📘 What Is a Market Day?
A market day refers to any business day when financial markets (such as stock exchanges) are open for trading. Typically, this means Monday through Friday, excluding weekends and official market holidays.
For example:
- Stock markets like the NYSE or NASDAQ are open ~252 trading days per year.
- Forex markets operate 24/5 globally.
- Crypto markets trade 24/7 (no market days distinction).
The Market Days Calculator helps you easily determine the total trading days in any date range — perfect for calculating returns, annualized rates, or trade durations.
🧮 Formula & Calculation Logic
The calculator uses the following logic: Market Days=Total Days−Weekends−Market Holidays\text{Market Days} = \text{Total Days} – \text{Weekends} – \text{Market Holidays}Market Days=Total Days−Weekends−Market Holidays
If holidays are provided (based on your selected market), those are subtracted as well.
