# Designated Hours > the hours of TIME to TIME on DAY to DAY (inclusive) of every week (except bank and public holidays) or such other hours or days as the Licensor in its **Term:** Designated Hours **Last updated:** 2026-07-29 ## Definition ## What Designated Hours Means in a Contract Designated Hours is a defined term that pins down exactly when a service, facility, licence, or support function is available under an agreement. Rather than leaving availability vague, the contract states specific times of day and specific days of the week during which the obligation applies. This creates a clear, enforceable boundary so both parties know precisely what falls inside and outside the scope of the commitment. The term is most often used where one party, commonly a licensor or service provider, promises access, support, or performance during a set window. Anything requested or occurring outside those hours may fall outside the provider's contractual duty, unless another clause extends coverage or imposes emergency obligations. This makes Designated Hours a load-bearing definition even though it looks like a small piece of boilerplate. ## How Designated Hours Is Defined or Measured Typically, Designated Hours is measured by reference to a start time and end time on a range of days, for example from a morning hour to an evening hour, Monday to Friday inclusive, with bank and public holidays carved out. The exclusion of holidays matters because it prevents disputes about whether a provider was obliged to perform on a day when most businesses are closed. Many versions of this clause also build in flexibility. The definition may allow the party responsible for setting the hours, often the licensor, to change them at its discretion, provided the decision is reasonable and provided notice, commonly four weeks, is given to the other party. This notice period is the practical safeguard: it stops one side from unilaterally and suddenly narrowing availability in a way that disrupts the other party's operations or customer commitments. - A fixed start and end time each day the obligation applies. - A defined range of days, usually excluding weekends unless stated otherwise. - An express carve-out for bank and public holidays. - A mechanism allowing variation, subject to a reasonableness standard and advance notice. ## Where Designated Hours Appears in Agreements The concept shows up wherever continuous or unrestricted access is neither practical nor intended. It is common in software licensing and technology support agreements, where a licensor promises help desk coverage or system availability only during stated business hours, tying into related
