Calendar Description - Scheme jwn
The Julian Week Number is a count of weeks, just as the Julian Day Number is a count of days. It is based on the first day of the week being a Monday.
The seven day week is thought to have originated in ancient Babylonia around 600 BCE. The day of the week is used with the Julian, Gregorian, Hebrew, Islamic and other calendars.
There are more than one way of numbering the week days. If the scheme only uses text names for the week days, any numbering system can be used since the numbers are not normally visible. However, some calendars put significance on the first day of the week or routinely use the weekday number (i.e. ISO, Hebrew and Islamic calendars) and so the numbering system can be selected depending on how the scheme is specified.
This scheme is based on the week starting on a Monday,
i.e. day 1 = Monday.
It is commonly used with the Julian, Gregorian calendars and variants.
They use the optional field wday.
Because this calendar scheme has limited historical value, its visibility is set at hidden.
Use Case
It is commonly used with the Julian and Gregorian calendars and variants.
They use the optional field wday.
The week field number has some value when considering week differences and ranges. It can also be used with modular arithmetic to create regular weekly intervals.
