1 MILITARY TIME THE 24 HOUR CLOCK

2 THE TWENTY-FOUR-HOUR CLOCK THE MILITARY SERVICES AND CIVILIANS USE DIFFERENT METHODS OF EXPRESSING TIME. ALL CADETS SHOULD LEARN THIS METHOD, CALLED MILITARY TIME OR THE TWENTY-FOUR-HOUR CLOCK.

3 HOW WE EXPRESS TIME u IN CIVILIAN LIFE, WE CONVEY TIME TO ONE ANOTHER BY USING: A.M.ORP.M.

4 WHEN WE SAY OR WRITE 8 A.M., WE MEAN.. EIGHT O’CLOCK IN THE MORNING WE WRITE THIS AS.. 8 A.M.

5 “A.M.” MEANS.. ANTE MERIDIEM OR BEFORE NOON (Or before the middle of the day)

6 WHEN WE SAY OR WRITE 8 P.M., WE MEAN.. EIGHT O’ CLOCK AT NIGHT WE WRITE THIS AS.. 8 P.M.

7 PM MEANS.. POST MERIDIEM OR AFTER NOON (Or after the middle of the day)

8 TO GIVE THE EXACT TIMES u WE ATTACH THE MINUTES AFTER THE HOUR, SUCH AS.. 8:45 A.M. WHICH MEANS: 45 MINUTES AFTER EIGHT O’CLOCK IN THE MORNING, OR..

9 8:45 P.M. WHICH MEANS: 45 MINUTES AFTER EIGHT O’CLOCK AT NIGHT

10 WE GIVE SPECIAL NAMES TO 12 A.M. AND 12 P.M. u WE CALL 12 A.M. MIDNIGHT u AND WE CALL 12 P.M. NOON

11 THIS SYSTEM WORKS FINE IN CIVILIAN LIFE IN THE MILITARY, SUCH A SYSTEM WOULD BE CONFUSING AND CAUSE MANY PROBLEMS. THE MILITARY WORKS ALL OVER THE WORLD, IN MANY DIFFERENT TIME ZONES.

12 WE CAN NOT AFFORD MISTAKES IN COMMUNICATING THE CORRECT TIME.

13 NAVY COMMUNICATIONS ARE BY MESSAGE OR RADIO TIMES SENT BY THIS METHOD COULD BE GARBLED OR HAVE STATIC INTERFERENCE OR NOT BE UNDERSTOOD BECAUSE OF BATTLE NOISES.

14 NAVY COMMUNICATIONS ARE BY MESSAGE OR RADIO u TYPED AND WRITTEN MESSAGES CAN ALSO HAVE COMMON MISTAKES IN TIME.

15 RESULTS! BATTLES AND LIVES COULD BE LOST BECAUSE AN IMPORTANT EVENT WAS NOT ON TIME!

16 TIME IS ALSO ESSENTIAL TO NAVIGATION u THE SHIP’S NAVIGATOR MUST KEEP ACCURATE TIME TO FIX THE SHIP’S POSITION.

17 WATCH AND LOG ENTRIES u ALMOST EVERY RECORD OF ANY TYPE ON A SHIP IS RECORDED WITH ACCURATE TIMES, 24 HOURS A DAY.

18 MILITARY TIME THE MILITARY MUST HAVE A SYSTEM THAT CAN NOT BE MISUNDERSTOOD!!

19 THIS MEANS HAVING AN EXACT TIME FOR EVERY HOUR AND MINUTE OF THE DAY.

20 EXPLAINING THE 24-HOUR- CLOCK IN THE MILITARY TIME SYSTEM, WE DO AWAY WITH : A.M.ANDP.M.

21 YOU WILL RECOGNIZE DAY OR NIGHT BY THE HOUR ITSELF. EIGHT O’CLOCK IN THE MORNING CAN NOT BE CONFUSED WITH EIGHT O’CLOCK AT NIGHT! WE ALSO ELIMINATE USING THE EXPRESSION “O’CLOCK.”

