I responded the way I did basically because the original posting was clearly inaccurate (I don't know anything about modern "neo-pagan" ideas).
Firstly, the vernal equinox was never in the Eostre (easter) month. Secondly, the name Eostre (pronounced Easter) was only ever mentioned historically by Bede and he said a month, not a day was named after her. Thirdly, it seems reasonable to call a goddess Eostre, and worship her if you want, but why give her a nonexistent day in somebody else's month?
