1 more hour thought experiment

[Froge]

What do you think the social, cultural, economic, religious, and political implications would be for society if an extra hour was added to the day, all else held constant (eg. school length, work hours)? The length of a year would definitely change, first of all.

Note: there is no scientific basis for the extra hour. The hour is added because Chronofrog has been crowned supreme overlord of humanity and he demands 25 hour days.
