2 pm
Habit, and convention. We all have to speak the same language if we're going to communicate. Personally, I prefer the 24 hour clock; so 1 PM is 13:00, and 9 PM is 21:00. Of course, I did spend 21 years in the Navy, and we used the 24-hour clock exclusively. But for talking to civilians in the US, you have to use the 12 hour clock with AM and PM.
5+12 is 17:00 in 24 hour clock
On a 24 hour clock, it's pm. On a twelve hour clock, it could be either.
12 hour clock's have am and pm. 24 hour clock's (military time) is 00:00 through 23:59. Midnight on a 12 hour clock is 12:00am, on a 24 hour clock is 00:00. So 23:59 would be 11:59pm.
2 PM on the 24 hour clock is 14:00.
A twelve hour clock has 1,2,3,4,5,6,7,8,9,10,11,12 and is the standard form time clock. A 24 hour clock has times starting at 1-12, but after it will start with 13 as 1 p.m. all the way to 24 or 00 as 12 midnight.
Add 12 to the number representing hours, from 1:00 pm to just before midnight.
AM is 00:00 to 11:59. PM is 12:00 to 23:59.
16.30PM
It is 10:00 PM (Post Meridiem, meaning "after noon" in the 12-hour clock).Or 22:00 (in the 24-hour clock).
16:00 is 4pm on a 24 hour clock.
It depends upon whether you use a 12 hour clock with am and pm, or a 24 hour clock. The 12 hour clock has just 1 set of 12 consecutive numbers, 1 2 3 4 5 6 7 8 9 10 11 12. The 24 hour clock has 13 sets of 12 consecutive numbers.
8.30 am 8 and 30 mins (am) + 6 = 14 and 30 mins on the 24 hour clock or 2 and 30 mins (pm) on the 12 hour clock.
