Market holidays and hours

In short

I once stood outside a locked door on a Monday morning, certain I had somewhere to be, and learned the hard way that the day was a holiday. You have probably felt something close to that when you tried to place a trade and nothing happened. U.S. stock markets close on certain holidays, and the exchanges publish the full list each year. The regular trading day runs from 9:30 a.m. to 4:00 p.m. Eastern time, with early closing on a few days. A friend of mine keeps the exchange calendar pinned on her fridge, and it saves her a good deal of grief. Check the calendar before you plan a trade, a transfer, or a deadline. Doing so costs you nothing.

The whole of it

What it is

A neighbor of mine ran a hardware store for forty years, and he kept hours you could set a clock by. The stock market works much the same way. It opens at a set time, closes at a set time, and takes certain days off.

If you are holding shares, or thinking about buying some, you share the market's schedule whether you like it or not. The big exchanges, the New York Stock Exchange and Nasdaq, publish their trading hours and holiday closures on their own websites. Those pages are the source of truth.

The regular session runs from 9:30 a.m. to 4:00 p.m. Eastern time. That is the stretch when most trading takes place and when prices get set in full view of everyone. Outside those hours, some brokers offer what is called extended hours trading. That means buying and selling before the opening bell or after the closing bell. It works a bit differently, and I will say more about that below.

How it works

I once watched a young man in a coffee shop get frustrated because his order sat there all evening and never went through. He had placed it at nine at night. Nobody had told him that an order placed after the close usually waits for the next session.

Here is the plain version. When the market is open, a buy or sell order can be matched with someone on the other side. When it is closed, your broker holds your order until trading starts again. The order does not vanish. It simply waits its turn.

Extended hours trading is a side door. Many brokers let you place orders before 9:30 a.m. or after 4:00 p.m. Eastern. Fewer people are trading then. That can mean wider gaps between the price a buyer offers and the price a seller wants. It can also mean prices that jump around more. Each broker sets its own extended hours rules, so read yours.

The market also closes early on a few days. Those early closes are usually at 1:00 p.m. Eastern. The exchanges list which days get that treatment each year.

Then there is the matter of settlement. When you sell a stock, the money does not land in your account the same instant. The Securities and Exchange Commission has moved the standard settlement cycle for most securities to one business day after the trade, a rule known as T plus 1. Only business days count. A weekend or a market holiday does not count as a business day. So a sale made just before a holiday weekend can take longer to settle than you might expect.

The numbers, and where to find yours

You have probably wondered which days exactly the market takes off. The exact dates shift from year to year, because holidays like Memorial Day and Labor Day fall on different calendar dates. So I will not guess at them here.

The NYSE publishes its holiday and early close schedule on its website, under its holidays and trading hours page. Nasdaq publishes its own on its website too. The two follow very nearly the same calendar, but check the one that matches where your investment trades.

The regular session is 9:30 a.m. to 4:00 p.m. Eastern time. Early close days end at 1:00 p.m. Eastern. For the dates this year, look to the official exchange calendar, which the site will show here as the current figure, which the official source publishes each year.

Your broker's page matters too. It will tell you its own extended hours window and when it cuts off orders for the day. Those cutoffs can sit a little earlier than the exchange's, so look them up.

A worked example

A woman I will call Dolores had a long weekend coming. She decided on a Thursday to sell some shares and use the money for a home repair due the following Tuesday. The Monday of that weekend was a market holiday.

Let us walk through her calendar. She placed her sell order on Thursday morning, during the regular session, and it filled that day. Under a one business day settlement cycle, the sale would settle one business day later.

Now count the business days. Thursday is the trade day. Friday is one business day later, so settlement lands on Friday. No holiday gets in the way yet, so the cash settles on Friday.

Suppose instead Dolores had waited until Friday afternoon to sell. Friday is the trade day. The next business day is not Saturday or Sunday, and it is not the holiday Monday. It is Tuesday. So the sale made Friday would settle on Tuesday.

The inputs here are simple. A Friday trade, plus one business day, with Saturday, Sunday, and the Monday holiday skipped, gives Tuesday. Her repair bill was due that very Tuesday, so cutting it that close would have been a real squeeze. Selling on Thursday gave her breathing room. Dolores was glad she counted.

Where it goes wrong

I once knew a fellow who trusted his phone to tell him when the market was open and learned it was wrong on a holiday. A few common slips catch honest people, and none of them mean you are careless.

The first slip is assuming the market is open because it is a weekday. A weekday holiday closes the exchanges even though banks and shops in your town may be running. Always check the official calendar.

The second is forgetting time zones. The market runs on Eastern time. If you live in Denver or Los Angeles, 4:00 p.m. Eastern arrives sooner than you think. A trade you meant to make after work may land after the bell.

The third is mixing up the market's holiday with the bank's. Some days the stock market is shut while banks are open, and some days it is the other way around. If you are moving money between a bank and a brokerage, a day off on either side can slow things down.

The fourth is trading in extended hours without knowing the risks. Thin trading can mean a price that looks fine and then moves against you. Read your broker's notes before you try it.

The last slip is setting a deadline on a holiday or the day after one. If you need cash by a certain date, count backward in business days, and leave yourself a cushion.

Questions to answer before you leave this page

Have you looked at the official exchange calendar for this year, and do you know which weekdays the market takes off? Do you know what time the regular session closes in your own time zone, and not just in New York? Does your broker offer extended hours trading, and have you read its rules and its cutoff times? If you plan to sell shares to pay a bill, have you counted the business days it takes for the cash to settle, skipping weekends and holidays? Is there a deadline on your calendar that falls near a holiday, and have you given yourself a day or two of room? And if you are ever unsure, have you checked the NYSE or Nasdaq website, or your broker, instead of trusting a guess?
