Depends on the area but they were constantly busy. Warm seasons were 7 days a week sunup til sundown.

For the cold seasons:

• Wheat and barely were sown in the winter so that when spring showed up the crops sprouted and grew quickly
• Logging/forestry work as well as trapping
• Mending of tools, spinning of wool/flax into usable fabrics
• Weaving baskets/clothes etc
• Processing of slaughtered game into foodstuffs
• Processing & protection of food stores
• Repairs to your house
• Ice fishing to augment stores of food
• Building and fixing fences
• Distilling and pickling foods
• Generally anything that improves your chance of survival

And of course:

Hoping and praying that they had enough food to not starve to death.
