    We know that a day consists of 24hours. There are two different ways to calculate time – as 12 hours and as 24 hours. While using the 12 hour format, it is important to denote the time as p.m. or a.m. where A.M. stands for after Ante – meridian and is used before noon while P.M. stands for Post – Meridian and is used after noon.

    Thus, from midnight till noon – we use A.M. while using the 12 hour format.

    Whereas after noon till 11:59 in the night, we use P.M.

    The 24hour format does not require these mentions. After 12 in the noon, instead of using 1:00 p.m. we use 13hours, 2:00 p.m. as 14:00 hours and so on. A 24 hour clock starts at 1:00 in midnight and ends at 23:59 hours.

    The most simple way to convert 12 hours time format to 24 hours time format, follow these steps:

    1. If the time is between 12:00 A.M. – 11:59 A.M. — use the same time

    2. if the time is between 12:00 P.M. – 11:59 P.M. — add 12 to the time.

    for example- 1:00 P.M. = 1+12 = 13:00 hours

    6:30 P.M. = 6+12= 18:30 hours

    I hope this helps.
