How Does the Duration Calculator Work? (Formula & Step-by-Step)

Calculate the exact time difference (duration) between two specific dates and times.

Duration = |Date2 − Date1|

Variable	Description & Context	Measurement Unit	Sample Input
`Start Date & Time`	Start Date & Time	Standard	`e.g. 100`
`End Date & Time`	End Date & Time	Standard	`e.g. 100`

Key Terminology & Definitions (Duration Calculator)

Understanding these foundational concepts ensures you interpret your results with precision:

Start Date & Time: The quantitative parameter for start date & time used by the Duration Calculator calculation algorithm.
End Date & Time: The quantitative parameter for end date & time used by the Duration Calculator calculation algorithm.

Frequently Asked Questions

Convert both start and end times to total elapsed seconds from midnight. If the end time is on the next day, add 24 hours (86,400 seconds). The difference is converted into hours, minutes, and seconds.

You can subtract designated break minutes from the total duration to determine net productive work hours for payroll or timesheets.

Divide the minute count by 60 and add to the whole hours: Decimal Hours = Hours + (Minutes / 60). For example, 7 hours and 45 minutes equals 7 + (45/60) = 7.75 decimal hours.
