Spring Equinox

Today is March 20, 2009 and it is the Spring Equinox. This happens twice a year. On a day of an equinox, the center of the Sun spends an equal amount of time above and below the horizon at every location on the Earth, night and day being the same length.

Two observers at the same distance north and south of the equator will experience nights of equal length.

Today marks the first day of spring. Maybe this is why I’m having so many allergic complications, I can’t breath! We can depend on the sun being out later giving us more daylight. Today is also celebrated as Mothers Day in Arab nations. Something we should celebrate every day.
