Datejs issue with previous dates

Question

The query last Sunday - 7days returns Wednesday, July 22, 2015 12:00:00 AM (tested on datejs.com). If the issue is unresolvable, can moment.js serve similar queries, especially for dates in the past (the docs do not show equivalents)?

Update: Sugar - this great library solved the problem:

Date.create('this Sunday') // equivalent to "last Sunday"
Date.create('last Monday') // equivalent to "last Sunday - 7days"
Date.create('six days before Sunday') // equivalent to "last Sunday - 7days"

Answer 1

Date.js尚未在8年内更新。它有很多错误。您可以尝试DateJS: Evolved分叉，它已解决了许多分支。

Moment.js目前没有解释类似字符串的功能。
