Flag Day in Brazil is observed every November 19, commemorating the adoption of the national flag in 1889 following the proclamation of the Republic. Although it is not a public holiday, special ceremonies take place, including the singing of the Brazilian Flag Anthem. The current flag, which replaced the imperial flag, was designed to symbolize national unity during the transition from a monarchy to a republic. The flag features a green field, which is believed to represent forests; a yellow diamond, symbolizing the country's riches; a blue globe with stars representing the sky and Brazilian rivers; and 27 stars that denote the Brazilian states and the Federal District. The flag was modified in 1992 to add six stars, reflecting the creation of new states. While there is no official meaning for the flag's colors, popular interpretations exist that connect them to Brazil's natural and cultural heritage.
