Stock Market Holidays Planner - Organize Market Closures & Half Days
A personal planning template to organize the markets you follow, the closure and half-day dates you expect, your preparation tasks, and notes. It is a research draft you fill in yourself — not a live official market-holiday database, data feed, or advice.
Not financial advice. This calculator is for research and educational purposes only. Outputs are estimates based on the inputs you provide and are not buy or sell recommendations. Always do your own research and consult a licensed professional before making investment decisions.
You can plan up to 6 market holidays at a time.

What it is
A stock market holidays planner is a simple template for organizing the market closures and half-day sessions you want to track. You list the markets you follow, write in the holiday dates you expect, mark the session type and your preparation status, and keep short notes. Everything you see here is entered by you and stays in your browser. It is not a live holiday calendar, it does not pull data from any exchange, and it does not provide investment advice.

Inputs and outputs
Inputs
- Market / exchange
- Pick a real exchange — NYSE, NASDAQ, HKEX, LSE, TSE, SSE, SZSE — or enter a custom market name.
- Holiday date
- A date you fill in yourself — your own expectation, not an official calendar.
- Session type
- Closed, half day, or unknown — your own note for planning.
- Preparation status
- Not reviewed, planned, or done, to track your own progress.
- Notes
- Free text for what you want to prepare for that market.
Outputs
- Upcoming holidays
- Your entries sorted by the dates you filled in, with undated ones grouped separately and half days flagged.
- Market preparation checklist
- Each market shown with its current preparation status.
- Status summary
- A simple count of not reviewed, planned, and done.
- Planning note
- A neutral reminder about your plan — not a recommendation.
Example workflow
- Pick the first exchange you follow, for example NYSE or HKEX.
- Fill in the holiday date you expect, and set the session type to closed or half day.
- Set the preparation status to "Planned" and jot a short note.
- Add a few more markets the same way, up to six.
- Read the upcoming holidays, checklist, and status summary to see your plan at a glance.
The exchange names are real, but every date is something you typed in. Treat this as a personal planning draft and confirm any closure with the exchange’s official calendar.
Common mistakes
- Assuming every market shares the same holiday schedule — closures and half days differ from one exchange to another.
- Writing in a date as if it were official; your expectation can be wrong, so confirm with the source.
- Ignoring half-day sessions, which can shift trading hours even when the market is technically open.
- Cramming too many markets in and never actually completing the preparation.
- Assuming this tool stores your plan — it lives only in your browser session.
When the market takes a holiday, value does not
In July 1914, as the First World War broke out, the New York Stock Exchange did something unimaginable: it closed — and stayed closed for about four months, the longest shutdown in its history. Yet the railroads kept running, the factories kept producing, and the businesses behind the unquotable stocks kept earning. When trading resumed, ownership had lost nothing but a price feed.
Buffett turned this into his sharpest test: only buy a stock you would be happy to own if the market closed for ten years. A holiday calendar is useful for logistics — settlement dates, order timing, earnings weeks. It is also a reminder with each closed day: the quote is a convenience, not the asset.
Use market holidays to plan your trading logistics — and to remember that a business's value never depends on the exchange being open.
The watchlist that traded while he slept
John Templeton kept a permanent list of companies he admired but refused to buy at prevailing prices — each with a written-down price at which it would become a bargain. Then he went further: he left standing buy orders with his brokers at those prices, so that when a panic arrived, the buying happened automatically, before his own emotions could interfere.
He explained the logic plainly: in a crash, even disciplined investors freeze. The list and the pre-set orders were decisions made by his calm self on behalf of his future frightened self. Many of his best entries — including amid the 1987 crash — were executed by orders placed months earlier.
A watchlist is half a decision. Attach a target price to every name — decided in calm — and the panic does the rest of the work for you.

Frequently asked questions
Does this show real market holidays?
No. This planner does not connect to any data source and does not display official market holidays. Every date is one you type in yourself as your own expectation, so always confirm closures with each exchange’s official calendar.
Is a market holiday a buy or sell signal?
No. A market holiday is simply a day the market is closed or trades a shorter session. It is not a signal to trade, and this tool does not provide buy, sell, or hold recommendations.
Can I use real exchange names?
Yes. The market selector includes NYSE, NASDAQ, HKEX, LSE, TSE, SSE, and SZSE, and you can also type a custom market name. The exchange names are real labels for your plan — the holiday dates remain your own entries, not official data.
Is my plan saved?
No. Everything stays in your current browser session and is not stored or sent anywhere. If you refresh the page, the plan resets.
Will this connect to live data later?
The tool is built data-ready, so a future version could show a real data source and last-updated time. For now it runs in manual mode and every entry is your own.
