Appendix C: The dark Day of 1780

New England’s Dark Day occurred on May 19, 1780, when an unusual darkening of the day sky was observed over the New England states and parts of Canada, even extending as far south as New Jersey. The primary cause of the event is believed to have been a combination of smoke from forest fires, a thick fog, and cloud cover. (Wikipedia)
There is also another rational theory that has been presented, that of a fulfillment of Bible prophecy.
The 1869 edition of Webster’s Dictionary has the following entry. “THE DARK DAY, May 19th, 1780 so-called on account of a remarkable darkness on that day extending over all New England. In some places, persons could not see to read common print in the open air for several hours together. Birds sang their evening songs, disappeared, and became silent; fowls went to roost; cattle sought the barnyard; and candles were lighted in the houses. The obscuration began about ten o’clock in the morning, and continued until the middle of the next night, but with differences of degree and duration in different places. For several days previous, the wind had been variable, but chiefly from the south-west and the north-east. The true cause of this remarkable phenomenon is not known.”
Due to wind conditions and the large area affected by this strange darkness, it seems that there was more going on than publicized by the scientific community.
