A lunisolar calendar is a calendar system that combines both lunar and solar cycles to determine the passage of time, often aligning months with moon phases while adjusting to the solar year. This ensures that the calendar remains in sync with seasonal changes, making it useful for agricultural and religious purposes in various cultures.

A calendar system is a way to organize days and months so we know when things happen, like birthdays or holidays. It helps us keep track of time and plan for the future.

Lunar cycles describe the regular pattern of changes in the Moon's illumination as seen from Earth, driven primarily by its orbit around Earth as both orbit the Sun. These phases, from new moon to full moon and back, affect various biological and ecological systems as well as cultural and human activities throughout time.

The passage of time is a fundamental aspect of human experience, shaping perceptions of reality and influencing emotions, memories, and decision-making processes. Understanding time's passage involves examining its subjective nature, as people often experience it differently based on psychological states, contexts, and cultural backgrounds.

A solar year, also known as a tropical year, is the time it takes for the Earth to complete one orbit around the Sun, measured relative to the equinoxes, averaging about 365.242 days. This period is fundamental to the Gregorian calendar, which is designed to align with the solar year to ensure seasonal consistency over long periods.

Seasonal changes refer to the cyclical transformations in climate and environment that occur throughout the year due to the Earth's axial tilt and orbit around the Sun. These changes significantly impact ecosystems, agricultural cycles, and human activities by altering temperature, daylight, and weather patterns.
