When the sun totally illuminates the narrow space between the vertical plates, it is local noon and the shadow cast by the protruding needle points true north. On the summer solstice, the shadow cast by the smaller, upper solstice wings will be at its narrowest width. On the winter solstice, the shadow cast by the lower solstice wings will be at its narrowest width.

Windsor Ontario Canada Vertical Dial 874

Rather than summer and winter solstice lines, a single hyperbola indicates the route of the gnomon shadow's tip on 8 November - the day of St.Demetrius (St. Dimitrije). In fact, the gnomon is represented at St. Demetrius' sword (or more appropriately, his spear). A small bell is engraved at 10am indicating the time of morning liturgy. At about 11:15 if you look closely, you can see the subnode point (polos montaza) of the gnomon tip used for alignment during construction.
