Contract Expiry Date Explained

Contract durations are typically measured in calendar months or years. When the calculated expiry date falls on a weekend or federal holiday, the actual effective date depends on what the contract specifies. Many contracts default to the next business day.

This calculator includes US federal holiday data for 2025–2027. For contracts extending beyond that, weekend adjustments are applied but holiday data is not available, so manual verification is recommended.

Common Contract Types and Durations

Residential leases: typically 12 months. Employment agreements: 1–3 years. Service contracts: 6–24 months. Business leases: 1–10 years. Always check the contract language for renewal and termination clauses.

Frequently Asked Questions

When should I send a contract renewal or non-renewal notice?

Most leases require 30–60 days' written notice before expiry. Employment contracts and service agreements vary. Check your specific contract for the required notice period to avoid automatic renewal.

Can I enter the duration in years instead of months?

Enter the duration in months: 1 year = 12, 2 years = 24, 6 months = 6. For partial months, use a decimal (e.g., 1.5 = 1 month 15 days).

Is this calculator accurate for legal purposes?

This tool provides a general estimate for planning purposes only. It is not legal advice. For contracts with significant financial or legal implications, consult a qualified attorney to confirm the exact expiry date and applicable rules.
