What is 11:15 AM in Military Time?

Step-by-Step: Converting 11:15 AM

How to Convert AM/PM to Military Time

There are two main methods of displaying the time. The first one is the 12-hour clock which uses AM and PM, and the other is the 24-hour clock.

In 12-hour clock or 12-hour time notation the day is split into two 12-hour periods running from midnight (12:00 AM) to noon (12:00 PM), and noon to midnight.

In military time the day runs from midnight to midnight and is divided into 24 hours from 00:00 (midnight) to 23:59.

Military time or 24-hour military notation consists always of four digits. It starts at 0000, which corresponds to 12:00 AM. Thus, 12:00 AM = 0000 (subtract 12 hours). After 12:59 AM the 12-hour clock jumps to 1:00 AM = 0100 in military time.

Conversion Rules

From 12:00 AM to 12:59 AM, subtract 12 hours:

• 12:00 AM = 0:00 = 0000 (midnight)
• 12:15 AM = 0:15 = 0015
• 12:30 AM = 0:30 = 0030

From 1:00 AM to 12:59 PM, the hours and minutes remain the same:

• 9:00 AM = 9:00 = 0900
• 10:30 AM = 10:30 = 1030
• 12:00 PM = 12:00 = 1200 (noon)

From 1:00 PM to 11:59 PM, add 12 hours:

• 1:15 PM = 13:15 = 1315
• 5:30 PM = 17:30 = 1730
• 11:59 PM = 23:59 = 2359

AM and PM

The abbreviations AM and PM are from Latin:

• AM: ante meridiem — before noon
• PM: post meridiem — after noon

Midnight: 00:00 and 24:00

In the 24-hour time notation, the day begins at midnight, 00:00. The notation 24:00 serves to refer to the end of a day. Physically, 24:00 of one day is the same time as 00:00 of the following day.
