Does this account for leap years?
The calculation accounts for leap years when computing years and days, so February 29 is handled correctly.
How are business days calculated?
Business days exclude Saturdays and Sundays. Public holidays are not subtracted since they vary by country and region.
Is my data sent to a server?
All date calculations run locally in your browser using JavaScript's Date API. No data is transmitted anywhere.
Can I calculate past dates?
You can enter any start and end date, including dates in the past. The result shows the absolute difference regardless of order.
Why does the month count sometimes differ from what I expect?
Months vary in length, so the month count is calculated by stepping through calendar months rather than dividing days by 30, giving an accurate calendar-based result.
