Then draw a line up from that point towards the centre of the wheel until it crosses the hashed ecliptic line.

The outer rim marks off the degrees (for locating planets) and dates, the inner wheel represents the time. Simply rotate the wheel to align any date and time, and the map updates to reflect the correct sky.
