The peer review process represents the driving force of journal development, with reviewers acting as the gatekeepers who ensure that Clocks & Sleep maintains its high-quality standard of published papers. Thanks to the cooperation of our reviewers, in 2020, the median time to the first decision was 21 days and the median time to publication was 44 days.
