Frequently Asked Questions
Quick answers to common questions about the Date Difference calculator.
Does the elapsed-day total include the end date?
No. It uses end date minus start date. An explicitly inclusive calendar-date count would add one.
How are business days counted?
Monday through Friday are counted inclusively at both ends. Holidays are not removed.
Can I count days until an event?
Yes. Select Days until a date and choose the target.
What happens if the second date is earlier?
The magnitude is calculated and the direction indicates that the second date is earlier.
Can I see the difference as years, months, and days?
Yes. The result shows the calendar breakdown alongside the elapsed-day total, so a long span stays readable.
