12. Last Day of Decade Holiday
The last day of each decade (Dec. 31, 1999, 2009, etc.) should be a national holiday, just like New Year’s Day. At the very least, the last day of each century should be a national holiday.
To give such a day a little more significance than just being a holiday for the last day of the year, perhaps it should be dedicated as a national day for cleaning and organization so that everyone would be encouraged to clean and organize their possessions, such as homes, cars, clothes, equipment, papers, etc., before the year is out and be ready for the new year when it arrives.
