Frequently asked questions
Does this count calendar days or business days?
The headline answer uses the calendar, weekends included. The stat strip also shows how many weekdays (Monday to Friday) fall inside the span, which is the business-day count without holidays.
How are month-end dates handled?
Months are added by calendar month with day-of-month clamping: one month after January 31 is the last day of February, not March 3. This matches how billing cycles and legal deadlines usually work.
How do I count days between two specific dates instead?
Use the date difference calculator on this site: pick both dates and it returns the gap in days, weeks, months, and years.
