Have you heard of an ice day? Most of us are familiar with snow days – where school has been cancelled because of bad weather. Ice days are a little different. In fact, the term isn’t used much in the United States. But in Great Britain, and much of Europe, it refers to a day when temperatures don’t get above 32 °F, and ice on the surface of water doesn’t thaw. In Manhattan this January, we had 12 ice days. Which would mean a lot of extra school days this summer, if they were like snow days.
