Do you have a major upcoming event? In astrology, an event chart is a horoscope that is cast for the date, time and place of a particular event. Such a chart is interpreted to gain insight into influences surrounding the event and an outlook for possible developments stemming from that event. For example, astrologers can read a chart for your major event, such as a marriage, and interpret it as though the event were a person in its own right. For example, if a chart was cast for the date of one’s marriage then the chart would give an indication of what the couple can expect during their married life.
