Not very. They depend on the seasons of the year, they had to be positioned correctly, and there are additional factors that slightly affect their accuracy, such as the fact that the Earth's orbit is observed to change slightly every year. Additionally, how would you tell time on a cloudy day? But for the purposes they served, they were accurate enough until better technology came along.
