A "Showerthought" is a simple term used to describe the thoughts that pop into your head while you're doing everyday things like taking a shower, driving, or just daydreaming. The most popular seem to be lighthearted clever little truths, hidden in daily life.

Here are some examples to inspire your own showerthoughts:

Rules

  1. All posts must be showerthoughts
  2. The entire showerthought must be in the title
  3. No politics
    • If your topic is in a grey area, please phrase it to emphasize the fascinating aspects, not the dramatic aspects. You can do this by avoiding overly politicized terms such as "capitalism" and "communism". If you must make comparisons, you can say something is different without saying something is better/worse.
    • A good place for politics is c/politicaldiscussion
  4. Posts must be original/unique
  5. Adhere to Lemmy's Code of Conduct and the TOS

If you made it this far, showerthoughts is accepting new mods. This community is generally tame so its not a lot of work, but having a few more mods would help reports get addressed a little sooner.

Whats it like to be a mod? Reports just show up as messages in your Lemmy inbox, and if a different mod has already addressed the report, the message goes away and you never worry about it.

The day should start at like... Equatorial dawn or something.

Maybe new words would fix it.

But even from the historical perspective it doesn't make sense. Why wouldn't they pick dawn as the natural starting point of the photoperiod? As you said, nobody was awake at night, so why did they choose a time when nobody was awake to make the differentiation on the date?
When you say "sunrise varies quite a bit", that's only from the perspective of a midnight-centric time measurement; sunrise wouldn't vary, it'd be the start of the day by definition.

There are some issues with using dawn, but they wouldn't be a concern historically and we have modern solutions;
Like days wouldn't be exactly 24 hours, and dawn is affected not just by latitude but also geography.

But fundamentally it's more satisfying if a calendar day is compromised of one single contiguous day and one contiguous night 😌
