Frequently asked questions
How is this different from the Date Calculator's difference mode?
The Date Calculator only compares calendar dates (ignoring time of day). This tool factors in the specific time on both ends, giving a precise duration down to the second — useful for events, project timelines, or anything where the exact start and end moments matter.
What if the end point is before the start point?
The duration is shown as zero rather than a negative value — swap the two inputs if you intended the gap measured in the other direction.
