What is the lunar calendar what is the calendar
In daily life, we often hear the terms "lunar calendar" and "calendar", but what is the difference between them? Why are some festivals calculated according to the lunar calendar and others according to the calendar? This article will give you a detailed analysis of the definitions, differences, and application scenarios of the lunar calendar and the calendar.
1. Definition of lunar calendar and calendar
1. Lunar calendar (lunar calendar)
The lunar calendar, also known as the lunar calendar, is a calendar based on the changing phases of the moon. Its main feature is to calculate months based on the moon's waxing and waning cycle (about 29.5 days). The lunar year usually has 12 months, but in order to be consistent with the solar year, a leap month is added every few years, so the length of the lunar year is about 354 or 355 days.
2. Calendar (Gregorian/Gregorian calendar)
The calendar, usually referred to as the Gregorian calendar, is a calendar based on the movement of the Earth around the Sun. Its main feature is to calculate the year based on the length of the solar year (approximately 365.25 days). The Gregorian calendar has a fixed year of 365 days, a leap year has 366 days, and the number of days in the month is also relatively fixed.
