Etymology
昼 is the modern simplified form of 晝. The older form combined 日 (sun) with a component suggesting a boundary or limit, together expressing the idea of daytime. The modern form replaces the upper part with 尺, which is a simplification and not the original historical component.
Meaning mnemonic
The outer 尺 looks like a ruler measuring the day, and inside 旦 shows the sun above the horizon. Together they mark the measured daylight hours: daytime and noon.
Reading mnemonic
For チュウ, picture the sun at noon directly above you, and you say 'chew' as you eat lunch: chew -> チュウ, right in the middle of the day.
