Frequently Asked Questions

How do I write "18 August" in American English?
The correct American English format for "18 August" is "August 18th, 2026". This follows the American pattern of Month + Day + Year, with ordinal numbers for the day (18th) and a comma before the year.
Why do I need a comma in "August 18th, 2026"?
In American English, the comma is required between the day and year to separate the date elements clearly. This is a standard punctuation rule that distinguishes American format from British format, which doesn't use a comma.
Can I write "Aug" instead of "August"?

What's wrong with writing "18th August 2026"?
"18th August 2026" is the British English format, which puts the day first. For American English and TOEFL, you should use "August 18th, 2026" with the month first. The British format also doesn't use a comma, which is required in American format.
