Section 17203 - Computation of Time and Extensions of Time to Respond or Act

(a) In computing the time within which a right may be exercised or an act is to be performed, the first day shall be excluded and the last day shall be included. If the last day is not a Working Day, the time shall be extended to the next Working Day.

(b) Unless otherwise indicated by proof of service, if the envelope was properly addressed, the mailing date shall be presumed to be: a postmark date imprinted on the envelope by the U.S. Postal Service if first-class postage was prepaid; or the date of delivery to a common carrier promising overnight delivery as shown on the carrier's receipt.

(c) Where service of any notice, decision, pleading or other document is by first class mail, and if within a given number of days after such service, a right may be exercised, or an act is to be performed, the time within which such right may be exercised or act performed is extended five days if the place of address is within the State of California, and 10 days if the place of address is outside the State of California but within the United States. However, this Rule shall not extend the time within which the Director may reconsider or modify a decision to correct an error (other than a clerical error) under Labor Code section 1742(b).

(d) Where service of any notice, pleading, or other document is made by an authorized method other than first class mailing, extensions of time to respond or act shall be calculated in the same manner as provided under section 1013 of the Code of Civil Procedure, unless a different requirement has been specified by the appointed Hearing Officer or by another provision of these Rules.
