International Missing Children's Day is celebrated on May 25, the same day as the United States' National Missing Children's Day designated by Ronald Reagan in 1983.
The Global Missing Children’s Network (GMCN) was Launched in 1998 as a joint venture of the International Centre for Missing & Exploited Children (ICMEC) and the US's National Centre for Missing & Exploited Children (NCMEC).
Every year on May 25, GMCN members pay respects to International Missing Children’s Day.
