What is the minimum number of days required to pass a candidate?
According to the Constitution, a daughter Lodge shall not confer a degree on any Brother at less interval than four weeks from his receiving the previous degree. This means that there must be a minimum of 28 days (4 weeks) between the degrees conferred on a candidate.
Additionally, the interval for advancing to a higher degree can be reduced to one week, but only if authorized by a dispensation granted by the Regional Grand Master.
For reference, see Rule 147: "No daughter Lodge shall confer a degree on any Brother at less interval than four weeks from his receiving the previous degree."
