Our study is the first to our knowledge to use U.S. time diary data to closely examine the association between parents’ work arrangements and time use in the pandemic. We estimate time use prior to the pandemic and differences in time use between 2017–2018 and 2020. Our main analyses use matching to assess differences in: (1) broad categories of time use, including paid work, childcare, parent–child copresence, supervisory parenting, and housework; (2) detailed parenting activities, including routine, play, teaching, and management; and (3) paid work environments, including time when children are present, supervisory parenting while working, work spells, and work outside of 9:00 a.m.–17:00 p.m. weekday hours.
