Red Army Day historically referred to the day that commemorated the founding of the Workers' and Peasants' Red Army in Soviet Russia. The Red Army was established on January 28, 1918, and Red Army Day was initially celebrated on this date. However, over time, the date of the celebration was changed.
In 1949, after the end of World War II, the Soviet government officially moved the celebration of Red Army Day to February 23rd. This date was chosen to coincide with the anniversary of the first mass draft into the Red Army during the Russian Civil War.
While the Soviet Union no longer exists, and many former Soviet republics have transitioned to different forms of government, some countries may still observe military-related events on or around February 23rd as part of their historical legacy. It's worth noting that specific observances and their names may have changed in different countries since the dissolution of the Soviet Union.
