Final Answer:
The given statment the calendar day of return, regardless of hour is counted as a day of duty is true (option A).
Step-by-step explanation:
The statement "The calendar day of return, regardless of the hour, is counted as a day of duty" is true (option A). This means that even if a person returns from duty partway through a day, the entire calendar day is considered a day of duty. This practice is often employed in various professions, such as military service or certain job contracts, where the full day is accounted for regardless of the specific hours worked.
The rationale behind this approach is to simplify the tracking and calculation of duty days. It ensures a straightforward method of accounting, eliminating the need for detailed hour-by-hour calculations.
This method is particularly relevant in scenarios where individuals may return from duty at different times during the day, making it logistically challenging to precisely determine hours worked on the day of return.