22 HOW IT WORKS! EACH HOUR AND EACH MINUTE OF THE DAY HAS ITS OWN NUMBER. EACH DAY STARTS AT A FRACTION OF A SECOND AFTER MIDNIGHT. THIS TIME IS CALLED : 0000

23 ONE O’ CLOCK IN THE MORNING IS 0100,PRONOUNCED ZERO ONE HUNDRED.

24 TWO O’CLOCK IN THE MORNING IS 0200,PRONOUNCED ZERO TWO HUNDRED

25 THE MORNING HOURS CONTINUE AS FOLLOWS: 3 O’CLOCK 0300 ZERO THREE HUNDRED 4 O’CLOCK 0400 ZERO FOUR HUNDRED 5 O’CLOCK 0500 ZERO FIVE HUNDRED AND SO ON UNTIL TEN O’CLOCK IN THE MORNING, WHICH IS PRONOUNCED TEN HUNDRED.

26 ELEVEN O’CLOCK IS 1100 OR ELEVEN HUNDRED AND NOON IS 1200 PRONOUNCED TWELVE HUNDRED.

27 THE AFTERNOON HOURS THE HOUR FOLLOWING 1200 OR NOON IS: 1300 IN CIVILIAN TIME THAT WAS 1:00 PM IN MILITARY TIME IT IS THIRTEEN HUNDRED

28 AFTERNOON TIMES CONTINUE: 2 PM OR FOURTEEN HUNDRED 3 PM OR FIFTEEN HUNDRED 4 PM OR SIXTEEN HUNDRED 5 PM OR SEVENTEEN HUNDRED THIS SEQUENCE CONTINUES UNTIL ELEVEN O’CLOCK AT NIGHT WHICH IS : 2300

29 THE DAY ENDS AT MIDNIGHT WHICH THE MILITARY CALLS: 2400OR0000 THE CLOCK TURNS OVER AT 2400 AND BECOMES 0000

30 HOURS ON THE MILITARY CLOCK 0000 OR 2400 (MIDNIGHT) O’CLOCK IN THE MORNING O’CLOCK IN THE MORNING O’CLOCK IN THE MORNING O’CLOCK IN THE MORNING O’CLOCK IN THE MORNING O’CLOCK IN THE MORNING

31 O’CLOCK IN THE MORNING O’CLOCK IN THE MORNING O’CLOCK IN THE MORNING O’CLOCK IN THE MORNING O’CLOCK IN THE MORNING O’CLOCK NOON O’CLOCK IN THE AFTERNOON O’CLOCK IN THE AFTERNOON O’CLOCK IN THE AFTERNOON

32 O’CLOCK IN THE AFTERNOON O’CLOCK IN THE AFTERNOON O’CLOCK IN THE EVENING O’CLOCK IN THE EVENING O’CLOCK IN THE EVENING O’CLOCK IN THE EVENING O’CLOCK IN THE EVENING O’CLOCK IN THE EVENING

33 PUTTING THE MINUTES INTO THE TIME MINUTES ARE USED THE SAME WAY AS THEY WERE WITH CIVILIAN TIME: 45 MINUTES AFTER EIGHT IN THE MORNING WOULD BE: 0845

34 10 MINUTES AFTER ELEVEN IN THE MORNING WOULD READ: MINUTES AFTER ONE IN THE AFTERNOON WOULD READ: MINUTES BEFORE MIDNIGHT WOULD READ: 2350

35 FIRST MINUTES OF THE DAY REMEMBER - MIDNIGHT IS 2400 OR 0000 ONE MINUTE AFTER MIDNIGHT IS 0001 TEN MINUTES AFTER MIDNIGHT IS 0010

36 A HINT FOR REMEMBERING MILITARY TIME AFTERNOON TIMES CAN BE CONVERTED BY ADDING 12 EXAMPLE 3:15 P.M. ADD 3: = 1515

37 TIMES BEFORE NOON ARE JUST AS THEY APPEAR 7:OO A.M. BECOMES :25 A.M. BECOMES 0825

39 2:05 IN THE AFTERNOON ANSWER:1405 9:20 AT NIGHT ANSWER:2120

40 0NE MINUTE BEFORE MIDNIGHT ANSWER:2359 ONE MINUTE AFTER MIDNIGHT ANSWER:0001
