Key Facts

Overview

15 January is the 15th day of the year in the Gregorian calendar, with 350 days remaining until the end of the year (351 in leap years). This date falls in the middle of January, the first month of the year, and often marks a period of reflection and resolution-setting following the holiday season. As the third week of the year, it is a symbolic time for many cultures to solidify new year commitments and initiate long-term plans.

The historical significance of 15 January spans multiple centuries and continents. It has been associated with pivotal political, cultural, and scientific developments. For instance, 15 January 1929 marked the birth of Dr. Martin Luther King Jr., one of the most influential figures in the American civil rights movement. His leadership in nonviolent protest reshaped U.S. civil rights legislation and inspired global movements for justice and equality.

Another major event occurred on 15 January 1949, when General Kodandera Madappa Cariappa became the first Indian Commander-in-Chief of the Indian Army, succeeding British officers after independence. This moment is commemorated annually as Army Day in India, a national observance featuring parades, military demonstrations, and tributes to fallen soldiers. Additionally, 15 January 1988 marked the founding of the National Geographic Society, which has since become a global leader in exploration, science, and environmental advocacy.

How It Works

The significance of 15 January varies depending on cultural, national, and historical contexts. In some countries, it is a day of celebration; in others, a solemn remembrance. The way this date is observed often reflects broader societal values, such as patriotism, scientific progress, or human rights.
