I don’t have a specific connection to Eostre above other holidays, but, well, playing with letters and such… My exposure to the pagan holidays started with the Wiccan versions of them, centered on the journey of the Goddess and the God throughout the year. As I ventured off that path and onto generalised Paganism with a center on nature, I also took the holidays for their more seasonal nature instead of the metaphorical journey. As such, I generally observe the solstices and equinoxes and refer to them as such. The other holidays in between, I know of them, and I appreciate them, but I do not generally observe them.
Midwinter
Also commonly known as Yule. It is the time of the shortest day of the year, a moment to acknowledge that the deep of winter is here, and from now on we move again towards the light. A festival of rest, really, as many things are in slumber and the weather is (generally) not conducive to much activity outside the house. As the world is clad in darkness, it is also a festival of light and warmth. Literal light and warmth from candles, hearth fire, but also metaphorical light and warmth from spending time with friends and family. A moment to show your appreciation of them by sharing your home, your food, and gifts.
Spring Equinox
Here’s the titular Eostre 🙂 A festival for the awakening of the earth. Spring is at hand and it shows in the emergence of new life. Weather is improving and as such people drift back outside. A time to appreciate the new and the young, to revel in what the earth has to offer. A time, also, to work and prepare the land, sow the seeds and help new life come into existence.
Midsummer
Also referred to as Litha. It is the time of the longest day of the year, the opposite of midwinter. Time to give thanks for the light as we realise it will wane as we journey towards the darkness of winter. Life is at its height, animals are full, plants are lush, there is no shortage of food, and as such it is the perfect moment for grand celebrations.
Autumn Equinox
Otherwise known as Mabon. Winter is getting closer and humans and animals alike prepare for it. Harvests are ready and brought in, food is stockpiled and animals that sleep through the winter eat themselves round. It is again a time to work, but this time we bring things inward, into the home, instead of outward, into the land.
