The South Korean general election, in which the electoral reforms gave 18 year olds the vote for the first time, were held on__________?

South Korea’s 21st legislative elections were held on 15 April 2020. All 300 members of the National Assembly were elected, 253 from first-past-the-post constituencies and 47 from proportional party lists. They were the first elections held under a new electoral system. The two largest parties, the liberal Democratic Party and the conservative United Future Party, set up new satellite parties (also known as bloc parties) to take advantage of the revised electoral system. The reforms also lowered the voting age from 19 to 18.
