The difference between 12:30am and 12:30pm? ›

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.).

Twelve thirty am would be the usual way of saying it. Alternatively, one could say half past midnight, half (past) twelve in the morning, or 00:30 (oh-oh thirty).

There is no widely accepted convention for how midday and midnight should be represented: in English-speaking countries, "12 p.m." indicates 12 o'clock noon, while "12 a.m." means 12 o'clock midnight. 12:00 a.m. 12:01 a.m.

12:30 AM is a half hour after midnight, so long as you are not using military time or the 24 hour time used in most other countries. By using those standards, it would be 00:30, and 12:30 would be a half hour past noon. It's at night, as the am means before midday.

From midnight to 11:59 noon, the time is represented as AM, and from 12 noon to 11:59 midnight, it is represented as PM.

"a.m." means "ante meridiem" which means "before midday" and p.m. means "post meridiem", which means "after midday". Consequently to use am/pm to refer to midday, (12noon) is simply wrong (and similarly midnight). The correct terms are 12 noon and 12 midnight, with times in between using am/pm.

Midday and midnight conventions

There are no standards established for the meaning of 12am and 12pm. It is often said that 12am Monday is midnight on Monday morning and 12pm is midday. This puts all the times beginning with 12 and ending with am in the same one-hour block, similarly with those ending with pm.
