Yes. In the Southern Hemisphere, the dates are switched. Winter Solstice there is Summer Solstice in the Northern Hemisphere and Samhain in the Southern Hemisphere is Beltane in the Northern Hemisphere and so on. Most of the books we get are written with the Northern Hemisphere in mind, and so is this website, so it can be confusing. If your seasons are off, please feel free to make adjustments as needed. The Sabbats are for celebrating the changing of the seasons, so if it's spring, you should be celebrating spring Sabbats even if elsewhere we are celebrating autumn.

Good question. Thanks for asking!

Morningbird is perfectly right. What we tend to forget is that paganism follows the cycles of the earth, the shifting of the seasons not the calendar holidays that we're used to in other traditions. Celebrate summer in your summer, not June 21 if that's your winter solstice.

By the same token, we cast circle in the northern hemisphere clockwise. Watch the water spin down the drain, it cycles clockwise. Unless you're in the southern hemisphere, then you'd probably cast circle counter clockwise (or anti-clockwise as some say) as that is the direction of creation.

While Sabbath are tied to the seasons, therefore they are reversed in the southern hemisphere for obvious reasons, the myth of the water spinning the other way is to be ignored :) The circles are cast always the same directions as energy and polarities are not reversed. The only real difference is that the sun at its highest is at North instead of South, so that is the only adjustment you need to account for in some of the Solar rituals.
