Suppose there is a certain condition with the time interval, only during which it holds. For example,
Condition: High humidity / Interval: June to September
What I want now is describing that 'there are some texts like above', but I prefer it as concise as possible as in the business context. I guess it is grammatically safe to write as below,
A condition with the interval during which it holds.
but can I shrink it down further by using 'for' instead of 'during'?
A condition with the interval that it holds for.
