Overview

This section establishes a uniform definition for the term "day" within FAR Subpart 15.5 by cross-referencing the definition provided in FAR 33.101.

Key Rules

  • Calendar Day Basis: Per the referenced FAR 33.101, a "day" is defined as a calendar day, unless otherwise specified.
  • Calculation of Deadlines: If the last day of a designated period falls on a Saturday, Sunday, or legal holiday, the period is extended to the next day that is not a Saturday, Sunday, or legal holiday.
  • Consistency: This ensures that timelines for notifications, debriefings, and protests are calculated using a standardized method across different parts of the FAR.

Practical Implications

  • Contracting Officers and offerors must use calendar days—not business days—when calculating strict deadlines for requesting or providing debriefings.
  • Failure to account for the "calendar day" rule can lead to missed windows for filing timely protests or securing enhanced debriefing rights.
