# Office Closure > Office Closure means the specified period when an office is not open for business due to a public holiday or other reasons. **Term:** Office Closure **Last updated:** 2026-07-29 ## Definition ## What Office Closure Means in a Contract Office Closure is a contractual concept describing any period during which a business location is not operating under its normal hours.

A multi-site business may need to clarify whether closure of a regional office affects contractual deadlines company-wide or only those tied to that specific site. Time zones can further complicate measurement when parties operate across borders. - Fixed public holiday lists agreed in advance - Discretionary closures announced with notice, such as between Christmas and New Year - Emergency closures triggered by unforeseen events Contracts that rely on service level agreements often exclude Office Closure periods from response time calculations entirely, effectively stopping the clock rather than excusing performance outright. ## Where Office Closure Appears in Agreements Office Closure clauses are common in service contracts, commercial leases, supply agreements, and support or maintenance contracts.
