e.g., moon-sun alignment).
Lunisolar gravitational perturbation: A disturbance in an orbit caused by the combined gravity of the sun and moon.
- Satellite orbits require corrections for lunisolar gravitational perturbations.
Lunisolar interval: A time measurement related to the positions of both bodies.
- The lunisolar interval is critical in some ancient astronomical calculations.
A lunisolar calendar marks the seasons by the sun and the months by the moon.
- relating to or attributed to the moon and the sun or their mutual relations
