What festival is February 29th?

February 29th, up to August 30th, 20 19, represents three festivals, namely, female courtship day, international rare disease day and world living condition survey day.

1 and February 29th are traditional "women's courtship days" in Europe. As early as 1288, Scotland passed a law to designate February 29th as "Women's Rights Day". At that time, Queen Margaret issued a decree announcing that on February 29th of leap year, women could propose to men, and fined men who freely pursued women and refused to accept warnings.

February 29th is the International Day for Rare Diseases. One day in these four years means that rare diseases with an incidence of one in ten thousand or even one in one million are extremely rare. "International Day for Rare Diseases" aims to raise public and government awareness of rare diseases and the problems faced by rare disease groups. Rare diseases refer to rare diseases with low prevalence rate, which are generally chronic and serious, often life-threatening.

3. The World Living Condition Survey Day was founded in 2003, and the United Nations specialized agencies designated the last day of February as the World Living Condition Survey Day every year, aiming at urging governments and societies to pay more attention to people's living environment and conditions, and to solve some problems for society through various activities.

The particularity of February 29th:

1, February 29th is the 60th day of leap year in Gregorian calendar, and there are 306 days before the end of the year. February 29th does not appear in normal years, but only in leap years. Usually, a leap year is a year that can be divisible by 4. However, it is not entirely accurate for the actual celestial bodies to run every four years. Therefore, if the year is defined as a multiple of 100, it must be divisible by 400 to become a leap year. For example, 2000 is a leap year, but 1900 is not.

February 29th is a very special day. This is a day that human beings make up every four years to make up for a little more than 365 days a year. The julian calendar formulated by the ancient Romans in 46 BC did this for the first time. At present, the method of setting leap in Gregorian calendar is to leap every four years, but not every hundred years, such as 2 100 and 2200, but every 400 years.
