Computation of time periods: ambiguous 'from' or 'until' wording generally excludes the first day and includes the last. Computation of prescribed time periods depends on context and purpose to effectuate intention; equivocal phrases like from or until require contextual construction. Where doubt persists, the standard rule treats a period running from one day to another as excluding the first day and including the last, guiding calculation of contractual and statutory time limits.
