We typically usage 12-hour clock device. The hour hand also of the clock goes round the dial twice a day (24 hours). Some departments favor railways, Airlines, and so on use 24-hour clock mechanism because they carry out not use a.m. and also p.m. times.

In a 24-hour clock system, we expush time in 4 digits. The first two digits represent hrs and the last 2 digits reexisting the minutes.

On the dial tright here are two concentric circles. The inner circle has 1 to 12 numbers while the external circle has 13 to 24 numbers.

In a 24-hour clock mechanism, we start counting the moment from midnight. Let us understand 24-hour system by considering some examples.

(i) 12 midnight is deprovided by 24 00 hrs or 00 00 hour.

(ii) 12 noon is dedetailed by 12 00 hrs.

(iii) 6 in the morning is delisted by 06 00 hrs.

(iv) 10:25 in the evening is delisted by 22 25 hours. (10:25 + 12:00)(v) 7:15 in the evening is delisted by 19 15 hrs. (7:15 + 12:00)

From the over examples, we deserve to conclude that in between 12 midnight and also 12 noon the 24-hour clock time is exact same.

For instance, 10 40 hrs = 10:40 a.m., 08 20 hrs = 8:20 a.m., 11 30 hrs = 11:30 a.m.

But between 12 noon and 12 midnight to transform the 24-hour clock time into 12-hour clock time, we subtract 12 from the 24-hour time.

For example, 19:30 hrs = 19:30 – 12:00 = 7:30 p.m.

Similarly, to convert the 12-hour clock time right into 24-hour clock time in between 12 noon and also 12 midnight, we add 12.

For example, 11:30 p.m. = 11:30 + 12:00 = 23:30 hours.

Because of this, the time which is shown by the inner circle is the moment before noon and that shown by the outer circle is the time after noon.

These are some more examples:After midnight          00:10 a.m. is displayed as 00:10                              02:45 a.m. is displayed as 02:45                              10:48 a.m. is shown as 10:48                              02:45 p.m. is presented as 14:45                              10:48 p.m. is displayed as 22:48

We recognize just how to use a.m. and p.m. to represent the moment of the day in 12-hour clock. We recognize that a.m. is offered to expush time between 12 o’clock mid night to 12 o’clock noon and p.m. is provided to express time between 12 o’clock noon to 12 o’clock midnight.

In 24-hour clock time, we express time in 4 digits. The first two digits from left repremainder hrs and also the last 2 digits recurrent the minutes.

So, to expush time for a.m., we simply create the time without separating hrs and minutes.

For instance 7:45 am is composed as 0745 hours.

To expush time for p.m. we add 12 to the hours and then write hours and also minutes without separating them. For example 6:30 p.m. is written as (6 + 12), 1830 hours.

24-Hour Clock Time Format:

The hour hand of the clock goes round the clock twice a day that suggests 24 hours. 24-hour clock time does not have actually a.m. or p.m. In 24-hour clock system, we express time in 4 digits. The first 2 digits represent hrs and also the last two digits recurrent the minutes. There are no dots to sepaprice hrs and also minutes. The time starts at 0000 hours or 2400 hrs which is 12 midnight.

In a 24-hour clock system, we begin counting the moment from midnight. Let us understand 24-hour system by considering some examples.

1. Converting 12-Hour Clock to 24-Hour Clock Time Format:

12-Hour Time to 24-Hour Time Conversion Table

 12-Hour Clock Time 24-Hour Clock Time 12 midnight 0000 hrs or 2400 hours 1 a.m. 0100 hours 2 a.m. 0200 hours 3 a.m. 0300 hours 4 a.m. 0400 hours 5 a.m. 0500 hours 6 a.m. 0600 hours 7 a.m. 0700 hours 8 a.m. 0800 hours 9 a.m. 0900 hours 10 a.m. 1000 hours 11 a.m. 1100 hours

 12 noon 1200 hours 1 p.m. 1300 hours 2 p.m. 1400 hours 3 p.m. 1500 hours 4 p.m. 1600 hours 5 p.m. 1700 hours 6 p.m. 1800 hours 7 p.m. 1900 hours 8 p.m. 2000 hours 9 p.m. 2100 hours 10 p.m. 2200 hours 11 p.m. 2300 hours

I. For the first hour of the day (12 Midnight to 12:59 a.m.), subtract 12 hours

For example:

(i) 12 Midnight = 0000 hours

(ii) 12:05 a.m. = 0005 hours

(iii) 12:40 a.m. = 0040 hours

II. From 1:00 a.m. to 12:59 p.m., no adjust.

For example:

(i) 6:40 a.m. = 0640 hours

(ii) 12:30 p.m. = 1230 hours

(iii) 10:45 a.m. = 1045 hours

III. From 1:00 p.m. to 11:59 p.m., add 12 hours

(i) 3:45 p.m. = 1545 hrs (3:45 + 12)

(ii) 6:20 p.m. = 1820 hrs (6:20 + 12)

(iii) 08:55 p.m. = 2055 hrs (8:55 + 12)

2. Converting 24-Hour Clock to a.m. or p.m.

I. For the initially hour of the day (0000to 0059), include 12 hours to make it a.m.

For example:

(i) 0001 hrs = 12:01 a.m.

(ii) 0048 hrs = 12:48 a.m.

II. From 0100 hours to 1159 hrs,simply include a.m. after the hrs.

For example:

(i) 0225 hrs = 2:25 a.m.

(ii) 1150 hours = 11:50 a.m.

III. From 1200 hrs to 12 hours 59, simply include p.m. after thehrs.

For example:

(i) 1235 hrs = 12:35 p.m.

(ii) 1205 hours = 12:05 p.m.

IV. From 1300 hours to 23 hrs 59, subtract 12 hours to make itp.m.

For example:

(i) 1355 hrs = 1:55 p.m.

(ii) 1725 hours = 5:25 p.m.
