About Knowledge Day
In Russia, the first day of school is called 'Knowledge Day' (День Знаний) and may simply be known as 1 September as that’s the day all kids in Russia, Soviet republics and former Eastern countries excluding Romania go back to school (even if this is a weekend!).
Knowledge day was established by the Decree of the Presidium of the Supreme Soviet of the USSR in June 15, 1984. The 1st September also marks the end of summer and the beginning of autumn.
It has special significance for the incoming first graders who are starting school for the first time and the kids in their final school year, which is known as year 11 in Russia.
