Commonwealth Day is celebrated annually on the second Monday in March. It is a day to recognize the unity and shared values of the Commonwealth of Nations, a political association of 54 member countries, many of which were formerly part of the British Empire. The day promotes understanding, cooperation, and friendship among member nations. Each year, Commonwealth Day has a specific theme that highlights important issues affecting the global community. Celebrations often include educational activities, cultural events, and community service projects, encouraging people to engage with the values of democracy, peace, and development that the Commonwealth stands for.
