22-2-110. Computing periods of time.
(a) Except for special elections to fill vacancies for a congressman under W.S. 22-18-105 through 22-18-109, periods of time are computed by excluding the specific day and counting the prescribed number of days, including Saturdays, Sundays and full legal holidays. If the first day of a time period falls on a Saturday, Sunday or full legal holiday, the preceding day which is not a Saturday, Sunday or full legal holiday shall be used. If the last day of a time period falls on a Saturday, Sunday or full legal holiday, the next day which is not a Saturday, Sunday or full legal holiday shall be used. All days, except the specific day, but including the last day, shall be used to compute the time limits established under W.S. 22-18-105 through 22-18-109 unless the last day of a time period falls on a Saturday, Sunday or full legal holiday in which case the next day which is not a Saturday, Sunday or full legal holiday shall be used.
(b) When used to compute periods of time:
(i) "Not later than" is computed by counting the prescribed number of days;
(ii) "Not less than" is computed by counting the prescribed number of days and adding one (1) additional day to the computed time.
