On October 16, 1964, China conducted its first atomic bomb test at the Lop Nur test site. This event marked a major milestone in the history of nuclear weapons, making China the fifth nation to possess nuclear capability. The device had an estimated yield of about 22 kilotons of TNT, and its detonation attracted significant international attention. The test was part of China's nuclear program, aimed at strengthening its global position and ensuring national security. After this test, China officially joined the group of nuclear-armed states, which affected the balance of power both regionally and globally. The event raised concerns about nuclear proliferation and intensified the arms race among major powers. The first Chinese atomic bomb test is often cited as one of the most significant military developments of the twentieth century. This date is recognized in the Gregorian calendar as the beginning of China's nuclear era. It was added to the Gregorian calendar after the event in 1964 to commemorate this significant historical and military development.
