Question: 12.30 in the morning is am or pm?
Answer: 12:30 a.m. is in the first period which begins at midnight (technically 12:00 a.m.) and the 12:30 p.m. is just after noon (which technically is 12 p.m.). To avoid confusion, many people do not use 12 a.m or 12 p.m. and prefer to use midnight and noon.
