*N***, formally defined as the difference:**

*[T₁,T₂)***, with the effective starting date**

*T'₂ - T'₁***and ending date**

*T'₁***differing from**

*T'₂***and**

*T₁***in the following occations:**

*T₂*If

**(respectively**

*T₁***) occurs on February and is greater than**

*T₂***, then**

*27***(respectively**

*T'₁***) becomes equal to**

*T'₂***.**

*30*Then

*L = N/360*
