Next Business Day Settlement: Which Days Count?

T+1 counts days the settlement system is open. A day the stock market trades can still be a day nothing settles, and that is where the count usually goes wrong.

Short answer

Settlement counts business days when the settlement system is open. Weekends and stock market holidays are skipped, and so are bank holidays such as Columbus Day and Veterans Day, when stocks trade but trades do not settle.

Buy a stock on Friday, October 9, 2026, and it settles on Tuesday, October 13. Saturday and Sunday don’t count, and neither does Monday the 12th, which is Columbus Day: the NYSE and Nasdaq are open that day, but banks are closed and nothing settles. Next-business-day settlement, the T+1 cycle, counts only days the settlement system is open, so it skips weekends, stock market holidays and bank holidays on which the stock market stays open. That last group is the one people miss.

Which days count

A settlement business day is a day the settlement system runs. Weekends, stock market holidays and bank holidays all fall outside it.

Day Stocks trade? Counts toward T+1?
Saturday or Sunday No No
Stock market holiday No No
Bank holiday with the stock market open Yes No
Ordinary weekday Yes Yes

Weekends and exchange holidays are easy. You can’t trade, so you don’t think about them.

Bank holidays are different, because you can trade. Orders fill, positions change and the account looks normal all day. The settlement count just pauses until the banks reopen. Regular-way settlement, the default cycle a trade gets, runs on this calendar. The entry on regular-way settlement covers which securities follow it, from stocks and ETFs to bonds and listed options, and what it takes to settle a trade on any other cycle.

Columbus Day and Veterans Day in 2026

Columbus Day falls on Monday, October 12, 2026. Veterans Day falls on Wednesday, November 11, 2026. On both days the NYSE and Nasdaq are open. The bond market is closed. Banks are closed, and no trade settles.

Look at the pairs. A Friday trade and a Monday trade settle on the same Tuesday, and a Tuesday trade and a Wednesday trade settle on the same Thursday, which means that for a trader watching cash, the holiday adds a day of waiting to the trade before it, while a trade placed on the holiday itself settles as fast as T+1 ever does.

What still happens on a bank holiday

Trading itself carries on. Orders route and fill, quotes move, and every trade made that day carries the holiday as its trade date, so you own shares you bought on Columbus Day from that morning, and you can sell them the same afternoon if you choose, even though the trade behind them has not settled and will not until Tuesday.

What waits is the exchange of cash and securities. Settlement needs the cash to move. With the banks shut, it can’t. Both sides complete together on the next settlement day.

Why the extra day matters

A margin account mostly hides it. A cash account doesn’t.

In a cash account, sale proceeds stay unsettled until the settlement date. Many brokers let you buy with them anyway. The trap is selling that new purchase before the original proceeds settle, which is a good faith violation. Repeat it and the account can be restricted. A bank holiday moves the moment those proceeds settle, and a trader counting one business day on the stock market calendar will get it wrong by a day.

The trader in that example followed the rule as most people state it, one business day after Friday is Monday, and still broke it, because the market was open on Monday and the settlement system was not, so the funds that looked settled were still a day away. Monday looked like any other trading day.

The Veterans Day version works the same way. Sell on Tuesday, November 10, and the money settles Thursday, November 12. That is a day later than the stock market calendar suggests.

Where the count usually slips

Counting on the stock market calendar is the big one, and the Columbus Day example shows where it leads.

Over-correcting is the opposite slip. A trade placed on the holiday itself does not wait an extra day: Monday, October 12 settles Tuesday, October 13, and Wednesday, November 11 settles Thursday, November 12, exactly one settlement day later, the same as any T+1 trade.

Long weekends stack. A Friday trade before a Monday stock market holiday skips Saturday, Sunday and that Monday, and settles Tuesday. When a bank holiday lands on the Monday after a weekend, as Columbus Day does in 2026, all three days drop out of the count in the same way, so the money from a Friday sale stays unsettled through the whole weekend and the holiday, and anyone planning to reuse it on the Monday needs to know that before placing the order.

How to check before you trade

Start with your own confirmation. Every trade confirmation shows a settlement date next to the trade date. On a trade from Friday, October 9, it should read October 13. Planning a sale near a holiday? Look up its settlement date before you spend the proceeds.

For the calendar itself, SIFMA publishes holiday recommendations for the bond market and the exchanges publish their own holiday calendars, and wherever a date shows up as a bond market holiday while the exchanges are open, expect stocks to trade and settlement to wait.

The settlement date calculator counts the days for you. Enter the bank holidays too. Leave them out and the count follows the stock market calendar.

Ordinary weeks are covered in when a stock trade settles under T+1.

The dates shift from year to year, so check the current calendar each time.

Also asked

Can I trade bonds on Columbus Day or Veterans Day?
The bond market is closed on both days in 2026, while the NYSE and Nasdaq are open. Expect stock trading as usual and plan any bond trades for another day.
Does a bank holiday matter in a margin account?
Much less. In a margin account the broker lends against the position, so buying power rarely waits on settlement. The settlement date on the confirmation still moves the same way.
Will a bank holiday also delay a withdrawal to my bank?
It can, because the transfer has to reach a bank that is closed that day. Check your broker's transfer schedule around the holiday before you count on the money.
