30th or 30st – Which is Correct?

When it comes to writing dates, one common source of confusion is whether to use “30th” or “30st” for the 30th day of a month. While it may seem like a trivial matter, getting it wrong can make your writing appear careless and can even lead to misunderstandings. So, let’s clear things up and find out which is the correct option.

The correct form to use is “30th.” This is because “th” is the appropriate suffix to use when referring to the ordinal number 30th. “St,” on the other hand, is used for the ordinal number 1st, which is unique among all the numbers.

To understand this better, let’s take a look at some examples:

1. On the 1st day of the month, we have a staff meeting.
2. We are going on a vacation from the 15th to the 20th of July.
3. The project is due on the 30th of this month.

In each of these examples, you can see that “st” is used for the first day, while “th” is used for all the other ordinal numbers, including the 30th.

Using the correct form shows that you not only understand the rules of grammar but also pay attention to detail. It demonstrates your commitment to clear communication and helps avoid any confusion that might arise.

Imagine if you wrote “30st” instead of “30th” on an important document. It would certainly raise eyebrows and possibly lead to questions about your attention to detail. On the other hand, using the correct form, “30th,” would assure the reader that you are knowledgeable and professional.

In the IELTS exam, attention to detail is crucial. The test assesses your ability to use the English language accurately, and using the correct form in writing dates is one way to showcase that ability. Examiners are looking for candidates who can demonstrate a good command of English grammar and vocabulary, which includes using the appropriate ordinal suffixes.

To summarize, “30th” is the correct form to use when writing the 30th day of a month. It is important to pay attention to these details to convey professionalism, clarity, and accuracy in your writing. So, the next time you need to write a date, remember to use “30th” – you’ll be one step closer to achieving your desired IELTS score and impressing anyone who reads your work.
