When is The Spring Equinox This Year?
Does anyone know when is the Spring Equinox this year 2011?
The equinox is when day and night are about the same length... although the planet's non-circular orbit mess that up a bit.
The Vernal Equinox heralds the beginning of the spring season for Earth's northern hemisphere.
I don't know the exact date and time of the Spring Equinox, can anyone help me?
