If you have ever paused mid-sentence wondering whether to write 22th or 22nd, you are not alone. This is one of the most common ordinal number mistakes in English, especially when writing dates, birthdays, and invitations. The confusion usually happens because English ordinal suffixes do not follow one single pattern for every number.
In this guide, you will get a clear, simple answer to the 22th or 22nd question, learn the grammar rule behind it, see real examples for every month, and avoid the mistakes that even native speakers make.
22th or 22nd – Quick Answer
The correct spelling is 22nd, not 22th. Whenever you compare 22th or 22nd in a sentence, 22nd is always the grammatically correct choice in standard English.
Simple Rule
Ordinal numbers ending in 2 (except 12) take the suffix -nd. That is why 2nd, 22nd, 32nd, and 42nd all end in -nd, while 22th does not exist in correct English.
Is 22nd or 22th Correct?
22nd is correct. English ordinal numbers are built from cardinal numbers plus a suffix, and the suffix depends on the final digit of the number. Since 22 ends in 2, the correct ordinal form is 22nd, following the same pattern as 2nd.
According to Merriam-Webster, ordinal numbers describe position in a sequence, and 22nd is the standard recognized form for the number 22.
Which is Correct: 22th or 22nd?
When people search for 22th or 22nd, they are usually double-checking a date, an age, or an anniversary before publishing or sending it. The safe rule to remember: 22th is never correct in any context, formal or informal. Only 22nd is accepted in dictionaries, style guides, and everyday writing.
The Origin of 22th or 22nd
The confusion between 22th or 22nd goes back to how English ordinal suffixes developed from Old English number forms. Most ordinals simply add -th (four becomes fourth, six becomes sixth), which is why some writers assume every number follows the same pattern, including 22.
However, the numbers 1, 2, and 3 kept irregular endings (first, second, third) rather than adopting -th, and this irregularity carries over into every number that ends in 1, 2, or 3, including 21st, 22nd, and 23rd.
British English vs American English Spelling
Good news: there is no British vs American spelling difference for 22th or 22nd. Both dialects use 22nd. The only real difference is date order, similar to other formatting quirks covered in our guide on due to or do to, where meaning rather than spelling causes the mix-up.

| Region | Date Format | Example |
| American English | Month Day, Year | June 22nd, 2026 |
| British English | Day Month Year | 22nd June 2026 |
Which Spelling Should You Use?
Always use 22nd. Whether you are writing an email, a school assignment, a birthday card, or a news article, 22nd is the only correct spelling across both British and American English.
Audience-Based Usage
● Academic writing: use 22nd, never abbreviate further.
● Business emails: 22nd reads as professional and error-free.
● Social media captions: 22nd still looks correct and polished.
● Formal invitations: 22nd is the only accepted form.
22th Birthday or 22nd Birthday: Which is Correct?
It is always 22nd Birthday, not 22th Birthday. This is one of the most searched versions of the 22th or 22nd question because birthday wishes are shared so often on cards, cakes, and social posts.
Just like people mix up taken vs taking in everyday sentences, the 22th or 22nd mistake happens because the writer is thinking of the number 22 without pausing to apply the correct ordinal suffix.
Is It Happy 22th or 22nd Birthday?
The correct greeting is Happy 22nd Birthday. Writing Happy 22th Birthday is a common but noticeable error that can make invitations, cards, or captions look unpolished.
February 22nd or 22th: Which Is Correct?
February 22nd is correct. Whether you are labeling a calendar event or writing a formal letter, the date should always read February 22nd, never February 22th.
22th or 22nd September
The correct form is 22nd September (British order) or September 22nd (American order). Either way, the number itself is always written as 22nd.
22th or 22nd April
Write April 22nd or 22nd April, depending on your regional style. Never write April 22th, since 22th is not a recognized ordinal number in English.
22th or 22nd June
June 22nd is the correct format for this popular summer date, often used for graduations, weddings, and birthdays. 22th June is incorrect in every style guide.
22th or 22nd October
October 22nd follows the same rule as every other month. The number 22 always takes the -nd suffix, regardless of which month it appears next to.
22th or 22nd December
December 22nd is correct, especially common in holiday cards and year-end schedules. Avoid writing December 22th in any greeting or official document.
Is It 22th or 23rd?
This compares two different numbers, not two spellings of the same number. 22 is written as 22nd, while 23 is written as 23rd. Neither number ever takes the -th suffix, since both end in 2 and 3 respectively.
12th or 12nd: Which Is Correct?
12th is correct, not 12nd. Numbers ending in 11, 12, and 13 are exceptions to the usual pattern and always take -th, which is why 12th, 11th, and 13th look different from 21st, 22nd, and 23rd.
Common Mistakes with 22th or 22nd
Even confident writers occasionally slip when typing quickly, especially in messages, invitations, and social captions.
Common Errors and Fixes
Incorrect Example
“See you on the 22th of July.”
Correct Example
“See you on the 22nd of July.”
Why the Mistake Happens
Writers often default to -th because it is the most common ordinal suffix in English, forgetting that numbers ending in 1, 2, or 3 follow their own pattern.
