9 AM or 9AM – Which is Correct?

When it comes to writing the time, there is often confusion regarding whether to use a space between the numeral and the abbreviation “AM.” Some people write it as “9 AM” while others opt for “9AM.” So which one is correct? Let’s delve deeper into this matter and find out.

To start with, it is important to acknowledge that both “9 AM” and “9AM” are widely used, and there isn’t necessarily a right or wrong answer. The choice between one format or the other often boils down to personal preference or the specific style guide one is following.

That being said, there is a widely accepted convention when it comes to writing time and the use of a space between the numeral and the abbreviation “AM.” According to most style guides and grammatical conventions, it is generally recommended to employ a space, making “9 AM” the more preferable format.

Using a space between the numeral and the abbreviation helps to enhance the clarity and readability of the written time. By creating a visual separation between the numeral and its modifier, it becomes easier for the reader to quickly understand the time indicated. It also provides a clear distinction between the numeral and other elements within the sentence.

Consider the following sentence: “I have a meeting at 9AM.” Without a space, the sentence might appear cluttered and could potentially be misread as “9AM” being a single word instead of a time indication. On the other hand, by writing it as “9 AM,” the reader may better comprehend the sentence as “nine in the morning.”

Furthermore, using a space helps to maintain consistency within a piece of writing. When adhering to the convention of including a space between the numeral and “AM,” it is easier to apply this consistency throughout the entire document. This consistency adds to the overall professionalism and coherence of the writing.

Let’s consider some more examples to illustrate the clarity gained by using the format “9 AM”:

1. The event starts promptly at 10AM. (Without space)
2. The event starts promptly at 10 AM. (With space)

In the first example, the lack of a space could potentially cause confusion, whereas in the second example, the presence of a space allows for a smoother and clearer reading of the time.

While the inclusion of a space is the more generally accepted form, it is worth mentioning that certain style guides or publications may have their own rules or preferences. In some cases, you may encounter instances where the space is omitted. It is always advisable to consult relevant style guides or manuals, especially in academic or professional writing, to ensure adherence to specific conventions.

In conclusion, the choice between “9 AM” and “9AM” ultimately depends on personal preference and the style guide being followed. However, to uphold clarity, consistency, and readability, incorporating a space between the numeral and the abbreviation “AM” is generally recommended. Keep in mind that specific style guides or publications may dictate their own rules, so it is wise to refer to those guidelines when necessary.
