Pleiades Rising

The Celtic Year is split in 2 halves, Summer's Beginning (Beltane) and Summers' End (Samhain). The position of the Pleiades (also known as the Sieve or an Criathar in Irish) in the sky is the marker for the seasons. Samhain begins when the Pleiades rise at sunset.

The Pleiades' high visibility in the night sky has guaranteed it a special place in many cultures, both ancient and modern. To the Greeks, they are the Seven Sisters.
To the Vikings, they are Freya's Hens
To the Maori, they are Matariki
To the Ban Raji, in western Nepal and northern India, they are the "Seven sisters-in-law and one brother-in-law"
To the Japanese, they are known as Subaru
In Arabic, they are known as al-Thurayya
In the Bible, they are mentioned as Khima and Talmud
