October 1 is Heijastinpäivä in Finland. Heijastin = Reflector and Päivä = Day. So happy Reflector Day to You! That means we should get out our reflectors and prepare for darkness to fall. Winter is coming! Reflectors should even be given to your pets. We want everybody to be safe on the street.
Have you ever heard of this kind of celebration? I wonder if there is such a day in Estonia, Sweden, Greenland, Norway, or Denmark?
Moomintroll reflectors are really popular in Finland!
