Based on my recent work with time and date (http://TiddlyTools.com/timer.html), I have learned quite a bit about date nomenclature. In fact, there is a well-defined international standard, ISO-8601 ( https://en.wikipedia.org/wiki/ISO_8601 <https://en.wikipedia.org/wiki/ISO_8601#Ordinal_dates>), that defines how dates are represented and referenced Using that international standard, the "day of year number" is called the *"ordinal date"* (https://en.wikipedia.org/wiki/ISO_8601#Ordinal_dates). Similarly, the standard defines the "week of year" number, which is just referred to as the *"week number"* ( https://en.wikipedia.org/wiki/ISO_week_date). There is also a standard for "*weekday number*" which is *"a digit d from 1 through 7, beginning with Monday and ending with Sunday"* Note that the TWCore date formatting (https://tiddlywiki.com/#DateFormat) that is used by the <<now>> macro already supports "week number" using "WW" and "0WW" formatting codes. It also supports both 4-digit and 2-digit "year number with respect to week number, using "wYYYY" and "wYY" formatting codes respectively. -e -- You received this message because you are subscribed to the Google Groups "TiddlyWiki" group.
