Quick answer: The U.S. stock market has 251 full trading days in 2026, plus 2 half-day (early-close) sessions — November 27 (the day after Thanksgiving) and December 24 (Christmas Eve). The NYSE and Nasdaq are closed for 10 federal holidays, all weekends, and observe early closes at 1:00 p.m. ET on those two half-days.

The Math: How 251 Is Calculated
The number of trading days in a year is not a fixed constant. It depends on (1) how many weekend days fall in the year, (2) how many holidays fall on weekdays (versus weekends, which add no extra closures), and (3) whether any unscheduled closures occur.
| Calculation Step | 2026 Value |
|---|---|
| Total calendar days | 365 |
| Saturdays + Sundays in 2026 | −104 |
| Weekdays subtotal | 261 |
| Federal market holidays on weekdays | −10 |
| Full trading days | 251 |
| Early close (half-day) sessions | +2 |
| Total sessions with any trading | 253 |
The two early-close days — November 27 (the day after Thanksgiving) and December 24 (Christmas Eve) — are partial sessions that end at 1:00 p.m. ET for equities and options, with the bond market closing at 2:00 p.m. ET. They still count as trading days; they are just shorter.
The 10 NYSE & Nasdaq Holidays in 2026
All 10 federal market holidays in 2026 fall on weekdays, so each removes a trading day from the calendar. If a holiday had fallen on a Saturday or Sunday, it would have been observed on the closest weekday — but that does not add a closure; it shifts one. In years with weekend-falling holidays, the trading-day count can differ.
- New Year’s Day — Thursday, January 1, 2026
- Martin Luther King Jr. Day — Monday, January 19, 2026
- Washington’s Birthday (Presidents’ Day) — Monday, February 16, 2026
- Good Friday — Friday, April 3, 2026
- Memorial Day — Monday, May 25, 2026
- Juneteenth — Friday, June 19, 2026
- Independence Day (observed) — Friday, July 3, 2026 (July 4 falls on Saturday)
- Labor Day — Monday, September 7, 2026
- Thanksgiving Day — Thursday, November 26, 2026
- Christmas Day — Friday, December 25, 2026
Trading Days Per Month, 2026
If you are running monthly performance attribution, position-sizing rules, or DCA schedules, here is the per-month count.
| Month | Full Trading Days | Early-Close Days | Closures |
|---|---|---|---|
| January | 20 | 0 | Jan 1 (NYD), Jan 19 (MLK) |
| February | 19 | 0 | Feb 16 (Presidents’) |
| March | 22 | 0 | — |
| April | 21 | 0 | Apr 3 (Good Friday) |
| May | 20 | 0 | May 25 (Memorial) |
| June | 21 | 0 | Jun 19 (Juneteenth) |
| July | 22 | 0 | Jul 3 (Independence observed) |
| August | 21 | 0 | — |
| September | 21 | 0 | Sep 7 (Labor) |
| October | 22 | 0 | — |
| November | 19 | 1 | Nov 26 (Thanksgiving), Nov 27 (½) |
| December | 22 | 1 | Dec 24 (½), Dec 25 (Christmas) |
| Year Total | 250+1=251 | 2 | 10 full closures |
(Note: month totals can vary by ±1 depending on how end-of-month weeks split. The annual sum of 251 is the figure that matters for annualization.)
Why the Number of Trading Days Matters
The “trading days in a year” question seems trivial, but it shows up in real calculations:
Annualized volatility. Daily standard deviation is converted to annualized form by multiplying by the square root of the number of trading days. The classic shortcut is √252; for 2026 specifically it is √251. The difference is small but real for high-precision risk models.
Dollar-cost averaging. A daily DCA strategy in 2026 would execute 251 buys (plus 2 half-day buys if your broker triggers on those). A weekly strategy that always executes Wednesday would execute 52 times unless a Wednesday lands on a closure.
Options expiration math. Days-to-expiration calendars (calendar days vs. business days) for options pricing models (Black-Scholes, binomial) depend on this count. Most retail options sites quote calendar days; institutional desks more often use trading-day counts.
Backtesting. Strategy backtests that use daily bars should account for the actual number of bars per year. Comparing a 2024 backtest to 2026 forward results requires consistent trading-day handling.

Bond Market vs. Stock Market: Different Day Counts
The U.S. bond market follows the SIFMA recommended schedule and closes on additional days that the stock market remains open:
- Columbus Day / Indigenous Peoples’ Day (Monday, October 12, 2026) — bond market closed; stock market open.
- Veterans Day (Wednesday, November 11, 2026) — bond market closed; stock market open.
- Good Friday — bond market open for an early-close 12:00 p.m. ET session; stock market closed.
SIFMA also recommends early closes (2:00 p.m. ET) for fixed income on the trading days before major holidays: May 22 (before Memorial Day), July 2 (before Independence Day), November 27, December 24, and December 31.
Trading Days Over Recent Years
For context, here is the trading-day count for recent and upcoming years:
| Year | Full Trading Days | Notes |
|---|---|---|
| 2023 | 250 | Good Friday off; 10 holidays |
| 2024 | 252 | Juneteenth Wed; July 4 Thu; leap year |
| 2025 | 252 | 10 holidays; standard year |
| 2026 | 251 | Independence Day observed Fri Jul 3 (Jul 4 = Sat) |
| 2027 | 250 | Christmas observed Fri Dec 24 (Dec 25 = Sat) |
The variance comes from how holidays fall on the calendar. When a holiday lands on Saturday or Sunday, the observed weekday closure shifts to Friday or Monday, but does not add or remove from the total weekday count beyond the underlying weekday/weekend distribution of the year.
Frequently Asked Questions
How many trading days are in 2026?
251 full trading days plus 2 early-close (half-day) sessions, for a total of 253 days with any trading activity.
Is the trading-day count always 252?
No. 252 is the typical figure used in textbooks and volatility formulas as a convention. The actual count for any given year is 250, 251, 252, or 253 depending on the calendar.
What is an early-close day?
A day when the NYSE and Nasdaq close at 1:00 p.m. ET instead of 4:00 p.m. ET. Equity options also close early. The bond market typically closes at 2:00 p.m. ET on those days. In 2026, there are two: November 27 and December 24.
Are early-close days counted as trading days?
Yes. They are partial sessions, but stocks still trade and settle. Most data providers include them in their trading-day counts.
Does the bond market have the same number of trading days as the stock market?
No. The bond market is closed on additional days (Columbus Day, Veterans Day) and open on Good Friday, so the bond-market trading-day count differs slightly each year.
