I have not submitted work to an agency in a few years, but I will be within the next six months. I know from my past experience that certain agents were closed to submissions during various months. For instance, I remember the holiday season most agencies were closed, and it seemed like the majority were also closed for a time in summer months. I had an agent request a full ms in November, and they ended up having to put it aside due to bad timing. If you finish a ms during a certain time of the year, is it wise to pick the correct month to submit? If so, what is the best time for submission in general??
