02 / HOW TO CHOOSE

Start with
the right question.

Date calculations can skip weekends but do not automatically account for public holidays. Age uses completed calendar years, months and days. Time duration compares clock times and does not adjust for daylight saving transitions.

WORKED EXAMPLE

From 9:00 a.m. to 5:30 p.m. is 8 hours and 30 minutes. A date interval and a business-day count can differ substantially when weekends are involved.
