Military time

How military time works

2000

20 hundred hours is 8:00 PM

The first 2 digits are the hour of a 24-hour day.

This means if it is after 12 noon, you need to subtract 12 hours to get the PM time.

The second 2 digits are the number of minutes past the hour.

Where it is exactly on the hour, hundred is spoken to denote 00, meaning zero minutes.

Numbers are often exaggerated so they can be heard better over a crackling radio.

For example, nine may be pronounced niner.

If there is a letter after the numbers, that tells the time zone.

I found this website very helpful: https://www.timeanddate.com/time/military-time.html

Here are some example times spoken in different ways, getting more complicated towards the bottom of the list.

Australian time spoken	AM/PM	24-hour clock	Military time	Military time spoken	Military time spoken casually
midnight	12 am	00:00	0000	zero hundred hours	If ending the day, twenty-four hundred hours
two o'clock in the morning	2 am	02:00	0200	zero two hundred hours	stupid o'clock!
six o'clock in the morning	6 am	06:00	0600	zero six hundred hours	oh six hundred
ten o'clock in the morning	10 am	10:00	1000	ten hundred hours (not zero ten hundred as there is no leading zero)	ten hundred
noon	12 pm	12:00	1200	twelve hundred hours	twelve hundred
six o'clock in the evening	6 pm	18:00	1800	eighteen hundred hours	eighteen hundred
nine o'clock at night	9 pm	21:00	2100	twenty-one hundred hours	twenty-one hundred
a quarter past nine at night	9:15 pm	21:15	2115	twenty-one fifteen hours	twenty-one one-fife
half past nine at night	9:30 pm	21:30	2130	twenty-one thirty hours	twenty-one tree-zero
a quarter to ten at night	9:45 pm	21:45	2145	twenty-one forty-five hours	twenty-one fower-fife
ten to ten at night	9:50 pm	21:50	21:50	twenty-one fifty hours	twenty-one fife-zero

So now you know what Sam is talking about when he keeps saying "hundred hours" in the Aussie Guards series.
