31 minutes past 9
9:00 pm on a 12-hour clock is equivalent to 21:00 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.
If you're asking what time is 0900 on a 24 hour clock it would be 9 am. or 2x450 = 900
45 is an odd number. It is the result of multiplying 5 by 9. In a 24-hour clock, 45 minutes is three-quarters of an hour.
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.
The military normally use the 24 hour clock, so 9:30am would be 0900 hours.
Well, when it's five minutes past nine in the morning on a 24-hour clock, we simply write it as 09:05. It's just like regular time, but we keep counting up past 12 instead of starting over. Just a little adjustment, and you've got the time all set on your clock.
add 41490 then divide by 150Alternatively:-101010 => 10 T0 10 = 9:50 on the 24 hour clock
+9 or -3. Take your pick.
2100 in Tel Aviv is equivalent to 9:00 PM in the 24-hour clock format.
12 divides into 33 twice (2 x 12 = 24) leaving a remainder of 9. In clock arithmetic you are focusing on the remainder after the number reaches a certain value (the modulus) or a multiple of the modulus. For a 12 hour clock the modulus is 12 and the calculation is written as follows :- 3 x 11 = 33 Ξ 9 (mod 12)
9 plus 4 equals 1 in the 12 hour clock. If you start at 9am in the morning, and add 4 hours too the 9, you get an answer of 1 if you count using the 12 hour clock.
