More esoteric research

Winter solstice will play an important part in BEWITCHED, thus I needed to find out on which date the solstice fell in 1820 (or rather in the years 1817-21 because I still haven’t quite decided in which year the story is set) (well, I’m using quotations from Byron’s “La belle dame sans merci”, which was first published in 1820, so I’d better not set the nove lin 1817 …). Anyways, found this lovely site where you can calculate the dates of solstices and equinoxes: here.
