Expert writing Tips

Best practice

When specifying a timeframe, ensure clarity by using "period through" to indicate the inclusive endpoint of the duration. For example, "The data collection period through December 31st includes all data received on that day."

Common error

Avoid using "period to" when you mean to include the final date or event. "Period through" clearly indicates that the specified end point is part of the timeframe.

Ludwig's WRAP-UP

The phrase "period through" is a common and acceptable prepositional phrase used to specify an inclusive timeframe. As shown by Ludwig, its primary function is to define the duration of an event, activity, or condition up to and including a particular endpoint. While grammatically correct, its absence in formal grammar guides makes understanding context crucial. It is most frequently found in news and media, science and encyclopedic contexts, with a neutral to professional register. To prevent errors, remember to use "period through" when you want to include the final date or event in your timeframe. Consider alternatives like "period until" or "time frame ending" when a different emphasis is desired.
