Did you know that today is the shortest (read: darkest) day of the year in North America? Today the sunset in New York will take place at 4:32pm. Zoinks!
Does it feel dark where you are? Do you ever get winter blues? It's hard not to, when the days are so dark. But! The good news is, the days will now get brighter every day for the rest of the winter. So if you can make it through today, you're all set. :)
