Best practice
When using "have elapsed since", ensure the verb tense in the subsequent clause aligns logically with the timeframe. For instance, use the past perfect tense to describe an action completed before the elapsed time.
Common error
Avoid using the simple past tense in the clause following "have elapsed since" when referring to an action that occurred before the elapsed period. Using past perfect ensures clarity. For example, "Five years have elapsed since I had graduated" is better than "Five years have elapsed since I graduated."
