Every stock exchange publishes its own trading calendar. Some are open on days when others are closed, and some close for holidays that do not appear on the public calendar of the country in which they trade. A market may pause for a religious festival, a national holiday, a day of mourning or an exchange-specific closure, and it may also change its trading days when the rules change. An investor who assumes the same calendar everywhere can place orders that wait, or fail to act when they meant to.
This guide explains why trading days differ, what the most common kinds of closure are, how they affect orders and settlement, and where to find the calendar you need. It is general information, not advice on trading.
Why calendars differ
Exchanges set their own calendars. They take account of the national public holidays of their country, but they also choose their own closures for religious or cultural observances, for unusual events and for technical reasons such as system upgrades. A market may close on a day that is a working day in the rest of the country, or stay open on a day that is a public holiday elsewhere.
Trading days also differ from working days. A market can be open on a Saturday in one country, if its rules say so, and closed on Monday in another. Some markets trade on a different set of days from the banks or the government. Assume nothing about the calendar; check it.
The main kinds of closure
National public holidays. Most exchanges close on the main national holidays, often on the same day as the banks.
Religious and cultural observances. Many markets close for major religious festivals. The dates often move from year to year, because they follow lunar or other calendars, so they must be checked each year.
Exchange-specific closures. A market may close for a day for its own reasons, such as a major system change or an event affecting trading.
Shortened or changed sessions. Some markets trade for a shorter session or at different hours on certain days, such as the day before a major holiday, or during a religious period when the trading hours change.
Settlement-only days. On some days the market trades but settlement does not happen, or settlement happens on a different date. This affects when cash and shares actually move.
Why it matters
A closed market cannot take your order or fill it. An order placed for a closed day may wait until the market reopens, or it may expire, depending on how your broker handles it and the validity you chose. If you planned to sell before an event, a closure can delay the sale past the date you needed.
Settlement is affected too. A trade on the last open day before a holiday may settle after the holiday, and a dividend record date may fall on a day the market is closed. Plan for the gap between the trade date and the settlement date, and check both against the calendar.
The guide on stock order types explains how order validity works, which is relevant when a market closes.
A worked example: a sale before a holiday
Suppose you decide on a Thursday to sell a share, and you place a market order that day. The market closes on Friday for a national holiday, and it reopens on Monday. Your order fills on Thursday if the market is open and there are buyers, so the timing is not a problem. But suppose you placed the order on Friday, when the market was closed. The order either waits until Monday or is rejected, depending on your broker.
Now suppose the share goes ex-dividend on the Monday after the holiday, and your trade settles on the Wednesday. Whether you receive the dividend depends on the settlement date relative to the record date. A holiday in the middle of the settlement cycle can move the date on which you are counted as a holder. The example shows why a calendar check is part of planning, not an afterthought.
| Situation | What can happen |
|---|---|
| Order placed on a closed day | Waits, or is rejected, depending on the broker |
| Trade just before a holiday | Settlement may move past the holiday |
| Dividend record date on a closed day | Entitlement depends on the rules of that market |
Where to find the calendar
Each exchange publishes its trading calendar on its own website, usually for the full year. Check it at the start of the year and again if you hear of a change. Your broker may show the closures on its platform, but the exchange's own calendar is the authoritative source. Notices of unscheduled closures and changes to hours are also published by the exchange.
Keep a note of the closures that fall during any period when you plan to trade or need to receive cash. Keep the calendar with your other investment records, so that you can check a date quickly when an order or a payment is due. Set reminders for the days before them, because the last day before a holiday is often when orders and settlements bunch up.
Holidays that move from year to year
Some closures follow dates that change each year, usually because they are set by a lunar calendar or by a decision on the day. The exchange may announce such a closure only a few weeks ahead, and a short notice can leave little time to act on an order you planned. Subscribe to the exchange's notices if you can, and check the calendar again when a new year or a new notice appears. An order placed before an unexpected closure may behave differently from one placed before a scheduled one, so read your broker's rules.
Practical steps
- Check the exchange's own calendar for the full year, not only the next holiday.
- Note the trading days and the settlement days separately.
- Place time-sensitive orders on a day the market is open, and check the order validity.
- Plan the settlement of a sale around a holiday, so that cash is available when you need it.
- Check any record date and dividend date against the calendar.
Common mistakes
Assuming the same holidays everywhere. Each exchange sets its own calendar.
Trusting an old calendar. Religious dates move each year.
Placing an order and forgetting it. Validity settings can carry an order over a closure in ways you did not intend.
Ignoring settlement. A holiday can move the date your cash arrives.
Relying on a broker's summary alone. Check the exchange's own calendar.
Checklist
- Find the exchange's trading calendar for the current year.
- Mark every closure in the period you plan to trade.
- Check the settlement days around each closure.
- Check any record and payment dates for dividends against the calendar.
- Set the validity of time-sensitive orders with a closure in mind.
- Recheck the calendar when the year changes or when a notice is issued.
Key takeaways
Every stock exchange publishes its own trading calendar, which can differ from the country's public holidays and from the calendars of other markets. Closures for holidays, religious observances, exchange-specific reasons and shortened sessions all affect orders and settlement. Plan around the closures, check the settlement and dividend dates against the calendar, and use the exchange's own published calendar as the source of truth.
