Use "circa" at the end of a sentence

Can I write "I will be able to finish my work by the beginning of August circa."?

I know that I could write "I will be able to finish my work circa by the beginning of August.", I just prefer the first option and I just wanted to ask if it is permitted to write it that way.


The word circa is not typically used in that context. The Oxford Dictionary says

circa

PREPOSITION

(often preceding a date) approximately.

‘the church was built circa 1860’

The sentence is clumsy in both versions and the use of circa seems pretentious. I suggest rewriting the sentence in one of these ways:

I will be able to finish my work by the beginning of August.

I will be able to finish my work some time around the beginning of August.

I will be able to finish my work in the first week of August.
