Today is the day after the Equinox, meaning we now live a world1 dominated by Night!
After three months of slow progress, the territory of Day has been clawed away. The tyranny of sunlight has been reduced to the lesser of influences, and continues to diminish. We expect this expansion of Darkness to last at least three months, an occasion which shall be marked by celebration and merriment, gift-giving, and a fat guy wearing red.

"world" in this case meaning "northern hemisphere"
