Overview

March 4 is a date in the Gregorian calendar that normally falls as the 63rd day of the year; in leap years it is the 64th day. The date sits in late winter in the Northern Hemisphere and late summer in the Southern Hemisphere. Its placement in the calendar means it precedes many movable observances that depend on the date of Easter and other shifting calendars.

Calendar position and characteristics

As part of the modern civil calendar, March 4 is fixed in month and day. In common years it follows March 3 and precedes March 5. Whether the day is the 63rd or 64th day depends on the occurrence of a leap day earlier in the year; see leap years for how that adjustment is made. The underlying system is the Gregorian calendar, the international standard for civil use.

History and notable institutional role

March 4 has had particular historical significance in the United States. From 1793 through 1933 it served as the official Presidential Inauguration Day, the date on which newly elected presidents and vice presidents were sworn into office. That practice began in the early federal period (1793) and continued through the early 20th century. Constitutional and legislative changes shifted the inauguration schedule in response to concerns about lame‑duck periods and transition intervals; the change took legal effect after the ratification and implementation of the relevant amendment, and from the 1937 inauguration onward the ceremony has been held on January 20. The formal change was authorized in the early 1930s (1933) and the new date is commonly cited as January 20. For background on the office and ceremony see general references on the President of the United States.

Observances, cultural notes, and examples

Many countries and communities mark March 4 with a mix of official and informal observances. Some modern commemorative days—established by organizations, charities, or interest groups—fall on March 4; these are often nationally or culturally specific rather than universal. The date has also been used in literature, music titles, and as a linguistic play (for example, the phonetic likeness of "March Fourth" to "march forth" is sometimes used in names and slogans).

  • Seasonal context: late winter in the north, late summer in the south.
  • Institutional history: former U.S. Inauguration Day (1793–1933), change implemented in the 1930s leading to January 20 inaugurations from 1937 onward (1793, 1933, 1937, January 20).
  • Calendar mechanics: ordering depends on leap year adjustments within the Gregorian system.

Notable facts and distinctions

As with any date, March 4 is associated with a wide variety of historical events, births and deaths, and cultural moments across different years and places. The concentration of specific incidents varies by region and period; encyclopedic and historical calendars record those events year by year. The date's most widely cited institutional distinction is its former role in U.S. presidential transitions, a change often cited in discussions of constitutional timing and the mechanics of government turnover.
