Today is the first day of spring. The vernal equinox was last night at 11:49 p.m. MST. Of course, for those in the southern hemisphere, like some of L's relatives, it is the first day of autumn.
"The first day of spring is one thing, and the first spring day is another. The difference between them is sometimes as great as a month."
-- Henry van Dyke, Fisherman's Luck
