Work out contract expiry date instantly with clear inputs, formula shown and shareable results.
A 24 month contract from 15 January 2026 expires on 15 January 2028, a term of 730 days. With 90 days notice required, the decision deadline is 17 October 2027 - and missing it usually triggers automatic renewal, which is the trap in evergreen contracts.
Expiry date
expiry = start date with the month advanced by the term
Notice deadline
deadline = expiry - notice days
Most contracts with an evergreen clause renew automatically for a further term. Diarising the deadline rather than the expiry is essential.
A 31 January start on a one month term is conventionally 28 or 29 February. Contracts should state the convention explicitly.
