Section 20170 - Computation of Time Periods

(a) The date of service shall be the day when the matter served is deposited in the mail or with a courier providing overnight delivery, delivered in person, or transmitted electronically pursuant to section 20169.

(b) In computing time periods prescribed by these rules, the date of service as defined in subdivision (a) or other event which starts the time period running is not counted. The last day of the time period is included unless it falls on a Saturday, Sunday or a State or Federal legal holiday as defined in Government Code section 6700, in which case the time period expires on the next business day. Where a time period prescribed is less than seven days, intermediate Saturdays, Sundays, and legal holidays are excluded from the computation.

(c) Whenever a time period begins to run from the time of service of a document on a party and such service is made by mail, five days shall be added to the prescribed period for response. If service is by a courier providing overnight delivery, two business days shall be added to the prescribed period for a response. No days are added to the prescribed period for a response when service is effected personally or electronically.

(d) Documents required to be filed with the Board must be received by the Board by 5:00 p.m. on the last day of the time period unless mailed by registered or certified mail postmarked by that last day, or deposited by the last day with a common carrier promising overnight delivery.
