Week Date appears to be wrong ww (ISO week number, leading zero) is changing on Tuesday
According to Wikipedia
ISO-8601 starts on Monday to Sunday
America start Sunday to Saturday
Islamic start Saturday to Friday
Dopus uses
WW Simple week number, leading zero
ww ISO week number, leading zero
I have used SetAttr META "tags:+{date|ww}" and SetAttr META "tags:+{date|WW}"
Did some testing changing the system clock and got the following
date|WW On Sat 05/11 returns 45 Simple week number, leading zero
date|ww On Sat 05/11 returns 44 ISO week number, leading zero
date|WW On Sun 06/11 returns 45
date|ww On Sun 06/11 returns 44
date|WW On Mon 07/11 returns 45
date|ww On Mon 07/11 returns 44 Should have changed to 45
date|WW On Tue 07/11 returns 45
date|ww On Tue 07/11 returns 45 Changes
date|WW On Wed 07/11 returns 45
date|ww On Wed 07/11 returns 45
date|WW On Thu 07/11 returns 45
date|ww On Thu 07/11 returns 45
date|WW On Fri 07/11 returns 45
date|ww On Fri 07/11 returns 45
date|WW On Sat 07/11 returns 46 Changes
date|ww On Sat 07/11 returns 45
Dopus Manual
Under Codes for date and time
The date codes use the following tokens - note that these tokens are case sensitive! The ISO week and ISO year tokens refer to the ISO (week date system) is a link to en.wikipedia.org/wiki/ISO_week_date
Date Token and Description

In New Year 2016 Seems to Have Broken {Date|YYYY-MM-dd} New Year 2016 Seems to Have Broken {Date|YYYY-MM-dd}
