I was going for the idea that a time can also be a location. You can revisit a time of year, in the same way you can go back to a house that you used to live in.
While writing, you are more interested in seeing what happens with you in the process, because all that writing is just you sorting through and exploring and wondering and figuring out your thoughts.
A certain month or a certain season can elicit a certain emotional response. That is certainly true for anyone who has a negative anniversary on their calendar, the approach of that month brings the feeling of being very much back in another room. It is a time that stands outside the rest of the year.
