How about "the sun is approximately overhead at noon", "the sun is at its highest point in the sky at noon", "the sun rises each day", "noon is approximately the time that people eat a midday meal", or "midnight is a good time to switch which day 'tomorrow' refers to".

I've made many mistakes attributable to "tomorrow" switching at midnight according to computers when in common human usage "tomorrow" really switches closer to sunrise, and certainly not before one goes to bed unless one is staying up all night.
