Dates are a daily necessity, but the rules change depending on where you are. A simple date like 01/02 can lead to missed meetings or travel blunders if you aren’t sure which format is being used.
This guide breaks down the differences between American English, British English, and American Military date formats, how to say years out loud, and the proper use of prepositions.
American vs. British date formats
The most significant difference in telling the date lies in the order of the day and month. Misunderstanding this can lead to confusion, especially when using all-numerical formats (like 01/02/2025).
American English (Month-Day-Year)
In the United States, the month almost always comes first.
- Written: July 4, 2024 or July 4th, 2024
- Spoken: “July fourth, twenty twenty-four”
- Numerical: 07/04/2024
Military date format: The hybrid standard
While US civilians use Month-Day-Year, the US military follows a specific format that more closely resembles the international style. This is designed for maximum clarity in high-stakes communication where a misinterpreted date could have serious consequences. As a veteran of the United States Army, I can tell you that you will certainly be flagged for using the wrong format on an official document.
How to write a military date
In a formal military context, the date is written as Day Month Year without any commas.
- Example: 24 December 2025
- Abbreviated Example: 24 DEC 25
Key features of military dates
- No commas: Unlike the standard American format (July 4, 2024), the military format removes punctuation to keep the text clean.
- Three-letter months: Months are almost always abbreviated to three letters in all-caps (e.g., JAN, FEB, MAR).
- Zero padding: For days 1 through 9, a leading zero is often used (e.g., 04 JUL 2024) to ensure the date always occupies the same amount of space on a form.
Expert tip: The US military uses this “Day-Month-Year” format because it eliminates the confusion that happens when a “01/02” could mean either January 2nd or February 1st. It is a “Gold Standard” for clarity in international operations.
If you’re looking to practice your formatting and stay organized, using a Legend Planner is a great way to track deadlines using the military or international style.
British English (Day-Month-Year)
In the UK, Ireland, Australia, and many other English-speaking countries, the day precedes the month.
- Written: 4 July 2024 or 4th July 2024
- Spoken: “The fourth of July, twenty twenty-four”
- Numerical: 04/07/2024
Key takeaway for business: If you’re emailing someone in a different country, always write out the month. Use “10 October 2025” instead of “10/10/25.” It’s the only way to be 100% sure your reader understands.
How to say the year in English
How you say the year usually depends on the era:
- Years before 2000: Split the year into two parts.
- 1999 is spoken as “nineteen ninety-nine.”
- Years from 2000–2009: Usually spoken as “two thousand” followed by the number.
- 2005 is “two thousand five.”
- Years from 2010–Present: You can use two methods.
- 2026 can be “twenty twenty-six” (most common) or “two thousand twenty-six.”

Pronouncing dates: A comparison table
The following table demonstrates how to speak the date in both American and British dialects. Note the use of “the” and “of” in the British style, which is often omitted in American speech.
| Date | American English (spoken) | British English (spoken) |
| January 1st | January first | The first of January |
| February 14th | February fourteenth | The fourteenth of February |
| May 5th | May fifth | The fifth of May |
| October 31st | October thirty-first | The thirty-first of October |
| December 25th | December twenty-fifth | The twenty-fifth of December |
Essential grammar rules for dates
Using ordinal numbers
When writing, you can use cardinal numbers (1, 2, 3) or ordinal numbers (1st, 2nd, 3rd). While modern style guides increasingly suggest using cardinal numbers for simplicity, you should almost always use the ordinal sound form when speaking.
- Write: July 4
- Say: July fourth
Prepositions: “In” vs. “On”
Choosing the right preposition depends on how specific you are trying to be:
- Use “On” for specific days: “The party is on October 31st.”
- Use “In” for months or years: “My birthday is in October” or “I graduated in 2020.”

Which format should you choose?
Choosing between American and British styles usually comes down to your audience. While regional rules provide a framework, global English is increasingly flexible. When writing for an international audience, spelling out the month (e.g., 12 May 2026) is the most effective way to ensure your message is understood without confusion.
By mastering these small linguistic shifts, you can navigate professional and social settings with confidence, ensuring you never miss a deadline or an invitation.
