Overview

February 21 is the 52nd day of the year in the Gregorian calendar. In common years there are 313 days remaining; in leap years the count is 314, reflecting the extra day added to February in those years (leap years). In the Northern Hemisphere this date falls in late winter; in the Southern Hemisphere it is late summer. Astrologically the Sun is usually in the sign of Pisces at this time.

Historical significance

This date has been associated with a number of events across politics, war, and culture. Examples often cited include the beginning of the Battle of Verdun in World War I, diplomatic milestones in the 20th century, and notable political assassinations. February 21 has also been the publication date or anniversary for important political and ideological writings in the 19th century.

Observances and commemorations

One widely recognized observance on February 21 is International Mother Language Day, proclaimed by UNESCO in recognition of the Bengali Language Movement and in support of linguistic and cultural diversity worldwide. In Bangladesh and among Bengali communities the date is observed with ceremonies and memorials; other countries and institutions mark the day with educational and cultural programs.

Notable anniversaries (examples)

  • 19th-century political publications that influenced later movements have been associated with this date.
  • Military and diplomatic events in the 20th century, including major battles and high-profile state visits, are remembered on this day.
  • Assassinations and political deaths that shaped civil-rights histories have occurred on February 21, and their anniversaries are often noted by historians and civic groups.

Uses and cultural notes

As with any calendar date, February 21 serves as a marker for anniversaries, legal deadlines and cultural observances. Schools, museums and media commonly use the date to frame historical retrospectives. Because it falls near the end of February, it is sometimes a convenient reference point when explaining the progression of seasons, fiscal periods or personal milestones within a year.

Distinctive facts

While many days have overlapping events, February 21 is distinctive for linking language rights and cultural remembrance (through International Mother Language Day) with a number of international historical events. Its position within the calendar makes it the last week of February in common years and a moment when the approach of spring (or autumn in the Southern Hemisphere) becomes a practical concern for agriculture, travel and civic planning.
