Use the Convert Units mode to enter time in any combination of days, hours, minutes, and seconds. The tool will instantly show the equivalent in all other units. For example, entering 2 days and 12 hours will show the total as 60 hours, 3600 minutes, or 216000 seconds.

Yes, each calculation result includes a copy button that copies the formatted duration or date to your clipboard. This makes it easy to paste results into documents, emails, or other applications without having to manually type the values.
