Frequently asked questions
How is this different from the Hours Calculator?
Same underlying calculation — this page leads with the hours+minutes breakdown (e.g. "8 hours 45 minutes"), while the Hours Calculator leads with a single decimal figure (8.75).
Can I see the result in total minutes?
Yes — the "Total minutes" output gives the full duration as a single minute count.
Does this handle durations that cross midnight?
Yes — if the end time is earlier than the start time, it's treated as falling on the following day.
