Screen Name: Period of Performance Start Date
Definition: The date that the parties agree will be the starting date for the contract’s requirements. Usually, this is the same as the date signed but may be different. For example, the period of performance start date may be delayed to avoid major holidays or to coincide with the availability of funds; it may be “post dated” to recognize that the contractor started work before the formal agreement was signed.
