What is Ostara?
Ostara is the spring equinox, the precise astronomical moment when day and night reach balance and the light begins to win. Many contemporary Pagan traditions name it for Ēostre, a goddess whose attestation is debated.
In the Wiccan tradition, the Wheel of the Year traces eight sabbats across the solar-lunar calendar. According to Janet and Stewart Farrar in A Witches’ Bible (1981), each sabbat carries a specific ritual logic and seasonal mood. In the earth-based pagan tradition, the names and dates we use today are inherited from Celtic, Anglo-Saxon, and Germanic sources; Ronald Hutton in Stations of the Sun (1996) describes the modern eightfold wheel as a Gardnerian synthesis assembled in the mid-20th century. Demetra George in Mysteries of the Dark Moon (1992) describes the cross- quarter sabbats (including Ostara) as the threshold points of the same lunar-solar cycle.
The vernal equinox is an astronomically precise instant: the moment the Sun's geocentric ecliptic longitude crosses 0° (the Aries point). The Sun rises due east and sets due west; day and night are nearly equal at all latitudes.
Bede the Venerable's 725 CE De Temporum Ratione mentions Ēostre as an Anglo-Saxon goddess honored in April, though her wider attestation is thin, Ronald Hutton treats the Ēostre evidence as 'tantalizing but incomplete' (Stations of the Sun, 1996). The eight-spoke Wheel of the Year is modern (Gardner and Nichols, mid-20th century). The vernal equinox as such has been astronomically marked for far longer, Stonehenge and Newgrange both align to equinox/solstice events.
Modern Wiccan and Druid practice (the Farrars; OBOD) marks Ostara with sunrise vigils, egg blessings, and the planting of literal or symbolic seeds. The egg, balanced upright on a hard surface, is a folk demonstration of the equipoise of the equinox, though physicists note an egg can balance any day with patience. CrystalStones.com describes these rituals as contemporary; we do not claim them as ancient.
Ostara is the year's first true balance point. The Sun crosses the celestial equator, the days and nights are very nearly equal, and the body recognizes, even if the calendar doesn't yet agree, that the light has won. In Hellenistic astrology this same moment is the start of the zodiac year, the Sun's ingress into Aries. Astrid would call it cardinal-fire opening; Selene names the same threshold from the body's side: this is the green return.
The sabbat takes its name from Ēostre, an Anglo-Saxon goddess attested only briefly in Bede's 725 CE writings. Modern Pagan practice has elaborated her into a richer mythology than the historical record can support, Ronald Hutton (Stations of the Sun, 1996) is honest about this. CrystalStones.com honors the contemporary practice while keeping the historical caveat: the eight-spoke Wheel of the Year is modern, even when its individual stations have older threads.
Selene reads Ostara as the moment the year stops bracing for cold and begins reaching toward warmth. Many cultures honor this turning with eggs, with seed-planting, with sunrise vigil. The cycle suggests that whatever you intended at Imbolc is now ready to ask for visible action. Hold a piece of green aventurine at dawn. Notice what is unfurling. Plant something, literally, if you have soil; symbolically, if you do not.
Crystal Cassandra reaches for green stones at Ostara, green aventurine, moss agate, and pairs them with citrine for the returning gold light. Hold one of each at dawn.
Green Aventurine carries the unmistakable green of new growth. Many people find it the most Ostara-resonant of the green stones, fresh rather than mature.
Moss Agate is the stone of slow, persistent emergence, what is rooting now and will hold through summer. Place it in soil if you garden.
Citrine catches the equinox's returning gold. Set it on a windowsill where the equinox sunrise will reach it.
Rose Quartz softens the threshold. Many practitioners pair it with green stones to balance new growth with the gentleness it requires.
Ostara that falls near the Aries New Moon doubles the initiating force, many practitioners save their boldest spring intentions for that lunation. Ostara near a Libra Full Moon dramatizes the balance theme, the Aries Sun opposite the Libra Moon makes the equinox's equipoise emotionally visible.

Ostara 2026 falls on the vernal equinox, March 20, 2026, at approximately 14:46 UTC (10:46 AM Eastern Time / 7:46 AM Pacific). Many practitioners observe the sabbat on the nearest weekend.
Easter likely takes its English name from Ēostre, the goddess Bede mentions in 725 CE, and shares the spring-rebirth symbolism. But Easter is a Christian feast whose date is computed by lunar formula and is theologically distinct. They overlap in season and symbolism only.
The egg is a near-universal symbol of new life, fertility, and dormant potential made visible. Many contemporary Pagan practices use eggs at Ostara; the symbolism predates the Christian Easter egg by millennia.
Green Aventurine, Moss Agate, Citrine, and Rose Quartz are the contemporary Pagan crystal pairings for Ostara, chosen for the equinox's themes of new growth, balance, and returning gold light. CrystalStones.com describes these as modern crystal-companions to a modern sabbat practice.
