Here's a nice story about the Stonehenge Solstice celebration. Kudos to the author for understanding how to capitalize.

And, here's another nice one about Icelandic Asatru and other Pagans celebrating the returning sun. Kudos again for correct capitalization.

Sadly, not everyone seems to have gotten the message:

In their quest to bring the Christian religion to the pagan people of Western Europe, the Church cleverly incorporated existing festivals and rituals into the Christian calendar. One of the many correlations between ancient winter festivals and Christianity revolves around the older Celtic name for the festival of Alban Artuan – or the “Light of Winter”. When deciding where to put the Christian celebration of Jesus’s birth, it is little wonder that they chose this festival to herald the arrival of the “Light of the World” – a human beacon of hope and light into a time of darkness.
It is thought that pagans may have been the original “tree trimmers” as they brought greenery into the house as a symbol of life through the long dark nights. The evergreen was brought in and adorned with decorations to symbolise the various stellar objects that were important to them; the sun, the moon, the stars. These also served as gifts to the pagan gods.

Dear Caledonian Mercury, If you capitalize "Christian," then you should capitalize "Pagan." If you capitalize "Christians," you should capitalize "Druids." It's not complicated.
