Frequently Asked Questions
What does inclusive counting mean?+
Inclusive mode counts both the start date and the end date, adding one day to the elapsed difference.
Can the start date be after the end date?+
Yes. The calculator reports the absolute elapsed difference regardless of which date is entered first.
Does daylight saving time affect the result?+
No. The tool compares calendar dates, so clock changes and time zones do not add or remove a day.
