I don't remember such a holiday.
It is likely that there was something similar once, but in Soviet Times the holiday "Agricultural Worker's Day" was introduced, which is celebrated on the second Sunday of October. It turns out he was there last week. In our country, they still like to celebrate various Soviet holidays, especially professional ones.
I requested "autumn holidays in Russia," and Yandex gave me a list. There are a lot of professional military holidays there, which made me sad.
When we were young, we used to have an autumn ball at our club in the village.
