Expert writing Tips
Best practice
Use the simple past tense ("started") when referring to a specific time in the past. For example, say "The meeting started yesterday" instead of "has started yesterday".
Common error
Avoid combining the present perfect tense (which indicates an action completed at an unspecified time in the past) with specific past time adverbs (like "yesterday"). This creates a grammatically incorrect sentence.

Ludwig's WRAP-UP
The phrase "has started yesterday" is grammatically incorrect due to the misuse of the present perfect tense with a specific past time adverb. As Ludwig AI confirms, this combination is not standard English. Instead, the simple past tense should be used (e.g., "started yesterday"). The goal is to convey an action that began on the previous day, but incorrect grammar hinders effective communication. To ensure clarity and correctness, it's best to avoid combining the present perfect with adverbs like "yesterday" and instead use the simple past. Correct alternatives include phrases such as "started yesterday" or "began yesterday".

FAQs
Why is "has started yesterday" grammatically incorrect?
The present perfect tense ("has started") is used for actions that happened at an unspecified time in the past or have relevance to the present. "Yesterday" specifies a definite time in the past, so the simple past tense (e.g., "started yesterday") is required.
What's the correct tense to use when describing something that began on a specific date in the past?
Use the simple past tense. For example, instead of "The project has started on Monday", say "The project "started on Monday"".
What are some alternative ways to say something "has started"?
Depending on the context, you could use phrases like "began", "commenced", or "was initiated". If you want to show a connection to the present, you can use the present perfect with different wording, such as "the process has begun".
Can I use the present perfect tense with adverbs of time?
You can use the present perfect with adverbs like "already", "yet", "ever", and "never", which don't specify a definite time. However, avoid using it with adverbs that indicate a specific time in the past, like "yesterday", "last week", or "in 2020".
