1400 Military Time

1400 military time is 2:00 PM

1400 on a 24 hour clock is 2:00 PM. The hour pair reads 14, and 14 minus 12 leaves 2, which lands the time in the afternoon. The minute pair is 00, so the reading sits exactly on the hour. With a colon it is 14:00, and on a schedule it prints as four digits with nothing between them.

Counting from midnight makes the number less abstract. 0000 starts the day, 1300 ends the lunch hour, and 1400 is the fourteenth hour: 840 minutes after midnight, with 600 minutes left until the next one. Two in the afternoon is 60 minutes into the PM half of the clock, so about 8 percent of the afternoon block has passed.

The one thing 1400 is not is 14:00 AM. There is no such reading. The 24 hour code already names the afternoon, so the AM and PM tags have nothing left to say. Writing 1400 PM doubles the marker the same way, and both forms read as errors to anyone who works with logs.

It is also not a length of time. 1400 names a point in a day, while 14.00 names a duration of fourteen hours. On a timesheet the two sit close together and mean different things, which is where the trouble in the decimal section below starts.

Saying 1400 out loud, and how it gets written down

Spoken, 1400 is "fourteen hundred." On a formal log or a radio net it becomes "fourteen hundred hours," and on a noisy channel each digit is read on its own: one four zero zero. All three versions name the same instant, and none of them carries an AM or PM.

Writing has more rules than speaking, because the digits have to survive being copied. Four digits, no colon, no suffix. A schedule cell holds 1400, a hospital chart holds 14:00, and a radio log holds 1400Z when the stamp is UTC. Mixing the forms inside one document forces the reader to guess which convention is in force.

Morning times keep the leading zero. 0400 is 4:00 AM, and dropping the zero turns it into 400, which reads as four hundred hours to one person and as a typo to another. The zero costs one character and removes the guess, so it stays.

A header does the rest of the work. "Wed 11/04, local, 24 hour" tells the reader the date, the zone and the convention before the first row, and it costs one line on the page.

1400Z, and 1400 in every US time zone

A bare 1400 is a local reading. Add a Z and it becomes an instant the whole world agrees on, because 1400Z is 2:00 PM on the UTC clock that pilots, ships and astronomers use. The official US time service run by NIST and the Naval Observatory shows that clock live, and it is the place to check when a conversion has to be exact.

Converting is one subtraction in each direction. The US Naval Observatory zone table gives the standard offsets: Eastern is five hours behind UTC, Central six, Mountain seven, Pacific eight, Alaska nine, Hawaii-Aleutian ten.

Two rows deserve a second look. Hawaii sits ten hours behind, so 1400 HST lands on 0000 UTC the next day: it is two in the afternoon in Honolulu and midnight in Greenwich at the same moment. And each daylight zone sits one hour closer to UTC, so 1400 EDT is 1800 UTC rather than 1900.

Standard offsets are the ones in force right now. NIST lists the 2026 daylight period as March 8 through November 1, so from November 2 until March 2027 the whole country except Arizona, Hawaii and the territories is on standard time. A 1400 meeting in New York is 1900Z during that stretch.

Run the same stamp the other way and the digits drift twice a year. 1400Z reads 0900 in New York in November and 1000 in July. Same four digits, two local times, and that gap is why an invitation that drops the Z can move a meeting by five hours without anyone noticing until the empty call.

14.00 decimal hours, and why 14.30 is not 14:30

Payroll software stores time as decimal hours, and 1400 arrives as 14.00: fourteen full hours after midnight, and zero minutes that add nothing. The same instant in a spreadsheet cell reads 0.5833, because spreadsheet time is a fraction of a day and 14 / 24 = 0.5833. Both are the same instant in different clothing.

The trap starts with the minutes. Decimal hours convert base 60 into base 100 by dividing the minutes by 60, so half past two is 14.50 and not 14.30. A timesheet that writes 14.30 for a 2:30 PM punch has recorded 14 hours and 18 minutes, which is 12 minutes of unpaid time per entry, or $50 a week at a $50 hourly rate if it happens every day.

