Calculation of Day Length Change

To calculate the change in day length from October 7th to November 19th, we need to subtract the new day length from the original day length.

Let's assume the original day length on October 7th was x hours. According to the information provided, the day length decreased by 3 hours and became 8 hours on November 19th.

So, the equation would be:

x - 3 = 8

To find the original day length on October 7th, we can solve this equation:

x = 8 + 3 = 11 hours

Therefore, the original day length on October 7th was 11 hours.

Please note that the search results did not provide specific information about the day length change from October 7th to November 19th. The calculation above is based solely on the information provided in the user's question.
