Nonjudicial foreclosure: right to reinstate (cure monetary default) ends five business days before the scheduled sale date

(e) Reinstatement of a monetary default under the terms of an obligation secured by a deed of trust, or mortgage may be made at any time within the period commencing with the date of recordation of the notice of default until five business days prior to the date of sale set forth in the initial recorded notice of sale. ... and, the postponement is for a period that exceeds five business days from the date set forth in the notice of sale, or declared at the time of postponement, then the right of reinstatement is revived as of the date of postponement and shall continue from that date until five business days prior to the date of sale declared at the time of the postponement. Nothing contained herein shall give rise to a right of reinstatement during the period of five business days prior to the date of sale ... As used in this subdivision, the term 'business day' has the same meaning as specified in Section 9.

CCP 12: "The time in which any act provided by law is to be done is computed by excluding the first day, and including the last, unless the last day is a holiday, and then it is also excluded." CCP 12a(a): "If the last day for the performance of any act provided or required by law to be performed within a specified period of time is a holiday, then that period is hereby extended to and including the next day that is not a holiday. For purposes of this section, “holiday” means all day on Saturdays, all holidays specified in Section 135 and, to the extent provided in Section 12b, all days that by terms of Section 12b are required to be considered as holidays." Gov. Code 6707: "When the last day for filing any instrument or other document with a state agency falls upon a Saturday or holiday, such act may be performed upon the next business day with the same effect as if it had been performed upon the day appointed." FRCP 6(a): "The following rules apply in computing any time period specified in these rules, in any local rule or court order, or in any statute that does not specify a method of computing time. (1) ... (A) exclude the day of the event that triggers the period; (B) count every day, including intermediate Saturdays, Sundays, and legal holidays; and (C) include the last day of the period, but if the last day is a Saturday, Sunday, or legal holiday, the period continues to run until the end of the next day that is not a Saturday, Sunday, or legal holiday."
