* **Holidays:** The number of stock market holidays can fluctuate slightly year to year.
* **Weekends:** Since weekends aren't trading days, the specific placement of weekends within a year can cause a one-day difference.
For a specific year, you can consult a resource like a stock exchange calendar to determine the exact number of trading days.
