Fixed national days that land on a weekend in 2027
Of the 170 national days on this calendar, 50 fall on a Saturday or Sunday in 2027. Workplaces and schools that celebrate them will need to pick a nearby weekday.
- National Pi Day: Sunday, March 14
- National Siblings Day: Saturday, April 10
- National Daughters Day: Saturday, September 25
- National Boyfriend Day: Sunday, October 3

Who creates national days, and which are official?
Anyone can start a national day, and most come from companies, nonprofits, or fans. Of the 170 days on this calendar, 30 are set by federal law, 5 are proclaimed by the President, 2 come from a congressional resolution, and 133 are unofficial.
| Status | What it means | Days on this calendar |
|---|---|---|
| Federal law | Congress names the day in law, usually in Title 36 of the U.S. Code | 30 |
| Presidential proclamation | The President proclaims the day, often every year | 5 |
| Congressional resolution | The House, the Senate, or both pass a resolution in support | 2 |
| Unofficial | A person, company, or group starts the day and promotes it | 133 |
National days set by federal law
Chapter 1 of Title 36 of the U.S. Code lists the patriotic and national observances that Congress has named. They include Mother’s Day, Father’s Day, National Grandparents Day, Flag Day, and the National Day of Prayer. Most of these laws ask the President to issue a proclamation each year. None of them give workers a day off.
National days proclaimed by the President
Some days rest on a presidential proclamation rather than a standing law. Armed Forces Day, Military Spouse Appreciation Day, and Bill of Rights Day are proclaimed most years. National Ice Cream Day began with a proclamation by President Ronald Reagan in 1984.
Unofficial national days
Most national days have no government status. A company, charity, or individual picks a date and promotes it. Registries such as National Day Calendar review proposals and decide which days to list.
Some unofficial days are decades old. The Salvation Army in Chicago started National Donut Day in 1938. Patricia Bays Haroski registered Boss’s Day with the U.S. Chamber of Commerce in 1958. The House of Representatives backed National Pi Day in a 2009 resolution.

National days, federal holidays, and international days: what’s the difference?
A national day is an observance, and anyone can start one. A federal holiday is set by Congress and gives federal workers a paid day off. An international day is usually set by the United Nations or another global body.
| Type | Who sets it | Day off work? | Example |
|---|---|---|---|
| National day | A person, company, group, Congress, or the President | No | National Taco Day (Monday, October 4) |
| Federal holiday | Congress, in 5 U.S.C. § 6103 | Yes, for federal workers | Thanksgiving Day (Thursday, November 25) |
| International day | The United Nations or a global body | No | World Environment Day (Saturday, June 5) |
See the 2027 federal holiday calendar for the 11 paid holidays, and the international days calendar for UN observances.
