Kennedy, these days are also considered federal holidays.^[4] There was no official day of mourning for Herbert Hoover.^[5]
• In the Soviet Union, an official mourning period was reserved for the deaths of leaders or former leaders, with Alexei Rykov, Nikita Khrushchev and Georgy Malenkov being notable exceptions after Rykov was executed during the Great Purge and the other two were relegated to obscurity. Khrushchev's death was announced only hours before he was buried without full state honors,^[6] while Malenkov's death was publicly announced more than 2 weeks after he died.^[7] This custom changed in 1968 when a national day of mourning was declared for Soviet cosmonaut Yuri Gagarin, the first human to journey into outer space.^[8][9] In the final years of the Soviet Union, official mourning was declared for 2 disasters: the 1988 Armenian earthquake and the Ufa train disaster.^[10]
