Recurrence pattern: every year in August.

Republic Day is observed in Chad every November 28, commemorating the day in 1958 when Chad became an autonomous state within the French Community. The holiday marks the culmination of a decolonization process that began during World War II, following years of ineffective French governance since the colonial era began in 1891. On this day, both Christians and Muslims come together to celebrate Chad's proclamation as a free republic. Traditional customs include enjoying football matches, which are a popular activity on this national holiday. The significance of Republic Day lies in its representation of Chad's journey towards independence, which was fully achieved on August 11, 1960.
