weekdayonly

Weekdayonly is a term used to describe schedules, processes, or data constraints that apply only on weekdays, typically Monday through Friday, and exclude weekends. In many contexts, the term implies that Saturday and Sunday are not counted for timing, availability, or counting purposes.

Applications include business calendars, employee scheduling, and project timelines where work ordinarily occurs on weekdays. Weekday-only policies may also exclude public holidays, or they may treat holidays as non-working days depending on organizational rules. In public-facing services, weekday-only modes can limit access or activation to business days.

In software, weekday-only logic appears in date and time utilities, where a function or option restricts operations to weekdays. For example, a calendar app might offer a weekday-only reminder, a job scheduler might trigger tasks only on business days, and data processing pipelines can aggregate metrics by weekday to align with business activity. Some analytics and reporting workflows use weekday-only windows to reflect typical user engagement patterns or operational capacity.

Considerations include locale (some cultures consider weeks differently), time zones, and holiday observance. The definition of a weekday may hinge on local business practices and legal requirements, and systems may need to accommodate exceptions for holidays or special circumstances.
