This is indeed correct. We try to spread out as many specials as possible every year for everyone, but its impossible to do every anniversary every year. Thats why we tend to stick to major milestones or traditionally popular events.
Germany also has 2 event vehicles currently up for grabs, on top of the previous 2 it had in the last event. It gets more than its fair share of attention too.
They are hardly missing on "literally everything".
Russia also takes these holidays / special days far more seriously than most in any European country by the way.
