Have you ever wondered how many trading days there are in a year and why it even matters? If you’ve ever dabbled in the stock market or thought about investing, you might have realized how important a tiny detail like this can be. Many people get puzzled because they’re not sure how many trading days are packed into a calendar year, especially since it varies from the usual 365. Knowing exactly how many trading days are in a year can help you plan your investments better and avoid missing out on crucial opportunities. In this post, you’ll discover the magic number and why it’s such a vital piece of information for traders. With experience in the market, I’ll break it down so you can understand how it all works.
What Are Trading Days?
A trading day is any day when the stock market is open for buying and selling. This differs from calendar days, as trading days do not include weekends or public holidays. Understanding the number of trading days is important for investors and traders because it helps them plan and evaluate potential returns on their assets.
How Many Trading Days Are There in a Year?
In the US stock market, such as the New York Stock Exchange and Nasdaq, there are approximately 252 trading days each year.
How the 252 Trading Days Are Calculated
- Annual calendar has 365 days (366 in a leap year).
- Subtracting 104 weekend days.
- Subtracting 9-10 market holidays.
For instance, in a recent calendar year, we saw 252 trading days, but in some leap years, there can be 253.
| Year | Trading Days |
|---|---|
| 2021 | 252 |
| 2020 | 253 |
| 2019 | 252 |
Why 252 Trading Days?
The 252-day trading schedule is designed to maximize market liquidity while considering the well-being of market participants. Scheduled holidays and strategic market closures add up to this specific number.
What Determines the Trading Schedule?
The NYSE and Nasdaq set the trading calendar, taking into account public holidays and ensuring optimal efficiency.

Frequently Asked Questions (FAQ)
How is a trading day different from a business day?
A trading day is when a stock exchange is open for buying and selling securities. A business day is a standard working day—typically Monday through Friday excluding public holidays—and may include days when markets or banks are closed.
Do global markets follow the same calendar?
No. Each exchange follows its own local schedule—weekends, public holidays, and workweek norms vary around the world (e.g. Saudi Arabia trades Sunday–Thursday, others Monday–Friday).
Can the number of trading days change “unexpectedly”?
Yes. Unplanned events—like emergencies, national disasters, or regulatory interruptions—can lead to sudden market closures, impacting the annual total of trading days.
Tips and Tools for Tracking Trading Days
As someone who closely follows market schedules, I recommend setting up alerts through reliable financial apps. Downloadable calendars and real-time resources can help traders plan around market events and holidays.
