Why is there 365 days in a normal year and 366 days in a leap year
Because the earth we live on always revolves around the sun. It takes 365 days, 5:48:46 seconds for the earth to revolve around the sun. For convenience, we set a year as 365 days, which is called an ordinary year. In this way, there is almost one more day every four years. If we add this day to February, there will be 366 days in this year, which is called a leap year. In ancient China, we know that there are 365 days and 1 / 4 in a year
