Title: ISO week date Authors: Venue: Wikipedia Year: unknown Canonical: wiki:iso-week-date URL: https://en.wikipedia.org/wiki/ISO_week_date Collector: wikipedia OA: true ABSTRACT The ISO week date system is effectively a leap week calendar system that is part of the ISO 8601 date and time standard issued by the International Organization for Standardization (ISO) since 1988 and, before that, it was defined in ISO (R) 2015 since 1971. It is used (mainly) in government and business for fiscal years, as well as in timekeeping. This was previously known as "Industrial date coding". The system specifies a week year atop the Gregorian calendar by defining a notation for ordinal weeks of the year.
