Calendar Systems - CSV
Calendar systems are frameworks for measuring time and determining dates. There are three main types: solar, lunar, and lunisolar calendars, each using different astronomical phenomena as reference points. Various calendar systems exist rooted in different cultures and religions worldwide, such as the Gregorian, Julian, Hijri, and Chinese calendars, and they continue to be widely used in daily life, religious observances, and agricultural activities.
