September first is widely celebrated as Knowledge Day in Russia and several neighbouring countries, marking the return to school after the summer holidays with assemblies, flowers for teachers, and first lessons. Short greetings like this one circulate online each autumn as a quick way to mark the occasion, especially in short videos, classroom presentations, and messages between students, parents, and teachers. Because the phrase is instantly recognisable to Russian speakers, it continues to resurface every school year as a simple, warm opener for back-to-school content.
