(a) If the deadline for submitting an expedited recount petition falls on a Saturday, Sunday, or legal state holiday, the deadline is extended to 10 a.m. of the next regular business day.
(b) Except as provided by Subsection (a), a deadline prescribed by this subchapter is not affected by its falling on a Saturday, Sunday, or holiday.
(c) If the deadline for submitting an application for including remaining paper ballot precincts or an amendment to a petition or application falls on a Saturday, Sunday, or legal state holiday, the recount coordinator shall be accessible or have an agent accessible at the coordinator's office for at least one hour immediately preceding the deadline unless the document subject to the deadline has already been submitted. Failure of the coordinator to comply with this subsection excuses performance until 9 a.m. of the next day that is not a Saturday, Sunday, or legal state holiday.
