About this tool
This tool calculates the difference between the calendar date and time values you enter. It is suitable for schedules that use the same region and clock basis.
It does not account for time-zone changes or daylight-saving transitions. Use the Time Zone Converter for date and time values in different regions.
Frequently asked questions
Does it account for daylight-saving transitions?
No. It compares the calendar dates and clock values you enter, without adding or removing actual elapsed time for DST or time-zone changes.
What if the end is before the start?
The tool displays an error so a negative duration is not mistaken for a valid result.
Are seconds supported?
The current inputs use minute precision, while the calculation logic can retain seconds.
