1900 Military Time Secrets: How This Time System Changed WWI Forever! When World War I erupted in 1914, military operations were revolutionized—not just by machines and trenches, but by an unexpected yet critical tool: the military time system, rooted in the 24-hour format. Although it had existed since the late 19th century, military time transformed how armies coordinated complex battlefield strategies, logged operations, and communicated in the intense context of WWI. This time standard, often called “military time,” enabled precise scheduling, reduced confusion, and laid the operational foundation for modern warfare. Let’s uncover the hidden secrets of how military time changed WWI forever. ### The Rise of Military Time in the 1900s The 24-hour clock—also known as military time—originated from earlier military and astronomical traditions, particularly in 19th-century Europe. By the 1900s, many European armies adopted this system to eliminate ambiguity during critical operations. Unlike the 12-hour format with AM/PM, military time uses hours 00 through 23, eliminating confusion during round-the-clock shifts in trenches, command posts, and transport hubs.
