Health Worker's Day, also known as Medical Worker's Day or Healthcare Worker's Day, is observed in Russia, Belarus, Armenia, Kazakhstan, and Moldova on every third Sunday of June. This professional holiday, established in the Soviet Union in 1980, honors health care staff, including doctors, pharmacists, nurses, and other medical professionals, recognizing their vital role in treating and improving human health. Following the collapse of the Soviet Union, several countries continued to celebrate this day, which was re-established by corresponding Presidential Decrees. The day is marked by expressions of gratitude and respect for health workers, highlighting the importance of professionalism, dedication, and compassion in the medical field.
