I'm not talking about astronomy, I'm talking about how humans have
implemented "day" in their daily lives.

China is one big timezone, DST also exploits the vast tolerance
humans have for where the sun is in the sky when they eat.

So yes, it may be the "synodic day" but it is "the synodic day
with a precision of about 1/6 rotation or so"
