ResearchBuzz: Firehose<p>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.”</p><p><a href="https://rbfirehose.com/2025/08/10/hackaday-clock-of-clocks-expands-goes-digital/" class="" rel="nofollow noopener" target="_blank">https://rbfirehose.com/2025/08/10/hackaday-clock-of-clocks-expands-goes-digital/</a></p>

Because their relationship had no future; it was always stuck in the present, obsessively measuring every passing nanosecond!
The Babylonians seem to have used tithis even before the Indians. We don't know what, if any, name they used (hence modern scholarship just uses the Sanskrit term), but it seems quite likely the Indians learned the idea from the Babylonians.
There are some vague hints that the Greeks also learned about tithis from the Babylonians, but the evidence there is unfortunately scanty.
boring thread about time and computers
Marduk made made the moon appear and entrusted to him the night. He designated him as the night’s adornment, to define the days. Every month without ceasing he exalted (him) with a crown. “To light up over the land at the beginning of the month, you shine with horns to define six days and on the seventh day a half crown!
—Enúma Eliš explains why there are seven days in a week.
Busy day at Stonehenge as the stones are moved forward one hour
Stonehenge is one of the world's most iconic prehistoric monuments, but did you know that parts of it have been moved in modern times? This fascinating image shows a moment from the 1950s restoration efforts, but with a humorous twist—it almost looks like the stones are being adjusted for daylight saving time! Of course, no one is actually resetting Stonehenge for daylight saving time—but this real historical photo from the 1950s restoration efforts makes it look that way! The Real […]Homer (not Simpson), Hesiod, and Euripides describe the beginning of Winter as being when the Pleiades, the Hyades, and Orion set just before sunrise, at the same time as Greeks hear crane calls.
When they were writing, this would have happened around the halfway point between the southward equinox and the southern solstice, same as how the Celts and Chinese reckon the seasons.

The Borana group people into age-based and generation-based groups, which are completely independent.
Every eight years, leadership passes to the next generation group in an endless cycle. Historians identify time not by years, which are a little vague in Borana philosophy, but by which generation group was in authority at the time.
Legesse literally wrote and entire book about this, which I got from Anna just for the calendar stuff.
Thank you for reading.

Today I want to talk about Borana timekeeping. This is hard to do without getting into anthropological controversies, and it's not every day I get to disprove a widely-repeated idea. (I am not the first to disprove it but I did it independently).

Hackaday · Telling Time Used To Be A BallIf you watch the New Year’s festivities from New York, you know that they mark midnight with the dropping of a big, gaudy ball. You might assume this was just an arbitrary gimmick, but it tur…

The issue here is that 28 days doesn't match up with any lunar cycles. The synodic month is a shade over 29½ days long, so any timekeeping system that synchronises with the phases of the moon will have months of 29 or 30 days.
The sidereal and draconic months are just over 27 days long; months that synchronise with those moon cycles will occasionally be 28 days long, but will more often have 27 days.
