How Many Trading Days in a Year? 251 in 2026 (NYSE)

Most articles will tell you there are 252 trading days in a year. The New York Stock Exchange publishes 251 for 2026, 251 for 2027, and 251 for 2028, and 2025 actually finished with 250. Here is the real count, month by month, straight off the exchange’s own calendar.

Key Takeaways

The US stock market has 251 trading days in 2026: 249 full sessions plus two half days.
The NYSE publishes 251 trading days for 2027 and 2028 as well. The familiar 252 is a long-run average used for annualizing math, not a calendar fact.
The count moves when a holiday shifts weekdays, when a leap year adds a Monday-to-Friday day, or when the exchange closes unexpectedly, as it did on January 9, 2025.

How Many Trading Days Are in a Year?

The short answer for the United States is 251 in 2026.

That number comes from the New York Stock Exchange, which publishes an estimated trading-day table for US cash equities and US equity options several years ahead. It lists 251 days for 2026, 251 for 2027, and 251 for 2028.

The arithmetic is simple enough to check yourself. 2026 has 365 calendar days. It opens on a Thursday, which works out to 52 Saturdays and 52 Sundays, so 104 weekend days come off the top and leave 261 weekdays. The NYSE closes for ten holidays in 2026. 261 minus 10 is 251.

Two of those 251 sessions are half days, so if you are counting full sessions the number is 249. Both figures matter depending on what you are calculating, and I cover the half days further down.

Year	Q1	Q2	Q3	Q4	Total trading days
2026	61	62	64	64	251
2027	60	63	64	64	251
2028	63	62	63	63	251

Those are NYSE estimates for US cash equities. Nasdaq keeps the same holiday schedule, so the count is identical for Nasdaq-listed stocks.

Trading Days by Month in 2026

Monthly counts swing from 19 to 22 depending on how the weekends and holidays fall. February is reliably among the thinnest months, and March, July, October, and December carry the most sessions in 2026.

Month	2026 trading days	2027 trading days
January	20	19
February	19	19
March	22	22
April	21	22
May	20	20
June	21	21
July	22	21
August	21	22
September	21	21
October	22	21
November	20	21
December	22	22
Total	251	251

If you are working out a monthly profit target or a monthly risk budget, 21 is the number to plan around. It is the average in both years, and nothing shows up more often.

When the US Stock Market Is Closed in 2026

The NYSE closes for ten holidays in 2026. Juneteenth National Independence Day has been a full market closure since 2022, and it is the one most calendars still leave out.

Holiday	2026 date
New Year’s Day	Thursday, January 1
Martin Luther King Jr. Day	Monday, January 19
Washington’s Birthday (Presidents’ Day)	Monday, February 16
Good Friday	Friday, April 3
Memorial Day	Monday, May 25
Juneteenth National Independence Day	Friday, June 19
Independence Day (observed)	Friday, July 3
Labor Day	Monday, September 7
Thanksgiving Day	Thursday, November 26
Christmas Day	Friday, December 25

Independence Day falls on a Saturday in 2026, so the market observes it on Friday July 3 and closes for the full day rather than running the usual July 3 half session.

Good Friday is the closure that surprises people, because it is not a federal holiday. Banks and government offices are open; the stock market is not.

Half Days: When the Market Closes Early

Two of the 251 sessions in 2026 end at 1:00 p.m. Eastern instead of 4:00 p.m. Eligible options run fifteen minutes longer and close at 1:15 p.m.

Friday, November 27, 2026, the day after Thanksgiving
Thursday, December 24, 2026, Christmas Eve

A half day still counts as a trading day. It just gives you three and a half hours of the regular session instead of six and a half. Volume on these days is usually thin and spreads widen, which is worth knowing before you size a position into one of them. If you trade intraday, our breakdown of the best time frame for intraday trading is a useful companion here, because the compressed session changes what a normal bar looks like.

Why the Number Changes From Year to Year

Four things move the count.

Where the weekends fall. A 365-day year holds 52 full weeks plus one spare day, and a leap year holds two spares. When those spare days land on a Saturday or Sunday you get 105 or 106 weekend days instead of 104, and the weekday total drops.

Which weekday a holiday lands on. This is the big one. When a fixed-date holiday like Independence Day or Christmas falls on a Saturday or Sunday, the market either observes it on the adjacent weekday or skips the closure entirely. In 2028, New Year’s Day falls on a Saturday and the NYSE observes no New Year’s holiday at all.

Leap years. 2028 adds February 29, but because it lands on a Tuesday it adds a trading day rather than a weekend day. The total still comes to 251 because the holiday calendar absorbs the difference.

Unscheduled closures. These do not show up on any published calendar. The market closed on Thursday January 9, 2025 for the national day of mourning for former President Jimmy Carter, which turned a scheduled 251-day year into an actual 250-day year. It closed for four straight sessions after the September 11 attacks in 2001 and for two days during Hurricane Sandy in 2012. The published number is a schedule, not a promise.

