Every year annual horoscopes can be cast at the exact time of entry of Sun in Aries. Normally the chart is read like any other mundane chart. But, in an annual chart there are few additional indications given for each of the grahas. The days lord (Vedic Weekday lord) of sun's entry into various points in zodiac is also noted. These weekday lords have various significance as given in the above table. The chart should be always for the Aries entry though the dates/days for sun's entry in other positions are in future.
