✅ 23th or 23rd – Quick Answer

The correct form is 23rd ✅
23th is incorrect ❌

✔️ Examples:

My exam is on the 23rd.
The meeting is set for July 23rd.
She was born on the 23rd of May.

👉 Simple rule:
If a number ends in 3, use “rd” (except 13).

📖 The Origin of 23th or 23rd

To understand 23th or 23rd, we need to look at ordinal numbers. These are numbers that show position, like first, second, and third.

In old English:

1 → first (1st)
2 → second (2nd)
3 → third (3rd)

Over time, these words became short forms:

st, nd, rd, th

So when we say 23, we look at the last digit:

23 ends in 3
So it follows the rule → 23rd

👉 Why do people write “23th”?
Because most numbers use “th” (like 4th, 5th, 6th). People think the same rule works for all numbers but it doesn’t.

👉 Important exception:

11, 12, 13 → always use th
So: 13th (not 13rd)

Just remember one simple rule:
If the number ends in 3, use rd except for 13.
