Overview
July 24 is the 205th day of the year in the Gregorian calendar and the 206th in leap years. In a common year there are 160 days remaining until December 31. In the Northern Hemisphere it falls near the height of summer and in the Southern Hemisphere near midwinter, so seasonal activities and observances vary by region.
Calendar position and characteristics
The date's position in the Gregorian system determines how it interacts with movable observances and fiscal or academic schedules. When a year is a leap year the extra day in February shifts the ordinal day count so July 24 becomes day 206. That shift can affect the timing of week-based routines, quarter ends and anniversary calculations used in civil and administrative contexts.
History and notable events
Several widely remembered historical events occurred on July 24. Explorers, diplomats and scientific achievements are among those commemorated on this date. One prominent example is the splashdown of the Apollo 11 command module on July 24, 1969, marking the return of the first crew to land on the Moon. Another internationally significant milestone is the signing of the Treaty of Lausanne, concluded in late July 1923, which reshaped borders and diplomatic relations in the aftermath of World War I.
Observances and cultural significance
