When providing an "approximate date for" something, indicate the degree of uncertainty, such as 'early July' or 'late 2024', to manage expectations.
Common error
Avoid using "approximate date" when you have the precise date. Always verify and provide the exact date if it's known, as using an approximation when precision is possible undermines credibility.
