Expert writing Tips
Best practice
Use "one year earlier" to clearly indicate a specific time period that occurred 365 days (or 366 in a leap year) before a known reference point. Ensure the context makes the reference point clear to avoid ambiguity.
Common error
Avoid using "one year earlier" when "a year ago" is more appropriate. "One year earlier" requires a specific reference point in the past, while "a year ago" refers to the time one year before the present.
