Why know market holidays?
The stock market isn't always open just because it's a weekday. On each country's public holidays, the exchange is closed and no trading takes place. On these days, order execution, deposits and withdrawals, and settlement are pushed back — so checking ahead when planning trades or money transfers helps you avoid unnecessary hiccups.
Public holidays vs. market closures
This calendar is based on each country's 'public holidays.' But public holidays and actual market closures don't always match. US markets, for example, have 'half-days' such as the day after Thanksgiving when they close earlier than usual, which won't show up in holiday data. Conversely, an exchange's own closure days may differ from public holidays. So use this calendar as a reference, and confirm dates that matter for trading against the relevant exchange's official notices.
How is the data provided?
Holiday information is pulled from the Nager.Date service, which provides open data. If the data can't be loaded temporarily, a built-in list of major public holidays is shown instead for reference. If you revisit the same day, saved information is reused for faster loading.
