The International Childrens Day (ICD) is celebrated in numerous countries, usually (but not always) on June 1 each year.每年众多的国家都会庆祝国际儿童节，但常常（不是总是）不是都在6月1日那一天庆祝。
Origin
Origin 起因：The ICD had its origin in the World Conference for the Wellbeingof Children（世界儿童福利大会）in Geneva, Switzerland in 1925. 1925年在瑞士日内瓦召开的关于儿童福利的国际会议上，首次提出了“国际儿童节”的概念。It is not clear as to（关于）why June 1 was chosen as the ICD:one theory has it that the Chinese consul-general总领事 in San Francisco (USA) gathered a number of Chinese orphans to celebrate theDragon Boat Festival（端午节）in 1925, which happened to be on June 1 that year, and also coincided with the conference in Geneva.

June 1 has since been observed as the ICD by numerous countries, especially by Communist countries; in the Western world the ICD is usually celebrated on other days of the year (if at all), and there is often little public awareness about these celebrations. Consequently there is sometimes amisperception（错误观点）that June 1 as the ICD was a Communist invention. Nonetheless, in recent years even some groups within the United States started observing the ICD on June.
