Early notification of acceptance

I applied to nine schools, all of which send decisions between early March and April 1st. My acceptance letter from Whitman (to which I applied as a fallback) came on the first of March, but upon looking at their website, the posted decision date is “late March.” Should I take it as a good sign, or is that normal?

A good sign of what? I think the content (acceptance, as you stated) would be more of a “good sign” than whatever date you received it.

Definetely good, they want you/

I think OP might be asking if his/her acceptance is “good omen” for the rest of his/her schools (unless I’m thoroughly mistaken, lol).
