Frequently Asked Questions
It is generally considered to have lasted from 1 September 1939 to 2 September 1945.
Both 'II' (Roman numeral) and '2' (Arabic numeral) are acceptable, though formal writing often prefers 'World War II'.
World War I (1914-1918) was primarily a European conflict. World War II was truly global, involving Asia and the Pacific from the start, and resulted in far greater casualties and the use of nuclear weapons.
Typically, no. You say 'during World War II', not 'during the World War II'. However, you would use 'the' if it's part of a descriptive phrase like 'the Second World War'.
