a formal way to say "around"

[herbivorie]

Can I use "around" to mean approximate time in a formal document? For example,

The company will start the ad campaign around July to Semtemper this year.

(By this "around", I want to say that the exact timing is unknown. It could be late June or early October.)

If it can't be used in a formal document like this, please tell me a better way to say it.

As the exact date is unknown, why not say 'sometime between June and October'?

Not a teacher.

No, it doesn't work in this context. As I wrote in my post, it could be late June or early October. It's not "sometime BETWEEN June and October".

I'll wait for a reply from a native speaker.

I meant, "it could also be late June or early October.

I am not clear. Will it start in late June or in early October and at no time in between? That does not fit with the original phrasing "around July to September this year".

 

[Matthew Wai]

If 'at no time in between', should it be 'around July or September this year'?

I would use either in late June or in early October.

By "around July to September", I meant that the approximate time is "July to Semtember".
So, it could be late June, July, August, September, or early October.

I corrected post#3.

If the possible date may vary so widely, why not say 'later this year'?

But in post #3, you still say "It's not "sometime BETWEEN June and October" but in post #7, you said "it could be late June, July, August, September, or early October." July, August and September are all between June and October.

The only way to say it is "The company will start the ad campaign sometime between late June and early October". That only refers to the start date, though.

By that, I meant "It's not only sometime between June and October".

What I'm looking for is just a formal version of "around" (if any), like "approximately" is a formal version of "about".

In some contexts "approximately" would be a perfectly good synonym for "around". However, the problem you have here is that regardless of which one of those two words you use, it doesn't make sense to follow them with the words "July to September" or "late June to early October" or anything similar. It's the use of the word "to" between the months that is causing the issue. If you're going to give a time period or a range of months, you can't begin the sentence with "It will start around ...". It can't possibly start from July to September, or start around July to September or from any month to any other month. The ad can start on a specific date or ​start around a specific date.
