Interactive calculator
This calculator becomes interactive when JavaScript is available. The page still provides its method, limits and related tools without JavaScript.
How it works
Enter the requested values, review the input assumptions, and calculate the result. The result uses deterministic calendar or arithmetic rules on the values you enter. Dates are normalized before calculation, and invalid inputs are rejected.
Result classification
Mathematically exact. The result uses deterministic calendar or arithmetic rules on the values you enter. Dates are normalized before calculation, and invalid inputs are rejected.
Limitations
Exact for the stated rule and valid inputs; it does not decide legal, medical, contractual or policy questions.
