The spring equinox isn't for another 11 days.

But the traditional date is Risshun, which is February 4 (which is around the cross quarter... making the equinox mid-spring). Meteorologically speaking, the beginning for Japan is the beginning of March. So in those ways, she's late.

Is she wearing skates? It looks as if she did, but they shouldn't come off so easy and I assume it's her footwear flying in panel three.
