We have an election "day", not an election "days" or "weeks" or "months.'
Election Day.
"At midnight on the evening of November 3, and as illustrated in Table 1, President Trump was ahead by more than 110,000 votes in Wisconsin and more than 290,000 votes in Michigan. In Georgia, his lead was a whopping 356,945; and he led in Pennsylvania by more than half a million votes. By December 7, however, these wide Trump leads would turn into razor thin Biden leads – 11,779 votes in Georgia, 20,682 votes in Wisconsin, 81,660 votes in Pennsylvania, and 154,188 votes in Michigan."
