ben wasn't trying for a longer day in terms of time he wanted a day where more sunlight would be available for activities lit not by candles but by sunlight so he wanted to adjust the habits of the people so you rose from slumber earlier and had more light available later in the day for activities in sunlight that's in the letter he sent to the publication
". . . This event has given rise in my mind to several serious and important reflections. I considered that, if I had not been awakened so early in the morning, I should have slept six hours longer by the light of the sun, and in exchange have lived six hours the following night by candle-light; and, the latter being a much more expensive light than the former, my love of economy induced me to muster up what little arithmetic I was master of, and to make some calculations, which I shall give you, after observing that utility is, in my opinion the test of value in matters of invention, and that a discovery which can be applied to no use, or is not good for something, is good for nothing. "
" estimating seven hours per day as the medium quantity between the time of the sun's rising and ours, he rising during the six following months from six to eight hours before noon, and there being seven hours of course per night in which we burn candles, the account will stand thus;--
In the six months between the 20th of March and the 20th of September, there are
Nights 183
Hours of each night in which we burn candles 7
Multiplication gives for the total number of hours 1,281
These 1,281 hours multiplied by 100,000, the number of inhabitants, give 128,100,000
One hundred twenty-eight millions and one hundred thousand hours, spent at Paris by candle-light, which, at half a pound of wax and tallow per hour, gives the weight of 64,050,000
Sixty-four millions and fifty thousand of pounds, which, estimating the whole at-the medium price of thirty sols the pound, makes the sum of ninety-six millions and seventy-five thousand livres tournois 96,075,000
An immense sum! that the city of Paris might save every year, by the economy of using sunshine instead of candles."
