In American English, dates are commonly written as Month Day, Year, such as “June 17, 2026.” In British English, dates are commonly written as Day Month Year, such as “17 June 2026.” Writing the month in words helps avoid confusion when numeric dates like 06/07/2026 can mean different dates in different countries.
American English Date Format in Words
When writing dates in words in American English, the usual order is the month, followed by the day, and then the year. A comma is typically placed between the day and the year.
- Format: Month Day, Year
- Example: June 17, 2026
- Another Example: December 25, 2026
In casual writing, you might sometimes see an ordinal suffix (like "th" or "st") added to the day, for example, "June 17th, 2026." However, many formal style guides in American English prefer to omit the ordinal suffix in written dates when the year is present, using "June 17, 2026" instead.
British English Date Format in Words
British English usually places the day before the month, followed by the year. Often, no comma is used to separate the day and year, especially in formal writing.
- Format: Day Month Year
- Example: 17 June 2026
- Another Example: 25 December 2026
While "17th June 2026" can be seen in some contexts, "17 June 2026" is commonly preferred in formal British writing, especially in official documents or publications.
Why Numeric Dates Can Be Confusing
One of the main reasons to write dates in words, or at least spell out the month, is to prevent ambiguity caused by different numeric date formats. The same sequence of numbers can mean entirely different dates depending on whether you are using an American or British interpretation.
- Numeric Date: 06/07/2026
- American English interpretation: June 7, 2026 (Month/Day/Year)
- British English interpretation: 6 July 2026 (Day/Month/Year)
- Numeric Date: 01/02/2026
- American English interpretation: January 2, 2026
- British English interpretation: 1 February 2026
Spelling out the month, such as "June 7, 2026" or "7 June 2026," makes the date unambiguously clear.
Month Names, Day Numbers, and Ordinal Forms
When writing dates in words, the month name is always fully spelled out. The day is typically written as a cardinal number (e.g., 17, 5, 25) in formal written dates, but ordinal forms are common in spoken English.
- Written Date (American): June 17, 2026
- Spoken Date (American): June seventeenth, twenty twenty-six
- Written Date (British): 17 June 2026
- Spoken Date (British): the seventeenth of June, twenty twenty-six
Notice that in British spoken English, "the" often precedes the day, and "of" may appear before the month, though this varies in informal speech.
When to Use Commas
Comma usage in dates primarily differs between American and British English when the year is included:
- American English: A comma is usually placed between the day and the year.
- Example: March 5, 1998
- British English: Commas are generally omitted in the Day Month Year format.
- Example: 5 March 1998
When only the month and year are given, no comma is typically used in either style (e.g., "June 2026").
Date of Birth Examples
When writing a date of birth in words, follow the conventions of the specific English dialect you are using or the document's required style.
- American English: Date of birth: March 5, 1998
- British English: Date of birth: 5 March 1998
Formal Document Examples
For legal, official, or academic documents, clarity is paramount. Always check the specific style guide or instructions provided by the institution or form. While these often prefer written-out months to avoid ambiguity, the exact format (American or British) should be consistent throughout the document.
- For a form requiring American English: "I certify that my date of birth is July 4, 1985."
- For a form requiring British English: "I certify that my date of birth is 4 July 1985."
Comparison Table: American vs. British Date Formats
| Numeric Date or Example | American English | British English | What to Notice |
|---|---|---|---|
| June 17, 2026 | June 17, 2026 | 17 June 2026 | Order of month/day and comma use. |
| 06/07/2026 | June 7, 2026 | 6 July 2026 | Ambiguity: Month/Day vs. Day/Month. |
| 01/02/2026 | January 2, 2026 | 1 February 2026 | Ambiguity: Month/Day vs. Day/Month. |
| 03/05/1998 | March 5, 1998 | 5 March 1998 | Ambiguity and different punctuation. |
| December 25, 2026 | December 25, 2026 | 25 December 2026 | Order of month/day and comma use. |
Common Mistakes to Avoid
- Mixing Formats: Switching between American and British formats within the same document can cause confusion. Choose one and stick to it.
- Incorrect Punctuation: Forgetting the comma in American English (Month Day Year) or adding an unnecessary comma in British English (Day, Month Year).
- Ambiguous Numeric Dates: Using only numbers (e.g., 04/05/2023) when the context doesn't clarify the intended format. Always spell out the month for clarity if there's any doubt.
- Incorrect Ordinal Usage: While "June 17th" is common in speech, some formal American style guides omit the "th" in written dates like "June 17, 2026." In British English, "17 June" is often preferred over "17th June" in formal writing.

Frequently Asked Questions (FAQs)
1. What is the difference between American and British date format?
The primary difference is the order of the day and month. American English commonly uses Month Day, Year (e.g., June 17, 2026), while British English commonly uses Day Month Year (e.g., 17 June 2026). Punctuation also differs, with American English usually including a comma before the year, which British English often omits.
2. How do you write a date in words?
To write a date in words, you spell out the month name and use numerals for the day and year. For example, in American English, you write "July 4, 1776." In British English, you write "4 July 1776." The specific format depends on whether you are following American or British English conventions.
3. Should I write “17 June 2026” or “17th June 2026”?
In British English, "17 June 2026" is generally preferred in formal writing and many official documents. While "17th June 2026" is sometimes seen, especially in less formal contexts or speech, omitting the "th" is often considered more standard for written dates in British English.
4. Is “June 17th, 2026” correct?
In American English, "June 17th, 2026" is common in casual writing and speech. However, many formal style guides recommend omitting the ordinal suffix ("th," "st," "nd," "rd") when the year is present, preferring "June 17, 2026." It depends on the formality and the specific style guide being followed.
5. How should I write my date of birth in words?
When writing your date of birth in words, follow the date format appropriate for the document or audience. If it's for an American context, use "Month Day, Year" (e.g., March 5, 1998). If it's for a British context, use "Day Month Year" (e.g., 5 March 1998). Always spell out the month to ensure clarity.
Practical Summary
Understanding the differences between American and British English date formats is crucial for clear communication. Remember that American English typically places the month first (Month Day, Year, with a comma), while British English places the day first (Day Month Year, often without a comma). When in doubt, spelling out the month is always the safest way to avoid confusion, especially with numeric dates that can be interpreted differently. Always consider your audience and the context to choose the appropriate style.
