To dream of an almanac represents following advice, looking ahead, or solving problems based on assumptions. Following a course of action based on what is expected or assumed. Consideration of probabilities.
Negatively, an almanac may be a sign that you need to think more for yourself or take more precautions to ensure stability. It may be a bad idea to allow assumptions to guide your decisions or make risky choices without considering the unexpected. Overestimation or underestimation that a situation will turn out perfect.
