Frequently asked questions
Are weekends and holidays excluded from business days?
Weekends are excluded automatically (Saturday and Sunday). Public holidays vary by country and are not subtracted.
Why are months and years not always exact?
Months have 28–31 days. We compute calendar months by aligning the day-of-month, so going Jan 31 → Mar 1 is 1 month and 1 day, not '31 days = 1 month'.
Does the order of dates matter?
No. We always compute |To − From|, so swapping the two dates gives the same result.
