* "July" is a noun, not a verb. You can't use "start" as a verb with July directly.
* "Started" is the past participle. It should be used with a helping verb (like "has" or "was") to form a passive voice.
Here are some correct ways to express the same idea:
* "July has just begun." This uses the correct verb "begin" and expresses the start of the month.
* "It's the beginning of July." This focuses on the time period.
* "July has just started." This is a more informal way of saying it.
Remember, when using "start" in the passive voice, you need a subject to be acted upon. For example, "The month of July has just been started."
