How to Write the Date in English

British vs. American Date Formats

English uses two main date format systems depending on region. British English follows day-month-year order, while American English uses month-day-year order. Understanding both formats prevents confusion in international communication.

British English Date Format

In British English (used in UK, Australia, New Zealand, and most Commonwealth countries), the day appears first, followed by the month, then the year. Common British formats for 6 September 2024:

• 6 Sept
• 6 September
• 6 September 2024
• 6th September 2024
• the 6th of September 2024
• Saturday, 6 September 2024

Important rules:

• When using “the” and “of,” both must be included (not just one)
• Commas are optional after the year in British English
• Day names come before the date, separated by comma or using “the…of” construction

American English Date Format

In American English, the month comes first, followed by the day, then the year. This order differs significantly from British usage and causes frequent confusion. Common American formats for September 6, 2024:

• Sept 6
• September 6
• September 6, 2024
• Monday, September 6, 2024

Important rules:

• Comma required after the day when year is included
• Comma required after year when sentence continues
• Ordinal indicators (st, nd, rd, th) less common in American writing
• Day names come before the date, always followed by comma

Writing Dates in Numbers

Numeric date formats present the greatest source of confusion between British and American English. The order of elements changes completely, potentially causing misunderstandings.

British Numeric Format (Day/Month/Year)

• 6/9/24 or 6-9-24 or 6.9.24
• 06/09/2024 or 06-09-2024 or 06.09.2024
• 6 Sept 2024 or 6-Sept-24

American Numeric Format (Month/Day/Year)

• 9/6/24 or 9-6-24 or 9.6.24
• 09/06/2024 or 09-06-2024 or 09.06.2024
• Sept 6, 2024 or Sept. 6, 2024

Common separators: Forward slash (/), hyphen (-), or period (.) — all acceptable, but slash most common.

The Confusion Problem

International Standard Format (ISO 8601)

To eliminate confusion in international contexts, ISO 8601 standard recommends Year-Month-Day format with hyphens: YYYY-MM-DD. Advantages of ISO format:

• Completely unambiguous across all regions
• Sorts chronologically when filed alphabetically
• Widely used in computing and international business
• Common in Asia (China, Japan, Korea, Taiwan)

Formal vs. Informal Date Writing

The level of formality affects which date format to use. Business letters, academic papers, and official documents require different formatting than personal emails or casual notes.

Formal Date Writing

Formal contexts include: Business correspondence, legal documents, academic papers, official reports, job applications, formal invitations. Formal format requirements:

• Always spell out the month completely (never abbreviate)
• Include the full four-digit year
• Avoid purely numeric formats
• Use complete day names when including day of week

Formal examples:

• British: 13 April 2024 or 13th April 2024
• American: April 13, 2024
• With day: Monday, 13 April 2024 (British) or Monday, April 13, 2024 (American)

Informal Date Writing

Informal contexts include: Personal emails, text messages, casual notes, diary entries, social media posts. Informal format options:

• Abbreviate months: Jan, Feb, Mar, Apr, Jul, Aug, Sept, Oct, Nov, Dec
• Use two-digit years: 24 instead of 2024
• Numeric formats acceptable: 13/04/24 or 04/13/24
• Omit day of week or year when context clear

Informal examples:

• 13 Apr 24 or Apr 13 ’24
• 13/04/2024 or 04/13/2024
• Saturday the 13th

Using Days of the Week with Dates

When including the day of the week, specific punctuation rules apply depending on whether using British or American format. British English with day names:

• Saturday, 13 April 2024 (comma after day name)
• Saturday the 13th of April 2024 (no comma with “the…of”)

American English with day names:

• Saturday, April 13, 2024 (comma after day name AND after day number)
• On Saturday, April 13, 2024, the meeting begins. (comma after year when sentence continues)

Comma Rules for Dates

Comma placement varies significantly between British and American English. Incorrect comma usage is one of the most common date-writing errors.

