"Night after night goes by: and clocks still chime
And stars are changing pattrns in the dark"
from "Two O'clock" by Christopher Morley

Why then turn the hands backward or forward seasonally?

To those who celebrate #Samhain, may you have the #blessings of #harvest, #hearth, and #home this #season.

A close-up photograph of a lit white candle with a flickering flame, positioned in an ornate metal candlestick. The candle is surrounded by a warm autumnal scene, featuring a harvested arrangement that includes pumpkins, red apples, and fall leaves. Wisps of smoke rise delicately from the candle's flame, creating a tranquil atmosphere. The background is dark, allowing the colorful elements in the foreground to stand out, reinforcing the seasonal theme of warmth and coziness associated with autumn. An orange cloth is draped beneath the scene, further enhancing the autumnal aesthetic.

Roughly halfway between #autumnalequinox & #wintersolstice, we celebrate the changing of the #seasons, the coming of #winter:
#Halloween
#AllHallows
#DíadelosMuertos
#Samhain
the 4th #crossquarterday

Take a moment to enjoy the #sky, as did those who worked out our #calendar.

The diagram features a spherical representation of Earth positioned at the center, with labeled points indicating the Autumnal Equinox, Winter Solstice, Vernal Equinox, and Summer Solstice located along the ecliptic plane, which is denoted by a blue arc. Red crosses mark specific points identified as the 1st, 2nd, 3rd, and 4th cross-quarter days, positioned between the solstices and equinoxes. The North Celestial Pole (NCP) and South Celestial Pole (SCP) are indicated by vertical arrows.

Today I'm going to talk about the Hebrew calendars. Yes, that's calendars, plural. Jews aren't the only Hebrews; Samaritans are also still around and they have their own traditions, including their own calendar.

Atomic clock nerds at #MIT have finally figured out how to make a #watch that’s slightly less wrong, still not helping anyone get to work on time. ⏰🔬 Meanwhile, the rest of us are just trying to remember where we left our keys. 🗝️🌀

Two concentric wooden dials mounted on a circular wooden backplate with a decorative handle at the top and a point at the bottom. The outer dial has a long arm extending outward. The backplate and central dial have circular scales inscribed on them.

It’s amazing how such a small phrase like “o’clock” carries centuries of history! This article gives a whole new meaning to something we use every day. ⏰ #Timekeeping #History #OCLock

Hackaday: Clock Of Clocks Expands, Goes Digital. “Some people just want to have their cake and eat it too, but very few of us ever get to pull it off. [Erich Styger] has, though with V5 of his ‘MetaMetaClock’— a clock made of clocks, that uses the orientation of the hands to create digits.”
