What National Day Is Today?
Look up which "National Day" calendar-tradition observance (if any) falls on today's date.
Covers commonly observed US calendar-tradition days (Pi Day, Star Wars Day, National Coffee Day, and similar) - informal calendar traditions, not an exhaustive or official registry, and not government holidays.
Key features
- Checks today's date against a curated list of about 35 widely-recognized US "National Day" observances and shows the match, if any, the moment the page loads.
- When no listed observance falls on today's date, shows a clear "no listed national day for today" message instead of guessing.
- Renders the full curated list of all 35 national days, sorted by calendar date, as a plain HTML table below the result.
- Computes the date from your device's own clock with no upload, no account, and no network request.
How it works
The check runs fresh from your device's own clock every time the page loads, so come back tomorrow and it reflects the new date automatically - there is nothing to refresh or update by hand.
Privacy and data handling
Everything computes locally in the browser from a curated static dataset. Nothing is uploaded, no account is needed, and the page makes no network request of any kind.

Examples across the year
This national day checker's curated list spans the full calendar, not just the three examples named above. Other entries include Groundhog Day (February 2), Earth Day (April 22), Juneteenth (June 19), National Dog Day (August 26), Halloween (October 31), Human Rights Day (December 10), and New Year's Eve (December 31) - about 36 dates in total, each tied to a fixed month and day rather than a moving rule. Because only about 36 of the year's 365 days have a curated match, most days show the "no listed national day for today" message instead of a result - that gap is expected behavior, not a bug in the check.
National day vs. public holiday
This tool's national-day checker and its holiday-countdown mode answer two different questions, and only one of them is active on this page.
| Mode | Basis | Where it lives |
|---|---|---|
| National day (this page) | Informal calendar tradition (Pi Day, Star Wars Day, National Coffee Day, and similar) - no legal status | The curated list on this page, shown above |
| Holiday countdown (separate mode) | Government-recognized public holiday for the US, Canada, the UK, or Australia | A different mode of this same tool, with its own country selector and per-holiday countdown - not shown on this page |
The two modes also differ in how their dates are computed. Every entry in this page's national-day list is a fixed month and day, so matching today's date is a simple equality check. The holiday-countdown mode instead has to handle rules like "the last Monday in May" (Memorial Day) or "the fourth Thursday in November" (Thanksgiving), which take more than a fixed date to compute - this national-day checker never needs that extra step, because none of its curated entries move around the calendar.
Frequently Asked Questions
What does this tool show?
It checks today's date against a curated list of commonly observed US "National Day" calendar traditions (Pi Day, Star Wars Day, National Coffee Day, and similar) and shows a match on load, plus the full list sorted by date.
Are these official government holidays?
No. These are informal calendar-tradition days, not government-recognized public holidays.
Is this a complete list of every "National Day"?
No - this is a curated list of commonly observed days, not an exhaustive or official registry. Some regional or niche observances may be missing.
Does the list change from year to year?
No. Each entry uses a fixed calendar month and day - for example, National Pi Day is always March 14 - so the same dates repeat every year; only the day of the week each one falls on shifts.
Does this tool track or remember what I look up?
No. Nothing about your visit is stored beyond the current page session, and nothing is sent to any analytics or tracking service.
