When it is useful
Useful for durations, project estimates, media lengths, experiments and logs. For employment calculations, use the work-hours or annual-leave tools because a working day is not always eight hours.
Accuracy and unit standards
Calendar days here always mean 24 hours. Months and years are deliberately excluded because their lengths vary; treating every month as 30 days would give misleading results.
