It depends on how your house and yard are oriented. The Sun will rise higher and higher in the sky between March and the June Solstice, then sink farther down in the sky between the Summer Solstice and September's Autumnal Equinox. Areas facing south will get the maximum possible light. Northern portions of your yard will be most frequently shadowed by objects, trees, and your house so that during the daytime, they get less direct sunlight. This is why the northern part of a tree trunk often has moss which prefers shaded areas. The details of exactly what spots will get the most sunlight depend on the location of trees and other objects to the south of the area of land you are worried about. Also, there is a large latitude effect. Near the equator, the Sun passes directly over head, and it is irrelevant which direction your plot of land faces. Near the arctic regions, some parts of your yard will never see direct sunlight at any time of the year!
