How this count works
Seconds through weeks use fixed conversion factors. The month and year rows use the average length of the Gregorian calendar, so they are approximations for a real date span.
A duration day here is a fixed block of hours. A local calendar day around a daylight-saving change can be shorter or longer. Months and years need actual dates for a calendar answer.
A worked example
72 hours equals 3 days. The average-month result is 0.098565, which does not name a calendar date.
