Converting
Military Time
In
daily life, most of us use the typical 12 hour clock to tell time. In using this method, that means that we are
also required to say and use AM or PM.
This causes multiple problems such as typos in emails,
mis-understandings in conversations, and the dreaded alarm clock. How many of us have used our phones and
accidentally set it to go off at 7:00 PM instead of AM? Never fear, there is a solution to the AM-PM
fiasco, which is to use the 24 hour clock that is used in the military. Never heard of the 24 hour clock before? No problem, it's fairly simple to understand.
The
first part of the 12 hours is easy, because you already know it! It starts at 0000 and makes it way up to
2400. The clock starts at midnight,
which is officially the beginning of the day.
The end of the day is also at midnight, signalling the end of the
previous day and the start of the next.
The trick is not to think of midnight as being the end of the day
because it may mess up the thinking process with the numbers.
When
using a 24 hour clock, the numbers are always in thousands. For instance, midnight is 0000, signalling it
is the beginning of the day. You would
read it as “it's zero hundred hours.”
Where we would say, “it's one o-clock,” the military would say that it
is “ thirteen hundred hours” (1300).
This may seem extremely confusing right now, but will get clearer as we
go through the entire process step by step.
At the end, you'll be able to see how much simpler and clearer 24 hour
time telling is.
Now
that we've learned a few things about how to read it, let's learn now to tell
it. It is best expressed through a
chart:
