AP style numbers, dates, times and percent: the complete cheat sheet

By MubarakUpdated 13 min read

Short answer:

AP style spells out one through nine and uses figures for 10 and up. The main exceptions: ages, percentages (5%), money ($5), times (9 a.m.), dates (Nov. 6), dimensions, speeds, temperatures and scores always take figures. Spell out any number that starts a sentence, unless it's a year.

AP style is the set of writing and editing rules published by The Associated Press in the AP Stylebook, the standard reference for U.S. news writing. This page covers only numbers, dates, times and places. For punctuation, titles and the rest, see the AP style guide. Rules reflect the 58th edition (2026). All examples are invented.

Numbers: the basic rule

RuleExample
One through nine: wordsthree reporters, nine days
10 and up: figures10 days, 47 votes, 1,200 readers
Start of a sentence: wordsForty-seven people voted.
...except years2026 was the hottest year on record.
Casual uses: wordsThanks a million. He walked a hundred yards.
Ordinals first to ninth: wordsfirst place, ninth grade
Ordinals 10th and up: figures10th anniversary, 21st century
Political and geographic ordinals: figures1st Ward, 9th Circuit, 5th District
Commas from 1,000 up1,200; 35,000
No commas in years, addresses, phone and room numbers2026; 1200 Main St.; Room 1012
Millions and billions: figure plus word3 million people, 1.5 billion users

If a sentence would start with a long number, rewrite it: "Voters cast 1,247 ballots" beats "One thousand two hundred forty-seven ballots were cast."

Distances follow the basic rule: "three miles," "12 miles."

Fractions and decimals

  • Spell out amounts under one, with hyphens: two-thirds, three-quarters.
  • Use figures for precise amounts over one: 2 1/2 (put a space between the whole number and the fraction).
  • Use figures for decimals: 0.6, 3.75. Use a zero before the point for numbers under one.

Dates and months in AP style

The months, with their AP forms when a date follows:

FebruaryFeb. 5AugustAug. 5
MarchMarch 5SeptemberSept. 5
AprilApril 5OctoberOct. 5

JuneJune 5DecemberDec. 5

A memory aid: the months of five letters or fewer (March, April, May, June, July) are never abbreviated.

Times: a.m., p.m., noon and midnight

RuleRightWrong
Figures, lowercase a.m. and p.m. with periods9 a.m., 7 p.m.9 AM, 7pm, 7 P.M.
No ":00" on the hour7 p.m.7:00 p.m.
Colon for minutes3:30 p.m.3.30 p.m.

Order: time, day, placeat 7 p.m. Tuesday at City Hallon Tuesday at City Hall at 7 p.m.
Time zones after the time3 p.m. EDT; noon Pacific timeEDT 3 p.m.

Midnight belongs to the day that is ending: a deadline of "midnight Friday" falls at the end of Friday. If readers could misread it, write "11:59 p.m. Friday."

Percent in AP style

AP announced on March 29, 2019, that the % sign is acceptable with a figure in most cases. Before that, AP wrote "5 percent." Any cheat sheet that still says "percent" with a figure is out of date.

RuleRightWrong
% with a figure, no space5%, 12.5%5 percent, 5 %
Decimals under 10.6%.6%
Repeat the sign in a range10% to 30%10 to 30%
Start of a sentence: spell out bothEighty percent of voters agreed.80% of voters agreed.
Casual uses: spell outa zero percent chancea 0% chance
Change between two percentagesrose 2 percentage points, from 4% to 6%rose 2%, from 4% to 6%

The last row is a meaning error, not just a style error. A rise from 4% to 6% is 2 percentage points, but a 50% increase in the rate. Say which you mean.

Money

RuleRightWrong
Dollar sign and figures$5, $1,500five dollars
No ".00"$5$5.00
Cents in words, figure for the amount5 cents$0.05, five cents
Millions and billions$3 million, $2.5 billion$3,000,000; $2.5 Billion
Up to two decimal places$7.55 million$7.5523 million
Repeat the unit in a range$5 million to $6 million$5 to $6 million
Casual usesa few dollars, a million reasons$ few

Ages

AP always uses figures for ages of people and animals.

States, cities and datelines

Since May 1, 2014, AP spells out state names in the body of stories. Use the abbreviations below only in datelines, photo captions, tables, lists, editor's notes and short party affiliations (D-Ill., R-Mont.). AP abbreviations are not postal codes. Use postal codes only in a full mailing address.

Cities that stand alone

These U.S. cities need no state in datelines or in text: Atlanta, Baltimore, Boston, Chicago, Cincinnati, Cleveland, Dallas, Denver, Detroit, Honolulu, Houston, Indianapolis, Las Vegas, Los Angeles, Miami, Milwaukee, Minneapolis, New Orleans, New York, Oklahoma City, Philadelphia, Phoenix, Pittsburgh, St. Louis, Salt Lake City, San Antonio, San Diego, San Francisco, Seattle and Washington.

Datelines

A dateline opens a news story with the city it was reported from: the city in capital letters, the state abbreviation if the city doesn't stand alone, then a dash.

DAYTON, Ohio โ€” The city council voted 5-4 on Thursday to ...
SPRINGFIELD, Ill. โ€” State lawmakers approved ...
DENVER โ€” A spring storm dropped 14 inches of snow ...

Inside the story, use the full state name: "Dayton, Ohio," "Springfield, Illinois."

Checking numbers in a draft

Numbers are the easiest AP errors to find by search. Before filing, search the draft for %, "percent," :00, "AM," "PM," every month name, st, nd, rd and th after figures, and two-letter state codes. If you write in WriteOrbit, the AI proofreading pass leaves issues as comments in the text and an editor can make AP fixes as tracked suggestions, but it has no dedicated AP rule engine, so this search pass still matters. See pricing for what the free plan includes.

FAQ

Does AP style spell out numbers?

Only one through nine, in general. AP style uses words for one through nine and figures for 10 and up. Ages, percentages, money, times, dates, dimensions, speeds, temperatures and scores always take figures, even under 10. Any number that starts a sentence is spelled out, except a year.

How do you write dates in AP style?

Use figures without st, nd, rd or th. With a specific date, abbreviate Jan., Feb., Aug., Sept., Oct., Nov. and Dec., and always spell out March, April, May, June and July: Nov. 6, 2026. With a month and year only, spell out the month and drop the comma: November 2026.

How does AP style write a.m. and p.m.?

Lowercase with periods, after a figure: 9 a.m., 3:30 p.m. Leave off ":00" on the hour. Use noon and midnight instead of 12 p.m. and 12 a.m. Avoid redundancies such as "10 a.m. this morning." For ranges, write 9 a.m. to 5 p.m., or 9-11 a.m. within the same half of the day.

Does AP style use the percent sign?

Yes, since 2019. AP style uses the % sign with a figure and no space in most cases: 5%, 0.6%. Spell out "percent" only in casual uses such as "a zero percent chance," and spell out both the number and the word at the start of a sentence: "Eighty percent of voters ..."

Does AP style abbreviate state names?

Not in the body of a story. Since 2014, AP spells out state names in text. It uses its own abbreviations, such as Calif. and Tenn., not postal codes, in datelines, photo captions, tables, lists and party affiliations. Alaska, Hawaii, Idaho, Iowa, Maine, Ohio, Texas and Utah are never abbreviated.
