I used the names Ostara and Eostre because they are the ones where the name previously came from
Older goddess's of the equinox and of spring time include Eirene, Irene and Eiar, Persephone, Jarylo, idun and most ancient of all Senua,

These were the goddess' of Imbolc (the dawn of spring) to the equinox

@David_Cooper
Bunnies, are not at all recent the Brown Hare and the Chicken were venerated by the ancient Britain's as the representative of the gods on earth, for their fertility, speed agility and survival prowess.
Though domesticated Rabbits did not come to the Uk until the time of the Romans, their cousin the Hare was often seen as the earthly personification of the Goddess Bridgid goddess of spring, fertility, and life.
Her appearance on a battle field guaranteed victory to the tribes who worshipped her, Boudica kept one as an advisor and conduit to the Goddess in her war against ancient Rome.

@LenHazell53 Bridgit was so popular that the Xtians couldn't get rid of her--so they turned into a Catholic saint.

@Gwen_Wanderer She wasn't the only one, thanks for reminding me of that

@LenHazell53 the Xtians also built churches on sites sacred to the Druids and other pagan religions. The Green Man and Sheela-Na-Gig are portrayed in churches. Have you seen any of the, ahem, inappropriate carvings left behind by the construction crews? If not, I hope the pic on the link does not shock you.

Yes my wife is Druid and it is well known in her community that a "fascinus" or "fascinum" was often placed inside the alters of Christian churches or worked in to their carvings, so that the old religion could continue subversively inside the "Holy" places.

@LenHazell53 much to the fascination of us in the modern era!

The date does not just move because the equinox is not on the same day every year, which only varies it by a day or so, but mainly because it is fixed at the first full moon after the equinox. Which means that it also varies by a lunar month, depending on how the lunar months fall.

You are therefore in the crazy situation of using three different cycles to calculate it, the historically conventional solar based calendar of twelve imaginary months, the actual astronomical solar calendar and a lunar cycle.

@Fernapple yes, thanks for elaborating.

, @David_Cooper I am sure that many atheists accommodate Xtian relatives. My son is an atheist, but he "celebrates" Easter as that is when my DIL's family does so. The same for Xmas--

@David_Cooper Yes I think that we should celebrate the equinox rather than the Christian date. But in fact, I think that there is already a trend going to do so. As there is a trend also to celebrate the solstice, and call it Yule.

@Fernapple when people wish me "Merry Xmas," I say, "Thanks, but I celebrate the solstice." They rarely have a clue what I am talking about.

@Gwen_Wanderer Sorry to sound smug. But I think that in the UK most people would, sadly perhaps, our media and education systems are more broad minded.

OR because they liked to party.....

@David_Cooper No, I said that changes are big at the equinox, it is at the solstice that they are small, that is why it would make more sense, for early people to find the equinoxes and then count the days from them to find the solstices, rather than the other way round.

@David_Cooper Perhaps yes that could well be the case. You are correct, except how do you locate the solstice ? While you could easily measure shadow length, and find a half way between the solstices.

@David_Cooper And of course the fact is that we know that many ancient peoples only had the solstice to three or four days, yet they had the equinox exactly.
