During the second half of May 1929, [[Yuri Larin]] ([[:ru:Юрий Ларин|Юрий Ларин]], 1882–1932) proposed a continuous production week (''nepreryvnaya rabochaya nedelya'' = ''nepreryvka'') to the Fifth [[Congress of Soviets]] of the Union, but so little attention was paid to his suggestion that the president of the Congress did not even mention it in his final speech. By the beginning of {{nowrap|June 1929}}, Larin had won the approval of [[Joseph Stalin]], prompting all newspapers to praise the idea. The change was advantageous to the anti-religious movement, as Sundays and religious holidays became working days.<ref name="Siegelbaum1992">{{cite book|last= Siegelbaum|first=Lewis H.|title=Soviet State and Society Between Revolutions, 1918-1929|url=https://books.google.com/books?id=kog_NaF7J1YC&pg=PA213|year=1992|publisher=Cambridge University Press|isbn=978-0-521-36987-9|page=213}}</ref> On {{nowrap|8 June 1929}} the Supreme Economic Council of the [[RSFSR]] directed its efficiency experts to submit within two weeks a plan to introduce continuous production. Before any plan was available, during the first half of {{nowrap|June 1929}}, 15% of industry had converted to continuous production according to Larin, probably an overestimate. On {{nowrap|26 August 1929}} the [[Council of People's Commissars]] (CPC) of the [[Soviet Union]] (Sovnarkom) declared "it is essential that the systematically prepared transition of undertakings and institutions to continuous production should begin during the economic year {{nowrap|1929–1930}}".<ref name=Schwarz31/><ref name=Cross>Gary Cross, ''Worktime and industrialization'' (Philadelphia: Temple University Press, 1988) 202–205.</ref> The lengths of continuous production weeks were not yet specified, and the conversion was only to ''begin during the year''. Nevertheless, many sources state that the effective date of five-day weeks was {{nowrap|1 October 1929,<ref name=Parry/><ref name=Holford/><ref name=Parise/><ref name=Richards/><ref name=Zerubavel/><ref name=Atholl>The Duchess of Atholl (Katherine Atholl), ''The conscription of a people'' (1931) 84–86, 107.</ref>}} which was the beginning of the economic year. But many other lengths of continuous work weeks were used, all of which were gradually introduced.
