Section 218.6 - Computation of time periods(a)Computation. All time periods are computed using calendar days, including Saturdays, Sundays, and Federal holidays. However, when the time period expires on a Saturday, Sunday, or Federal holiday, the time is extended to the end of the next Federal working day as stated in the legal notice (11:59 p.m. in the time zone of the receiving office for objections filed by electronic means such as email or facsimile).(b)Starting date. The day after publication of the legal notice required by § 218.7(c) is the first day of the objection-filing period.(c)Publication date. The publication date of the legal notice of the EA or final EIS in the newspaper of record or, when the Chief is the responsible official, the FEDERAL REGISTER, is the exclusive means for calculating the time to file an objection. Objectors may not rely on dates or timeframe information provided by any other source.(d)Extensions. Time extensions are not permitted except as provided at paragraph (a) of this section, and § 218.26(b) .
