Today, the third Monday of January, is considered the most depressing day of the year. It’s often dubbed as “Blue Monday” because the Christmas memories are fading, the credit card bills are coming in, we’re still working off some holiday weight, getting back to the grind of work and the weather isn’t overly warm. So… what about the HAPPIEST day of the year? It is calculated to midsummer in the Northern Hemisphere, somewhere around June 21st and 24th. (Photo: Calendarpedia)
