The actual solstice won't occur until 5:30 UTC tomorrow morning, but I think it's traditional to celebrate it on the 21st, so that's what I'm doing. The time that starts now is a time for renewal; time to leave the past behind and move on. Pay your debts, wrap up what needs to be wrapped up, and drop any emotional baggage and look forward; start with a clean slate, and look forward to new year and the proverbial turning of the great wheel. And of course, be happy with what you've got, celebrate, eat good food and spend time with friends and loved ones.
Enjoy the longest (or shortest) night!
