When planning trades, calculating returns, or analyzing market trends, it’s crucial to know the exact number of market days within a given time frame. The Market Days Calculator helps you instantly find the number of trading days between two dates, taking weekends and market holidays into account.

Whether you’re a trader, investor, or financial analyst, this tool saves you time and ensures precision in your market timing and performance calculations.

📘 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.

🪜 How to Use the Market Days Calculator

Enter the Start Date – Choose the beginning of your time period.
Enter the End Date – Select the final date of your analysis.
(Optional) Select a Market/Exchange – For example, NYSE, LSE, or TSX (to apply specific holiday schedules).
Click Calculate – The tool instantly displays:
- Total calendar days
- Total weekends excluded
- Number of market holidays
- Final number of trading days
