If you are going to pitch a story you may want to consider they day you pitch it on. The day you choose could mean a lot for whether or not your story gets published.

The best time in terms of burying the story is also the best time to irritate the media and perhaps provoke their greater interest, which would be after their deadline on a Friday afternoon, because they're always suspicious of bad news release that late. At the same time, the best news days categorically tend to be, for routine news, Tuesday through Thursday. So with all that said, I would identify Monday as the day that tends to be very busy, and therefore maybe your story gets lost in the shuffle, or buried in the shuffle, versus a day that would either provoke suspicion or be more wide open for news coverage.
