running days

from Bouvier's Law Dictionary, Revised 6th Ed (1856)
RUNNING DAYS. In settling the lay days, (q.v.) or the days of demurrage, 
(q.v.) the contract sometimes specifies "running days;" by this expression 
is, in general, understood, that the days shall be reckoned like the days in 
a bill of exchange 1 Bell's Comm. 577, 5th ed.
