International Children's Day is one of the oldest international holidays. The decision to hold it was taken in 1925 at the World Conference on the Welfare of Children in Geneva. History is silent why it was decided to celebrate this children's holiday on June 1.
According to one version, in 1925, the Consul General of China in San Francisco gathered a group of Chinese orphans and arranged for them a celebration (Dragon Boat Festival), the date of which just fell on June 1st. Luckily, the day coincided with the time of the “children's” conference in Geneva.

After the Second World War, when the problems of preserving the health and well-being of children were more urgent than ever, in 1949 a congress of women was held in Paris, at which an oath was made to fight tirelessly for lasting peace, as the only guarantee of the happiness of children. In the same year, at the Moscow session of the Council of the Women's International Democratic Federation, in accordance with the decisions of its 2nd Congress, today's holiday was established. And a year later, in 1950, on June 1, the first International Children's Day was held, after which this holiday is held annually.
International Children's Day has a flag. On a green background, symbolizing growth, harmony, freshness and fertility, stylized figures are placed around the sign of the Earth - red, yellow, blue, white and black. These human figures symbolize diversity and tolerance. The sign of the Earth, placed in the center, is a symbol of our common home.
Interestingly, this holiday was actively supported in countries that have chosen the socialist path of development. In the era of the existence of the Soviet Union, on June 1, summer holidays began in schools. International Children's Day was celebrated with speeches and discussions about children's rights and well-being, screenings of new children's feature films and TV shows, sports competitions for children, often inviting parents to participate. And today in many countries on this day there are many mass, entertainment and cultural events for children.
But Children's Day is not only a fun holiday for the children themselves, it is also a reminder to society of the need to protect the rights of the child, so that all children grow up happy, study, do what they love and become wonderful parents and citizens of their country in the future.
