## NRO.SEMAJNO

NRO.SEMAJNO kalkulas la numeron de la semajno en la jaro por la interna data valoro kiel difinita en ODF OpenFormula kaj kongrua kun aliaj kalkultabelaj aplikaĵoj.

Supported are two week numbering systems:

System 1: The week containing January 1 is the first week of the year, and is numbered week 1.

System 2: The week containing the first Thursday of the year is the first week of the year, and is numbered week 1. That means that week number 1 of any year is the week that contains January 4th. ISO 8601 defines this system and that the week starts on Monday.
