What do we say, ”It is 10 a.m..” or “It is 2 p.m.” in Japanese?
“Gozen” means “a.m.”
“Gogo” means “p.m.”
So we say “Gozen Jyuu-ji” for “10 a.m.” and “Gogo Ni-ji” for “2 p.m.”
Please, pay attention to the words order.
In Japanese, Larger concept comes first and smaller concept last.
Thererfore, “Gozen (a.m.)/ Gogo (p.m.)” comes first and time comes last.