American English Comma Rules

• Comma required after day when year included: April 13, 2024
• Comma required after year when sentence continues: On April 13, 2024, the event begins.
• Comma required after day name: Monday, April 13, 2024
• Both commas must appear together (never just one)

British English Comma Rules

• Commas generally not used in dates
• Comma optional after day name: Saturday, 13 April 2024 or Saturday 13 April 2024
• Comma acceptable but unnecessary after year
• Using “the…of” construction typically omits commas

Ordinal vs. Cardinal Numbers in Dates

Understanding when to use ordinal numbers (1st, 2nd, 3rd) versus cardinal numbers (1, 2, 3) prevents common errors in date writing.

Written Dates: Cardinal Numbers Preferred

In modern English writing, cardinal numbers are standard in month-day format, though ordinal indicators are optional in British English.

• American standard: April 13, 2024 (cardinal number, no ordinal indicator)
• British options: 13 April 2024 (cardinal) or 13th April 2024 (ordinal)
• Both acceptable: Either style works in British English; cardinal slightly more modern

Spoken Dates: Always Ordinal

When speaking dates aloud, always pronounce them as ordinal numbers, regardless of how they appear in writing.

Using “The” and “Of”

The construction “the [ordinal] of [month]” requires both words—using only one creates grammatical error.

• ✓ the 6th of September
• ✗ 6th of September (missing “the”)
• ✗ the 6th September (missing “of”)

Writing Years, Decades, and Centuries

Years in Numbers

Years should always be written as numerals in the middle or end of sentences. Only at sentence beginnings should years be spelled out as words.

• ✓ The year 2024 brought significant changes.
• ✓ Twenty twenty-four brought significant changes. (sentence beginning)
• ✗ The year two thousand twenty-four brought changes. (too wordy mid-sentence)

Speaking Years Aloud

Pre-2000 years: Split into two pairs of digits.

• 1985 = “nineteen eighty-five”
• 1776 = “seventeen seventy-six”
• 1492 = “fourteen ninety-two”

2000-2009: Say “two thousand and [number].”

• 2001 = “two thousand and one”
• 2009 = “two thousand and nine”

2010-present: Either “two thousand and [number]” or “twenty [number].”

• 2015 = “two thousand fifteen” or “twenty fifteen”
• 2024 = “two thousand twenty-four” or “twenty twenty-four”

Writing Decades

Decades can be written as numbers with apostrophe before them or spelled out as words. Avoid apostrophe between number and “s.”

• ✓ the ’90s (apostrophe replaces century digits)
• ✓ the 1990s (full four digits, no apostrophe)
• ✓ the nineties (spelled out)
• ✗ the 1990’s (apostrophe incorrectly shows possession)
• ✗ the 90’s (missing apostrophe before 90)

Writing Centuries

Centuries are plural nouns, not possessives. Write them without apostrophe before “s,” and lowercase unless part of historical period name.

• ✓ the 1800s
• ✓ the nineteenth century
• ✓ the 21st century
• ✗ the 1800’s (incorrect apostrophe)
• ✗ the Nineteenth Century (unnecessary capitals)

Month Abbreviations

Most months can be abbreviated in informal writing, but some abbreviation rules require attention.

Month	Standard Abbreviation	Alternative
January	Jan	Jan.
February	Feb	Feb.
March	Mar	Mar.
April	Apr	Apr.
May	May	—
June	June	Jun
July	July	Jul
August	Aug	Aug.
September	Sept	Sep
October	Oct	Oct.
November	Nov	Nov.
December	Dec	Dec.

Key points:

• May never abbreviated (too short)
• June and July often written in full (only 4 letters)
• September can be Sept or Sep (both acceptable)
• Periods after abbreviations optional but be consistent
• Never abbreviate in formal writing
• Always capitalize month names and abbreviations

Common Mistakes to Avoid

• Mixing formats in same document: Choose British or American format and remain consistent throughout
• Forgetting commas in American dates: Must include comma after day AND after year
• Using apostrophes incorrectly: 1990’s is wrong; 1990s or ’90s correct
• Starting sentences with numerals: Spell out years at sentence beginnings
• Incomplete “the…of” construction: Must include both “the” and “of” or neither
• Lowercase month names: Always capitalize months in English
• Confusing British/American numeric dates: 03/04/2024 means different dates in different regions
