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.
What time zone is 'today'?
Dates are computed in UTC, so near midnight your local 'today' may differ by one day from the server's. The math itself is the same either way.
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.
