Mongo 和 Luxon 中的 weekNumber 之间的差异

Question

我正在对日期进行一些 mongo 聚合，运行遇到了一个有趣的问题，即来自 mongo 的 $week return 不同于weekNumber return来自 Luxon。

在下面的代码片段中，$week 来自 mongo returns 47，而来自 Luxon returns 48.

的 weekNumber

有没有办法将两者归一化，使给定日期 return 与 $week/weekNumber 相同？

我可以从 Luxon 编辑的 return 值中减去一个，但我想了解为什么响应不同，以确定是否有更多 appropriate/elegant 的修复方法这个。

MONGO:

[{
    '$match': {
        'date': {
            '$eq': datetime(2020, 11, 23, 0, 0, 0, tzinfo=timezone.utc)
          }
        }
    }, {
    '$project': {
        'w': {
            '$week': '$date'
        }
    }
}]

LUXON:

import { DateTime } from "luxon";

var week = DateTime.fromJSDate(new Date(2020,10,23)).weekNumber;
console.log(week);

查看文档：

weekNumber:

Week calendar: For ISO week calendar attributes, see the weekYear, weekNumber, and weekday accessors.

$week:

Returns the week of the year for a date as a number between 0 and 53.

Weeks begin on Sundays, and week 1 begins with the first Sunday of the year. Days preceding the first Sunday of the year are in week 0. This behavior is the same as the “%U” operator to the strftime standard library function.

如果您想根据 ISO-8601 获取周数，请使用 $isoWeek():

Returns the week number in ISO 8601 format, ranging from 1 to 53. Week numbers start at 1 with the week (Monday through Sunday) that contains the year’s first Thursday.

在 Luxon 中似乎没有相当于 MongoDB 的 $week
