How to read 0030
0030 is in the first hour of the day, the 12 AM hour: replace 00 with 12 and add AM. So 0030 is 12:30 AM, 30 minutes after midnight.
Hour 00 reads as 12 on a 12-hour clock, and it is AM.
This is the hour people most often get wrong going the other way: 12:30 AM is 0030, not 1230. 1230 is half past noon.
0030 falls in the small hours of the night: 30 minutes after midnight, 2.1% of the way through the day, with 23 hours and 30 minutes left until the next midnight.
How to say it
Pilots and air traffic controllers say each digit: “zero zero three zero”. Off the radio, people usually read 0030 as two numbers.
