Expert writing Tips

Best practice

When writing about durations, use "three years" for general contexts. For added precision, especially in technical or formal writing, specify as "36 months" or "a three-year period".

Common error

Avoid writing "three year's" when referring to a duration. The correct form, without the possessive apostrophe, is "three years". The possessive form "three year's work" is correct, if you are trying to indicate that a work possesses that duration.
