Best practice
For clarity, specify the unit of time (days) immediately after the numerical value. This prevents misinterpretation, especially when dealing with different units of measurement.
Common error
Avoid writing "minimum of five days before" instead of "a minimum of five days before". The article 'a' is important because it correctly expresses that five days is the lowest acceptable limit.
