totalday

Totalday is a term used in timekeeping and data analytics to refer to the complete set of hours within a single calendar day as observed in a specific time zone. In practice, it often means the sum of all time intervals that fall on a particular date in a dataset, such as work hours recorded for employees or usage minutes for a service. The concept is distinct from the calendar day itself and the business day; totalday focuses on the actual time accumulated within that date, which may be affected by issues such as partial days, overnight shifts, or missing data.

In computing contexts, totalday can be calculated by grouping time entries by date and summing their durations. This helps generate daily totals for reporting, invoicing, or performance dashboards. The definition of totalday can vary by organization: some define it as midnight-to-midnight in local time, others use standardized time frames or include daylight saving changes.

When using the term, it is important to document the exact borders used (time zone, DST handling) and whether the totalday is inclusive of partial days or requires full-day coverage. Potential ambiguities arise when data cross midnight or when time data are recorded in multiple time zones.