Read backward, the rule runs the other way: multiply the fraction by 60. 0.30 x 60 = 18 and 0.75 x 60 = 45. A decimal that will not land on a whole minute, such as 14.33, comes from a punch at 14:19.8, which is what a time clock records when someone clocks in twenty minutes late.

Which form belongs where is worth settling once. Clock readings go in the 1400 or 14:00 column, and durations go in the 14.00 column. The hour mark is the only place where the two agree, and every other minute value disagrees with the two digit reading of it.

Shift lengths that start at 1400

Shift length is where the four digit form earns its keep, provided the subtraction runs in minutes rather than in printed digits. Convert both ends to minutes after midnight, subtract, and the answer is the shift.

The 1400 to 2200 span is the classic second shift: 480 minutes, 8.00 decimal hours, and at $20 an hour it pays $160.00 gross. The 16.25 hour row pays $325.00 at the same rate, and that is the shape of a double or a storm call rather than an ordinary day.

Overnight rows need a date or a rule, because the printed digits go backward. From 1400 to 0200 a plain subtraction returns a negative, so a full day of 1,440 minutes gets added: 120 - 840 + 1440 = 720. Most payroll systems run that repair on their own and flag anything longer than 16 hours for review.

Punch rounding sits on top of the arithmetic. Many employers round to the nearest quarter hour, so a 1402 punch is paid from 1400 and a 1408 punch from 1415. Over a week the rounding can move a check a few dollars either way, which is why the rule lives in the employee handbook and not in a guess.

Where 1400 turns up during a workday

Hospital charts, lab requisitions, pharmacy labels and nursing notes use 24 hour times because 1400 cannot be mistaken for 0400 at a glance. The four digit form also sorts correctly as text, which matters when a list of medication times runs down a page in order.

Aviation weather reports stamp observations in UTC, so a METAR issued at 1400Z describes the same moment at every airport on earth, whatever the local clock says. Dispatch desks, rail timetables across most of Europe and shipping logs work the same way, and international standards documents write the same instant as 14:00:00.

Server logs are the quiet case. Most log formats store UTC, so a 2:00 PM incident in a Chicago office shows as 2000 in the log during standard time and 1900 during daylight time. Reading the log as if it were local repeats the zone mistake from the section above, just in a different costume.

Two people in different states can both write 1400 and mean two different instants. A schedule that crosses a zone boundary needs the offset written down even when every clock inside one building agrees, because the four digits name a position on a dial and not a place on the map.

Mistakes around 1400, and how to catch them

Writing 14:00 AM. The afternoon block runs from 1200 to 2359, so 1400 has no AM reading at all. If the entry must use AM and PM, write 2:00 PM and skip the code. If it must use the code, drop the suffix.

Reading 1400 as a decimal. A decimal-hours column that receives 1400 has been handed 1,400 hours, which is 58.3 days of work. The fix is a format check at entry: four digits with no decimal point go to the clock column, and anything with a point goes to the duration column.

Dropping the zone. 1400 on a local clock and 1400Z are different instants, five hours apart in New York in November and four hours apart in July. The Z costs nothing to type and answers the question before anyone has to ask it.

Losing the leading 1. Handwritten, 1400 can turn into 0400, which moves an appointment by ten hours and puts an afternoon visit at 4:00 AM. Printing the code, or reading it back digit by digit as one four zero zero, closes that hole.

Subtracting clock faces. From 1400 to 0200 the shift is 12 hours, not 2, and from 1400 to 0615 it is 16.25 hours. Minutes after midnight handle every case, including the ones that cross noon and midnight in the same shift.

None of these checks need software. A zone tag, a colon before the minutes, and one subtraction in minutes cover most of what goes wrong around this hour.
