That said, I don't consider an observation
of Yule (fact: this was a Germanic pagan
tradition LONG before the birth
of Christ) or Eostre / Ishtar / Easter (all sorts
of convoluted Roman and pagan
traditions regarding
celebration of spring and death / resurrection were happening around this time
of year prior to Christ's existence) to be favoring one religion over another, since so many different religions are involved in those mixes.
A New Beginning: Celebrating the
Spring Equinox - Wendy Pfeffer I really enjoy this series
of seasonal books for the wide perspective
of celebrations and
traditions they provide.
