The present research examines whether viewing a calendar depicting the present day as the first day of a new temporal category affects the motivation to pursue ongoing personal goals. Motivation peaked when the calendar's starting day (e.g., Sunday) matched the current day (e.g., Sunday) compared to when the calendar started on a different day (e.g., Monday, Studies 1a, 1b, 2). Viewing a calendar that portrayed the week as starting today (vs. a control calendar) also translated to greater self-reported progress on three personal goals over the next day (Study 2). The calendar format effect was present in both between-subjects designs (Study 1a, 1b, 2) and within-subjects design (Study 3). These studies extend research on the influence of temporal categories on projected goal pursuit to show the impact of calendar formats on motivation in the moment.
