Election Day (tomorrow)

I was at my allergist’s office last month for my every-28-day injection, and she asked if I wanted a reminder card. “Nah, just tell me the date.” “November 5.” “Oh, that’s Election Day, easy to remember.”

This led to me mentioing that Election Day is the first Tuesday after the first Monday in November, so it will fall on November 2 through 8, but NOT on the 1st. When asked WHY, I admitted that I didn’t know, but that it was probably tied to the fact that it was All Saints Day, and/or it’s easy to forget that a new month has started.

So what IS the real story why Congress (in 1845) select the first Tuesday in November as Election Day?
