What is the purpose of holiday calendars in financial markets?

The purpose of holiday calendars in financial markets is to coincide with market closes and reflect national and religious holidays. This is essential because financial markets often close or have altered trading hours during holidays, which can significantly impact trading volumes, liquidity, and overall market activity. By understanding when these holidays occur, traders and investors can make informed decisions regarding their trading strategies, adjust their positions accordingly, and be aware of periods of potential volatility or reduced market activity.

While seasonal trends in consumer behavior, historical market data for analysis, and corporate earnings announcements are all important aspects of financial markets, they do not directly relate to the function of holiday calendars. Holiday calendars specifically address the operational considerations tied to market functioning during recognized holidays.
