How early did a medieval blacksmith get up?

Answer 1

Daylight dominated the schedules of people in the middle ages. Daylight was the only really bright light available, so people, including blacksmiths and other craftsman, tended to rise early, eat a light breakfast, and get to the work of the day as soon as there was adequate light. Work days were longer in Summer than in Winter, as there was more available light. Work days ended when the sun went down, and medieval people would likely spend the dark hours indoors, lighting their dwellings with firelight. Candles and lamps were known, but candles were expensive and dim unless used in large numbers.
