Labels: pull-request-available (was: )
> [C++] Implement week kernel that accepts DayOfWeekOptions
> ---------------------------------------------------------
>
> Key: ARROW-13561
> URL: https://issues.apache.org/jira/browse/ARROW-13561
> Project: Apache Arrow
> Issue Type: Improvement
> Components: C++
> Reporter: Ian Cook
> Priority: Major
> Labels: pull-request-available
> Time Spent: 10m
> Remaining Estimate: 0h
>
> Arrow has an {{iso_week}} compute kernel that follows the [ISO 8601 week date
> definition|https://en.wikipedia.org/wiki/ISO_week_date#First_week]. Add
> another kernel (maybe named {{week}}) that lets you specify options for how
> exactly to count weeks, like MySQL's week function:
> [https://dev.mysql.com/doc/refman/8.0/en/date-and-time-functions.html#function_week|https://www.google.com/url?q=https://dev.mysql.com/doc/refman/8.0/en/date-and-time-functions.html%23function_week&sa=D&source=editors&ust=1628103672101000&usg=AFQjCNHap0KtiiZ83G_PVRPz5T7z6y-lIQ].
> I think we can reuse the existing {{DayOfWeekOptions}} to specify the
> options, but we should change the description of the {{one_based_numbering}}
> argument to:
> {quote}Number from 1 if true and from 0 if false.
> {quote}
> removing the word "days" from it, so it can control whether days _or_ weeks
> are numbered starting from 0 or 1 depending on where it's used.
