SPRING “It is spring again. The earth is like a child that knows poems by heart.”
Rainer Maria Rilke
According to the astronomical definition, spring occurs when the Sun’s rays strike the equator at noon from directly overhead. This particular time varies from year to year due to variations in the Earth’s orbit about the Sun. In the Northern Hemisphere the vernal (or spring) equinox (equi, “equal,” and nox, “night”) occurs between March 19 and 23, but usually on March 21.
