The Dark Day, as it was called, began around 10 in the morning. It became as dark as night outside, requiring people to use candles to go about daily life. The darkness did not clear until the following day, but by then one case safely assume everyone's natural clockwork was set off by the bizarre weather. It is thought that the cause of the phenomenon was a combination of Mother Nature's darkest elements: forest fire smoke, thick fog, and cloud cover.
Now one can only hope the current dark day New England is experiencing 231 years later will soon be gone!
