Date Calculator
About Date Calculator
Work with dates accurately in one place. Pick a mode—Days Between Dates, Add Days to a Date, or Subtract Days—and provide a start date plus either an end date or an exact day count. The calculator returns the precise result, respecting calendar boundaries and leap years so you never miscount. It’s excellent for project planning, deadlines, travel itineraries, and compliance reporting. The simple interface prevents format errors and shows outcomes in clear, readable text suitable for copy‑paste into documents or emails.
