Many of those in the (seemingly) cyclical throes of law review article submission process (particularly folks on the tenure track) eventually wonder about, among other issues, submission timing. Not quite content to rely on mere anecdote (or "urban legend" passed down from more seasoned colleagues), Shima Baradaran (BYU) is in the early stages of a project that seeks, in part, to hold commonly-held perceptions up to data (albeit limited data involving a single law review--BYU L Rev). Shima's efforts (at this point, essentially an early-stage case study) have already generated multiple blog posts on PrawfsBlawg.
Shima's first post on timing includes the following take-away: "many law reviews give offers out in waves and submitting your article in the first wave or second wave may be advantageous." A second, follow-up post on timing implies that folks seeking to maximize possible attention to their submissions should: avoid submitting on March 1, and, more generally, on Thursdays. While I'm not at all sure what the results might mean in a larger sense, more data involving more law reviews will assist.
