Ngày 25/2 âm lịch năm 2023 là ngày mấy dương lịch?
The lunar calendar, also known as the lunisolar calendar, is a calendar system that is based on the cycles of the moon. It is used in many cultures around the world, including China, Vietnam, and Korea. The lunar calendar is different from the Gregorian calendar, which is the most widely used calendar system in the world. The Gregorian calendar is based on the solar year, which is the time it takes for the Earth to orbit the sun.
Understanding the Lunar Calendar
The lunar calendar is based on the cycles of the moon. A lunar month is the time it takes for the moon to complete one cycle of phases, from new moon to full moon and back again. A lunar month is approximately 29.5 days long. The lunar calendar year is made up of 12 lunar months, which is approximately 354 days long. This is shorter than the solar year, which is approximately 365.25 days long.
The Difference Between Lunar and Gregorian Calendars
The difference between the lunar and Gregorian calendars is that the lunar calendar is based on the moon's cycles, while the Gregorian calendar is based on the sun's cycles. This means that the lunar calendar year is shorter than the Gregorian calendar year. To make up for this difference, the lunar calendar adds an extra month to the year every few years. This extra month is called a leap month.
