(a) In computing the date upon or by which any act must be done or hearing held by under provisions of this article, the day on which an act or event occurred and from which a designated period of time is to be calculated shall not be included, but the last day in a designated period of time shall be included unless that day falls on a Saturday, Sunday or legal holiday, in which case the next day which is not a Saturday, Sunday or legal holiday shall be considered to be the last day.

(b) Unless the court orders otherwise, if the clerk’s office is inaccessible on the last day for filing, then the time for filing is extended to the first accessible day that is not a Saturday, Sunday or legal holiday.

(c) “Legal holiday” means any day declared a holiday by the president of the United States, the congress of the United States or the legislature of this state, or any day observed by order of the Kansas supreme court. A half holiday is considered as other days and not as a holiday.
