March 30

National Doctors' Day was first observed in 1933 in Winder, Georgia, to recognize the contributions of physicians to patient care. In 1990, the U.S. Congress designated March 30 as National Doctors' Day to be celebrated annually. The date was chosen to commemorate the first use of general anesthesia in surgery by Dr. Crawford Long in 1842. On this day, patients and communities show appreciation through cards, gifts, and special events at hospitals and clinics. Hospitals often hold ceremonies, host recognition awards, and share stories highlighting doctors' achievements. The observance fosters public awareness of the role physicians play in advancing medical science and promoting public health.

The School Day of Non-violence and Peace (DENIP) was initiated by poet Llorenç Vidal in 1964 to foster a culture of peace through education. Observed annually on March 30, it encourages schools to organize activities such as readings, art projects, and discussions centered on non-violence. Students learn about conflict resolution, human rights, and environmental responsibility. The day often includes silent assemblies, peace circles, and exhibitions of student artwork conveying messages of harmony. Although rooted in Spain, DENIP has inspired similar initiatives worldwide. UNESCO has recognized its impact, and many international schools participate in collaborative peace-building projects on this day.
