You’re typing a date, a birthday card, or a quick text. Then you freeze. Is it 22th or 22nd? That tiny ending can shake your confidence. The good news? The answer is simple, and it never changes.
This guide clears up the mix-up in plain English. You’ll get the rule, real examples, and a handy memory trick. We’ll also cover dates, birthdays, and monthsaries. You’ll even see how British and American writers format the same day.
22th or 22nd – Quick Answer
The correct form is 22nd. The form 22th is always wrong.
Here’s why. The number 22 ends in 2. Its spoken form is twenty-second. The word “second” ends in “nd.” So you write 22nd. The 22th or 22nd debate ends right there.
Simple Rule
The last digit decides the ending. Check it, then pick your suffix.
- Ends in 1: use st (21st, 31st)
- Ends in 2: use nd (22nd, 32nd)
- Ends in 3: use rd (23rd, 33rd)
- Ends in 0 or 4 to 9: use th (24th, 30th)
- Exception: 11, 12, and 13 use th
22th or 22nd Monthsary
Write 22nd monthsary. Never write 22th monthsary.
A monthsary is a monthly anniversary. Couples use it to celebrate each month together. The word is popular in the Philippines. It’s informal, so major print dictionaries reportedly don’t list it. The ordinal rule still applies, though.
Been together 22 months? Then you’re celebrating your 22nd monthsary. For example: “Happy 22nd monthsary, my love!” The same goes if your monthly date falls on the 22nd.
The Origin of 22th or 22nd
The ending comes straight from the spoken word. English borrows each ordinal ending from its full word. Fourth gives us 4th. Third gives us 3rd. Second gives us 2nd, so twenty-second becomes 22nd.
“Second” traces back to the Latin word secundus, meaning “following.” It reached English through French. Long ago, writers also used short forms like 22d. You can still spot them in old letters.
So why do people write 22th? Habit, mostly. Most ordinals end in th, so the 22th or 22nd mix-up feels natural. Your brain simply goes on autopilot. Spoken English helps here. Say the number aloud and you hear “second,” not “twenty-two-th.” That sound clue points straight to nd.
British English vs American English Spelling
The suffix is spelled the same in both: 22nd.
Only the date order and punctuation change. So this isn’t a true spelling fight. It’s a formatting choice.
Comparison Table
| Feature | British English | American English |
| Suffix | 22nd | 22nd |
| Written date | 22nd September 2026 | September 22nd, 2026 |
| Spoken date | the 22nd of September | September twenty-second |
| Short date | 22/09/2026 | 09/22/2026 |
| Suffix optional? | Often dropped: 22 September | Often dropped: September 22 |
Notice the pattern? Every row keeps the same suffix. Only the order of day and month moves around. If your readers span both regions, the no-suffix style keeps things safe.
Which Spelling Should You Use?
Use 22nd every time, because 22th isn’t a real form.
Your only real choice is date style. Weighing 22th or 22nd? Pick 22nd, then stay consistent across your whole page.
Audience-Based Usage
- US readers: September 22nd or September 22
- UK and Commonwealth readers: 22nd September or 22 September
- Formal reports: drop the suffix, as in 22 September 2026
- Casual chats and captions: 22nd works perfectly
Common Mistakes with 22th or 22nd
The biggest mistake is writing 22th.
Other slips include 22st, 22rd, and 22sd. Each one guesses the ending wrong. Let’s fix them.
Common Errors and Fixes
| Wrong | Right | Reason |
| 22th | 22nd | The number ends in 2 |
| 22st | 22nd | St belongs to 1 |
| 22rd | 22nd | Rd belongs to 3 |
| 22sd | 22nd | Not a standard form |
| 12nd | 12th | 12 is an exception |
Incorrect Example
Her 22th birthday party is on the 22th of May.
Correct Example
Her 22nd birthday party is on the 22nd of May.
Why the Mistake Happens
Habit plays a big part. Most ordinals end in th, so your fingers type it on autopilot. Spelling doubts spread easily too. Plenty of writers also pause over opening or openning, or grately vs greatly. Small endings trip up everyone.
Another slip mixes ordinals with plain numbers. Saying “I’m turning 22nd” is wrong. Use “I’m turning 22” for age. Ordinals show position, so save 22nd for birthdays, dates, and rankings.
Easy Rule for Ordinal Numbers
Look at the last digit, then add st, nd, rd, or th.
This works for any number, however large. So 102 becomes 102nd, and 203 becomes 203rd. Just watch the teens.
You can also write ordinals in words. Then you hyphenate numbers above twenty, as in twenty-second or thirty-second. Formal writing often spells out ordinals below ten, such as first and third. For larger numbers, numerals like 22nd are perfectly fine.
Exceptions
Numbers ending in 11, 12, and 13 always take th.
That means 11th, 12th, and 13th. It also means 111th, 112th, and 113th. Never write 12nd or 112nd. A few words also change spelling, such as fifth, eighth, ninth, and twelfth.
22th or 22nd April
Write it as 22nd April or April 22nd.
Both styles keep the nd ending. British writers prefer 22nd April 2026. American writers prefer April 22nd, 2026. You can skip the suffix too: 22 April or April 22. Many people also know April 22 as Earth Day, so you’ll see this date often.
22th or 22nd in Everyday Examples
Real sentences make the rule stick. Here’s where you’ll use 22nd most often.
Emails
“Please send the report by the 22nd.” Or try: “Our meeting moves to Tuesday, the 22nd.” Clear dates prevent missed deadlines, so double-check every suffix.
News
“Officials confirmed the launch for the 22nd of March.” Newsrooms often skip the suffix, so “March 22” is common too.
Social Media
“Can’t believe it’s my 22nd trip around the sun!” Short posts spread fast, and a wrong suffix spreads with them.
Formal Writing
“Signed this 22nd day of August, 2026.” Legal papers and certificates often use this format.
Invitations
“Join us on the 22nd of July at 6 p.m.” Guests notice small details, so a clean date looks thoughtful.
22th or 22nd August
Write it as 22nd August or August 22nd.
The rule doesn’t change with the month. Use 22nd August 2026 in British style. Use August 22nd, 2026 in American style. Whether it’s a trip, a birthday, or a deadline, the ending stays nd.
