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?

Sunday, March 20, 2011 marks the vernal equinox, and what many people in the Northern Hemisphere refer to as the first day of spring.
At this time of year, we gain about 20 minutes of daylight each week.

Spring will start at 7:21 p.m. EST as the sun crosses into the northern hemisphere, when most of the earth will see 12 hours of both daylight and darkness.
The forecast for the start of the first week of spring is warm and inviting.
