I should add that I grew up on a farm in the United States during the 1980s and 1990s. We “worked” on the farm of two 10 or 12 hours a day, but the majority of that time was spent not slaving away doing actual work, but moving things around. Driving tractors, animal husbandry, cleaning out barns, transporting feed or harvested crops, or the main labor intensive activities.
Additionally, we spent time doing planning and accounting, as well as ordering products and services that the form required. However, compared to working on a factory floor or in an office job the work was far lower in intensity and did not have the type of oversight that modern office labor incurs.
The other thing is that during the winter, from roughly October through February basically no work happens. Nothing grows, so the only thing you need to do is to feed your animals and keep them clean. That’s it. It’s like a 4-month vacation, although it still requires some upkeep the workload is a fraction of what you do during the rest of the year. Maybe 1 to 2 hours a day.
There’s also the fact that, before the advent of gas and then electric lighting, you really couldn’t see shit after dark. Tallow candles allow you to see where you’re going, but they don’t give off enough light to allow you to do much real work. Thus, throughout the winter there were simply fewer hours in which to do most things.
This is also likely why “dinner” was traditionally at lunchtime, and was also the main meal of the day. This was the time of day when you would most reliably have enough light to prepare a large meal. Then, when artificial lighting became a thing, upper class types started having “dinner parties” late in the evening, and for many dinner became the evening meal. It did not spread everywhere, though, in particular the north of the UK generally still thinks of dinner as lunchtime.
