Maturity
A bond’s maturity date is part of its contract. It tells you when the instrument is scheduled to repay principal, assuming the issuer meets its obligations.
Maturity alone does not capture every price risk.
Duration
Duration incorporates the timing of cash flows and is commonly used as an approximation of interest-rate sensitivity.
Higher duration generally means a larger price response to a given change in yields, all else equal.
Why both matter
Two bonds with similar maturities can have different coupons and therefore different durations.
Looking at both gives a better picture than using maturity alone.
