The Journal of Circadian Rhythms is an open access, peer-reviewed online journal that publishes research articles dealing with circadian and nycthemeral (daily) rhythms in living organisms, including processes associated with photoperiodism and daily torpor, whether metabolic or behavioral. The Journal of Circadian Rhythms aims to include both basic and applied research at any level of biological organization (molecular, cellular, organic, organismal, and populational). Studies of daily rhythms in environmental factors that directly affect circadian rhythms are also pertinent to the journal's mission. The study of circadian rhythms has experienced enormous growth in the recent past. From fungi and plants to birds and mammals, and from molecules and cells to organisms and populations, research on circadian rhythms has advanced at full speed into the 21st century. The Journal of Circadian Rhythms provides the first open access journal dedicated to this expanding field.

Review & acceptance
Review time and acceptance
Review time from article dates manuscript dates registered with PubMed · to
Too few articlesOnly 8 articles from the last 24 months carry both submission and acceptance dates, too few for a median
Only articles that were accepted and published are counted, not the time spent on rejected manuscripts, so this usually runs longer than a publisher's "time to first decision".
