An astrologer can take the chart reading one step further. He or she can calculate the movements of the plants over a specified period of time and use that information to forecast upcoming events, such as the best time to move, when to start additional schooling, or when to change jobs. Daily forecasts are also based on charts. Each sun sign is placed into a particular house in the chart. Next, each planet's position is calculated and also placed into its appropriate house. The astrologer then looks at what impact the movement will have on each sign. A personalized reading based on your individual chart would be more specific, but daily horoscopes still provide a general outlook. Weekly, monthly, and quarterly forecasting are calculated in this way.
