What's difference between 昼(hiru) and 正午(shōgo)?


Both 昼{ひる} and 正午{しょうご} mean noon, so are they interchangeable?




「正午」 only has one meaning --- "12:00 p.m."

「昼」 has a few different meanings --- "daytime", "12:00 p.m.", "lunch",
"afternoon", etc.

So, the two words are only interchangeable when talking about "12:00 p.m. (=
'noon')".

Strictly speaking, however, it is always better to use 「正午」 when referring to
"noon" in order to avoid any ambiguity.
