What are the ways to convertbetween a.m and p.m.and 24-hour time?
When converting a.m./p.m. to 24-hour time for the hours between 12:00 a.m. and
12:59 a.m., just subtract 12 from the time. For instance, 12:45 a.m. minus 12 will equal
0045, and 12:59 a.m. minus 12 will equal 0059. Times between 1 a.m. and 12:59 p.m.
are a straight conversion, such as 9:00 a.m. equals 0900 and 11:00 a.m. equals 1100.
For the conversion between 1 p.m. and 11:59 p.m., add 12, such as 8:34 p.m. plus 12
equals 2034, and 11:59 p.m. plus 12 equals 2359 (also seen as 20:34 and 23:59).To convert in the opposite direction from the above, add 12 for the hours between
0000 (midnight) and 0059, such as 0034 plus 12 equals 12:34 a.m., and 0059 plus 12
equals 12:59 a.m. To convert from 0100 to 1159 and from 1200 to 12:29, there is a
one-to-one conversion, the former to a.m. and the latter to p.m.. For example, 0100
equals 1 a.m., 0345 equals 3:45 a.m., 1235 equals 12:35 p.m., and 1259 equals 12:59
p.m. To convert between 1300 and 2359, subtract 12, such as 1424 minus 12 equals
2:24 p.m., and 2359 minus 12 equals 11:59 p.m.How are local a.m./p.m.and 24-hour times convertedto Coordinated
Universal Time(UTC)?
When it comes to converting to specific times, Coordinated Universal Time (UTC) is a
“standard.” It is used for a variety of reasons, including certain scientific studies, such
398 as weather forecasting and astronomical data. The following lists several examples of
