Why US elections are on Tuesday that too in NOV?

Hi, on Nov 3 2008 that is on Tuesday the US Presidential elections have been conducted. But why on Tuesday that too in the month of November?

Well, every time the elections are conducted in the month of November and that too after first Monday i.e. on Tuesday this is because

-> In 1845 America was known for farming (i.e. for agriculture)

-> On Sundays people go to church, so Sunday is meant for worshiping and taking rest

-> in those days people have to travel long distances in order to vote, so Monday was meant for traveling.

-> Wednesday is market day, so they thought Tuesday was fine.

Why on November?

-> Because by November harvesting will be done and the whether will be fine to travel.

Why after first Monday ?

->Elections were held after first Monday because it will never fall on Nov1 which is All Saints Day.

-> still they follow it.
