日历

The Chinese word 日历 (rìlì) for "calendar" is a compound of two characters: 日 (rì), meaning "sun", and 历 (lì), meaning "to calculate" or "to record". The original meaning of 日历 was therefore "a record of the days", and it was used to refer to a variety of different types of calendars, including solar calendars, lunar calendars, and lunisolar calendars.Over time, the meaning of 日历 has narrowed to refer specifically to a solar calendar, which is a calendar that is based on the Earth's orbit around the sun. Solar calendars are the most common type of calendar in use today, and they are used in most countries around the world.The Chinese calendar is a lunisolar calendar, which means that it is based on both the Earth's orbit around the sun and the moon's orbit around the Earth. The Chinese calendar is one of the oldest calendars in the world, and it has been used in China for over 4,000 years.
