National Mourning is a period of grief observed by a country in response to the death of a significant figure or a tragic event. This practice often includes flags being flown at half-mast, public memorial services, and moments of silence. It serves to honor the memory of those lost and to provide a collective space for citizens to express their sorrow. During National Mourning, various institutions, including schools, government buildings, and businesses, may close or alter their operations to reflect the somber mood. The duration and specific customs associated with National Mourning can vary by country and situation, depending on cultural practices and the impact of the loss.
