La. Civ. Code art. 3454
Current with operative changes from the 2024 Third Special Legislative Session
In computing a prescriptive period, the day that marks the commencement of prescription is not counted. Prescription accrues upon the expiration of the last day of the prescriptive period, and if that day is a legal holiday, prescription accrues upon the expiration of the next day that is not a legal holiday.
