Expert writing Tips

Best practice

When describing events that occurred over a limited timeframe, consider using "span of days" to emphasize the period in question. For example, "The project's success hinged on the critical span of days leading up to the deadline."

Common error

Avoid using "span of days" when the timeframe is already clear. Redundant phrasing, such as "during the span of five days", can be streamlined to "during five days" for better clarity.
