If I remember the almanac correctly, in a little under 4 hours it shall be that time of celebration or otherwise an instant of import, as the seasons click over into the next quarter of their cycle. For those of us at the top half of the world the days (or hours of light, therein) shall once more be getting longer, whilst those on the
other, albeit inverted, top half of the world will be finally be starting to be finished with those blasted long periods of daylight and be able to get a decent night's kip, or something, in a month or three... (Forgive me, people betwixt the tropics, for I shall be ignoring you and your situation, for the sake of having insufficient descriptive language to apply to your case...)
Where the demarcation is observed in what
I at least consider to be the traditional astronomical way, this here mid-winter's/mid-summer's solstice is also the official start of Winter or Summer (despite the aformentioned 'mid-'). For those that have it artificially shifted to the 1st of the month, that's your government or other civil authority for you. I'd vote them out of office, if I were you[1]. For those that have the seasons officially bisected by each quarter-point, that may indeed be sensible but it's not mine. Any
other system has got to be fairly crackpot and even more arbitrary than the first of the alternatives, but never mind...
Anyway, as I won't be online at the moment itself, I thought I'd be a bit pre-emptive.
And so I say to you all, Season's Greetings. Mostly in its astronomical sense, although you're welcome to take it in any other manner you personally subscribe to, albeit it
is a bit early (or slightly late) for most other events hovering around this time of year.
[1] Good advice, regardless, probably.
