Overview: Understanding Trading Days in a Year
If you invest in stocks, trade forex, or simply follow the financial markets, you may have wondered: Exactly how many trading days are there in a year?
It’s not just a random curiosity. The number of trading days impacts your strategies, your returns, and even the way you time your moves in the market.
A trading day refers to any day the stock exchange is open for buying and selling. However, not every weekday is a trading day. Weekends, national holidays, and occasional special closures cut down the total number of active days.
In the United States, both the New York Stock Exchange (NYSE) and NASDAQ typically operate for about 252 trading days per year. This figure can change slightly because of leap years or rare schedule changes.
Knowing this number helps traders organize their plans, measure performance accurately, and prepare for opportunities or risks. Let’s explore exactly how this is calculated, why it matters, and how trading days differ across the world.
How Many Trading Days Are There in a Year in the US?
In the US, the stock market averages 252 trading days each year. This is based on the total days in the year minus weekends and official market holidays.
Here’s the breakdown:
- Total days in a year: 365 (or 366 in leap years)
- Weekend days: 104 (52 weeks × 2 days: Saturday & Sunday)
- Market holidays: Around 9 to 10 per year
- Special closures: Occasionally due to emergencies or national events
Example calculation:
365 total days – 104 weekend days – 9 market holidays = 252 trading days
This number isn’t fixed. Depending on how holidays fall on the calendar, a year may have 251 or 253 trading days.
Why the Number of Trading Days Matters to Investors
The number of active market days affects several aspects of trading:
- Performance Tracking
If you track your investment returns, knowing how many days the market was open ensures your data is accurate. - Strategy Planning
Some strategies depend on daily, weekly, or monthly patterns. The total number of trading days affects these patterns directly. - Risk Management
Fewer trading days mean less time to respond to changes, which can increase urgency. - Tax Planning
The count of trading days can influence how short-term or long-term capital gains are calculated.
Example: A trader doing a “Day Trading Challenge” must base their results only on actual market days. Ignoring this could lead to incorrect conclusions.
US Stock Market Holidays That Affect Trading Days
The US stock market closes on certain official holidays. The NYSE and NASDAQ follow the same schedule.
| Holiday | Date | Notes |
| New Year’s Day | Jan 1 | Observed on nearest weekday if it falls on weekend |
| Martin Luther King Jr. Day | 3rd Monday in Jan | Federal holiday |
| Presidents Day | 3rd Monday in Feb | Market closed |
| Good Friday | Varies (Mar/Apr) | Friday before Easter |
| Memorial Day | Last Monday in May | Start of summer season |
| Juneteenth | June 19 | Added to schedule in 2021 |
| Independence Day | July 4 | Observed before/after if on weekend |
| Labor Day | 1st Monday in Sept | End of summer |
| Thanksgiving Day | 4th Thursday in Nov | Early close next day |
| Christmas Day | Dec 25 | Observed before/after if on weekend |
If a holiday is on a Saturday, the market closes the Friday before. If it falls on a Sunday, the following Monday is observed.
Half-Day Trading Sessions in the US
Sometimes the US markets close early—usually at 1 p.m. Eastern Time—on special occasions. These are still counted as trading days but have lower trading volumes.
Common half-days include:
- The day after Thanksgiving (Black Friday)
- Christmas Eve (if it’s a weekday)
- Occasionally before Independence Day
Early closures can result in slower market activity and fewer price movements.
Global Comparison: Trading Days in Other Markets
Not all countries follow the US pattern. Trading days differ based on local holidays and customs.
| Country / Market | Average Trading Days | Key Differences |
| USA (NYSE/NASDAQ) | 252 | US-specific holidays |
| UK (London Stock Exchange) | 253 | Closes for UK bank holidays |
| Japan (Tokyo Stock Exchange) | 245 | Includes Golden Week holidays |
| India (NSE/BSE) | 250 | Several religious holidays |
| Australia (ASX) | 253 | Observes Australian national holidays |
The differences mainly come from each country’s holiday calendar and cultural events.
Impact of More or Fewer Trading Days
The number of trading days in a year can influence:
- Market Volatility – Fewer days can lead to higher trading activity per day.
- Investor Behavior – Long breaks can make traders cautious or eager.
- Liquidity – Less time to trade can mean lower yearly trading volumes.
Example: If one year has only 251 days instead of 252, traders may still aim for the same profits, potentially making more aggressive moves.
How to Plan Trades Around Trading Days
- Check the official calendar – Know exactly when markets open or close.
- Adjust deadlines – Especially for options expiry and quarter-end strategies.
- Plan around holidays – Market movement can slow before long weekends.
- Use volatility – Shorter weeks sometimes cause sharper price changes.
