My sobriety date 18 yrs and counting just cigars and pepsi and cake to celebrate
Children's day. All amusement parks would be free to children 0 to 18; all Happy Meals and their equivalent would be free that day; of course no school; free medical and dental exams and free follow ups for anything found; all parents would be given the day off to be with their children; all adoptions would be fast tracked; all expenses for babies born that day would be paid for by the hospital; etc, etc,
In Canada, I would purpose the first warm day in the spring as a national holiday. After a long winter, I think the first time the temp goes to above 21 celesus the day becomes an instant holiday complete with a temperature count up.
In contrast, the first hot day in November ( above 21C) also becomes a holiday. Rare as it is in November, I think it could be fun.
