Computing and Extending Time
(a) Computing Time. In computing any period of time prescribed or allowed by these rules the day of the act, event, or default from which the designated period of time begins to run will not be included. Thereafter, every day will be counted including holidays, Saturdays, and Sundays. The last day of the period so computed will be included, unless it is a Saturday, a Sunday, or a legal holiday, in which event the period runs until the end of the next day which is not a Saturday, a Sunday, or a legal holiday.
(b) ‘‘Legal Holiday’’ Defined. As used in these rules, ‘‘legal holiday’’ includes the first day of January, observed as New Year’s Day; the third Monday in January, observed as Martin Luther King Day; the third Monday in February, observed as Washington- Lincoln Day; the last Monday in May, observed as Memorial Day; the nineteenth day of June, observed as Juneteenth Day; the fourth day of July, observed as Independence Day; the first Monday in September, observed as Labor Day; the first Monday in October, observed as Frances Cabrini Day; the 11th day of November, observed as Veteran’s Day; the fourth Thursday in November, observed as Thanksgiving Day; the twenty-fifth day of December, observed as Christmas Day, and any other day except Saturday or Sunday when the court is closed.
(c) Extending Time. For good cause shown, the appellate court may upon motion extend the time prescribed by these rules or by its order for doing any act, or may permit an act to be done after that time expires; but the court may not extend the time to file:
(1) a notice of appeal beyond that prescribed in C.A.R. 4(a); or
(2) a petition to enjoin, set aside, suspend, modify, enforce, or otherwise review, or a notice of appeal from, an order of an administrative agency, board, commission, or officer of the State of Colorado, except as specifically authorized by law.
