daypatterns

Daypatterns refer to the regular and repeating arrangements of activities and behaviors that occur within a 24-hour day or across days. These patterns can be observed at multiple levels, including individuals, households, organizations, and larger systems such as cities or economies. Daypatterns capture when people or processes tend to act, and how those tendencies change by day of the week, season, or context.

Data and methods used to study daypatterns come from time-use surveys, sensor networks, smart meters, call and location records, and transportation data. Analysts apply time-series analysis, frequency analysis, clustering, and sequence mining to identify common templates, their timing, and how often they occur. Visualization of daily or weekly activity profiles is a common product of such analyses.

Applications of understanding daypatterns include energy demand forecasting, urban and transportation planning, workforce scheduling, and service design. For example, residential electricity usage often shows morning and evening peaks, while weekday commuting exhibits regular rush hours. Daypatterns also inform epidemiological contact modeling and marketing strategies by revealing when people are most accessible or active.

Limitations and considerations include privacy concerns, sampling bias, and the variability of patterns across individuals and groups. Daypatterns can shift due to cultural differences, policy changes, technological adoption, or external shocks such as pandemics or economic events. Recognition of daypatterns supports more efficient resource use, better service provision, and a clearer understanding of everyday human activity.
