Just after dawn this morning, the sky shows a lot of blue, but the sun has not yet reached the buildings. The Christmas tree (center, in shadow) will not be lit until the official ceremony tomorrow, although it is already covered with decorations. Merchants will open soon; this is "Black Friday", from the expression "
In the black", meaning profitable. The term comes from old hand written business ledgers, where profits were written in black and losses were written in red. In the US, retail sales are highest in the weeks before Christmas, and since the day after Thanksgiving is usually a day off work for most people, it has become an especially important sales day for retailers.
