The number of active trading days per year varies based on a number of factors. The number matters because the number of trading days per year is used in volatility modeling, option pricing, and other quantitative financial metrics.
252 is the median number of trading days per year in U.S. markets from 2010 to 2022. But that is not the number every year.
Why the Number of Trading Days per Year Changes
The number of trading days per year varies based on how holidays align with weekends, but also major events can cause the markets to close. Past major events include:
- U.S. markets closed for 4 days following the terrorist attacks on September 11, 2001
- Markets were closed for 2 days in 2012 following Hurricane Sandy
- In 2018, markets were closed December 5 after former president George H.W. Bush died
