Constitution Day is a major national holiday in Poland observed on May 3rd to commemorate the declaration of the Constitution of 1791, Europe's first modern codified constitution. As a public holiday, government offices, schools, and most private businesses are closed across the country. In the financial markets, the Warsaw Stock Exchange is closed, leading to significantly lower liquidity for the Polish Zloty (PLN) and Polish equities.
This is a fixed-date national holiday and does not involve statistical calculation. It is observed annually on May 3rd regardless of economic cycles.
