The expert horologists at Chelsea Clock — America’s premier clockmaker since 1897 — are sometimes requested in regards to the variations between navy time, and what most of our prospects check with as commonplace or “civilian” time. When boiled all the way down to the nitty-gritty, what individuals actually wish to know is why does the U.S. navy function on a 24-hour clock?
The reply right here is sort of easy: The U.S. navy (and all world militaries, for that matter) operates on a 24-hour clock for pure effectivity. There are 24 hours in a day, as you’re properly conscious. By demarcating the hours inside a 24-hour timeframe (or day) with a particular quantity, starting from 0100 (1) to 2400 (24), any confusion that may come up between AM and PM when relying upon an ordinary civilian time is eradicated. As an illustration, 1:00 AM in navy time is expressed as 0100 (zero 100 hours), whereas 1:00 PM can be represented as 1300 (13 hundred hours). If the operation begins at 5, you’d wish to make certain your commanders and troops perceive that it begins at 5 within the morning (0500 navy time), and never 5:00 PM.
Army and commonplace time use minutes and seconds in exactly the identical method, though navy time isn’t written with a colon. For instance, 1:05 PM can be expressed as 1305 hours. When changing from commonplace civilian time to navy time or vice versa, the minutes and seconds don’t change.
If you wish to know say 0000 in navy time, or midnight, which might be written as both 2400 or 0000, say “twenty-four hundred hours,” though you’ll usually see it printed as 0000, as this hour is taken into account the start line of a brand new day.
Army time is a exact methodology for timekeeping utilized by the navy, in addition to loads of completely different emergency service businesses and personnel, together with legislation enforcement officers, firefighters, emergency medical professionals and others.
