Hi.
As Americans sometimes do, we moved the summer solstice to Memorial day so the date moves around again.
5.56mm
And we moved the autumnal equinox to Labor Day.

No, as a matter of fact, we haven't. The 100 year skip of February 29 was itself skipped in 2000. That has had a small impact (a shift of one day) on some of the upcoming equinoxes and solstices.