Why Traders Still Use 252

If the real count is 251, why do the finance textbooks use 252?

Because 252 is the long-run average, and averages are what annualizing math needs. Run the counts back over the last several decades and they cluster between 250 and 253, with 252 sitting in the middle. Once that number went into the standard volatility formula it stayed there.

The place you meet it most often is annualized volatility. Daily volatility gets scaled to an annual figure by multiplying by the square root of 252, roughly 15.87. Options pricing models, backtest engines, and risk platforms almost all use 252 as the default, which means your broker’s implied volatility figure and your backtest results are both built on that assumption.

The practical takeaway: use the NYSE count when you are planning a calendar and use 252 when you are running annualizing math. Swapping one for the other in a volatility calculation moves the result by well under a percent, so it is not worth agonizing over. Just know which one you are holding.

What 251 Trading Days Means for Your Trading Plan

The count stops being trivia the moment you attach a number to it.

Per-day expectancy. If you want to make $25,000 in a year, that is roughly $100 per trading day across 251 sessions, or about $481 a week if you only trade one session per week. Dividing an annual goal by 251 instead of 365 usually reveals that the goal was more aggressive than it looked.

Sample size. A strategy that produces one setup a week gets 52 attempts a year. At one a day it gets 251. If you are trying to work out whether an edge is real or you are looking at noise, the number of trading days is the ceiling on how much evidence you can gather. That is the honest argument for tracking every trade rather than the memorable ones: over my years of trading the trades I remembered clearly were never a representative sample of the trades I actually took.

Risk budget. Traders who cap themselves at a fixed percentage of account risk per day are implicitly setting an annual risk budget of that number times 251. Seeing the annual figure written out tends to change how people size.

Compounding. A 0.5% average daily return compounds very differently over 251 sessions than the same figure applied to 365 days. Run your own numbers through our compound interest calculator using 251 periods rather than 365, and check position sizing against the risk reward calculator before you commit to a per-day target.

One more angle worth knowing: a small handful of those 251 sessions carry most of the year’s return. Our look at the best days in stock market history shows how concentrated the gains are, which is the standard argument against sitting in cash waiting for a cleaner entry.

Trading Days vs Calendar Days vs Business Days

Three counts get confused constantly, and settlement dates are where it bites.

Calendar days: all 365. Interest accrues on calendar days.
Business days: weekdays minus federal holidays, roughly 250 in 2026. Banks use this.
Trading days: weekdays minus exchange holidays, exactly 251 in 2026.

Business days and trading days are close but not identical, because the exchange calendar and the federal calendar disagree in both directions. Good Friday closes the market but not the banks. Columbus Day and Veterans Day close the banks and the bond market but not the stock market. If you are counting toward a settlement date, use the calendar that belongs to the instrument you are holding.

How to Count Trading Days Yourself

You do not need a data feed for this.

Start with the calendar days in the year, 365 or 366 in a leap year.
Subtract the weekend days, normally 104.
Subtract the exchange holidays that fall on a weekday, ten in 2026.
Check the result against the NYSE trading-day table.

If you want to verify a past year rather than a future one, pull the daily price history for a broad index or ETF from any free data source, filter to the year you want, and count the rows. Every row is one session the market was open, which catches unscheduled closures that no published calendar shows. Comparing the row count to the scheduled count is how you spot years like 2025.

A related date question that trips people up is options expiration, since expiration Fridays cluster volume and volatility in ways an ordinary session does not. Our guide to what OPEX means in stocks covers which of the 251 days those are and why they behave differently.

FAQ

How many trading days are in a year?

In the United States, 251 in 2026. The NYSE publishes 251 for 2027 and 2028 as well. The count has historically run between 250 and 253 depending on where holidays and weekends fall, which is why 252 is quoted as the long-run average.

How many trading days are left in 2026?

Count the remaining sessions from the monthly table above. Full-year 2026 is 251, and the quarterly split is 61 in Q1, 62 in Q2, 64 in Q3, and 64 in Q4, so anyone checking mid-year can subtract the quarters already completed and then add the remaining months.

How many trading days are in a month?

Between 19 and 22, with 21 as the typical month. February is consistently the shortest at 19 sessions and the 22-day months in 2026 are March, July, October, and December.

Why do traders use 252 trading days instead of the actual count?

Because 252 is the long-run average and annualizing formulas need a fixed constant. Daily volatility is scaled to an annual figure using the square root of 252, and options pricing models and backtest engines default to the same number. Use the exchange’s published count for calendar planning and 252 for annualizing math.

Is the stock market closed on Juneteenth?

Yes. Juneteenth National Independence Day has been a full NYSE and Nasdaq closure since 2022. In 2026 it falls on Friday, June 19.

What are the half days in 2026?

Two: Friday, November 27 (the day after Thanksgiving) and Thursday, December 24 (Christmas Eve). Both close at 1:00 p.m. Eastern, with eligible options running until 1:15 p.m. Both still count as trading days.
