Count days like a calendar pro
The difference counts full days from the start date to the end date — Friday to Monday is 3 days; add 1 if you want the end day included. The weekday count tallies only Monday through Friday in the same range, handy for rough project or delivery estimates (public holidays are not subtracted).
Adding or subtracting days answers questions like “what date is 90 days from today?” — deadlines, return windows, notice periods. Everything runs in your browser; nothing is sent anywhere.
