打字稿时刻日期差异
我在使用时刻来计算天数差异时遇到了几个问题。让我暴露我的问题：
我必须从今天的日期中减去一个日期。例如 2022 年 2 月 28 日至 2022 年 2 月 21 日。以这种方式执行此操作：
const timeDifference = moment("28/02/2022", "DD/MM/YYYY").diff(moment(moment(), "DD/MM/YYYY"), "days");
这将返回 6 天，因为它不包括我相信的最后一天。因为我需要它包含最后一天，所以我执行了以下操作：
const timeDifference = moment("21/02/2022", "DD/MM/YYYY")
.add(1, 'days')
.diff(moment(moment(), "DD/MM/YYYY"), "days");
This now returns 7 days，这正是我所需要的。
现在的问题是我有一个 if 语句，它执行以下操作：
if (timeDifference < 0)
现在，如果 timeDifference 是今天的日期，它会返回 0，但如果它是 20/02/2022，它也会返回 0，因为当我需要它返回-1。
我现在尝试采用不同的方法来执行此操作，
if (moment("20/02/2022") < moment.utc()) {
但是当日期小于今天的日期时，它将进入 if 语句，这不起作用。
Im having several issues using moment to calculate the difference in days. Let me expose my problem:
I have to subtract one date from todays date. For example 28/02/2022 - 21/02/2022. Doing this in this way:
const timeDifference = moment("28/02/2022", "DD/MM/YYYY").diff(moment(moment(), "DD/MM/YYYY"), "days");
This returns 6 days as it doesnt include I believe the last day. Since I need it to include the last day I did the following:
const timeDifference = moment("21/02/2022", "DD/MM/YYYY")
.add(1, 'days')
.diff(moment(moment(), "DD/MM/YYYY"), "days");
This now returns 7 days which is what I need.
Now the problem is that I have an if statement which does the following:
if (timeDifference < 0)
Now if timeDifference is todays date it returns 0 but if its 20/02/2022 it also returns 0 due to the .add when I need it to return -1.
I was now trying to do a different approach to do this if by doing
if (moment("20/02/2022") < moment.utc()) {
but this is not working when the date is less than todays date it will enter the if statement.

我相信您正在寻找的是这样的：
顺便说一句，diff 中不需要双 moment()，ass
diff采用moment实例，无论源如何。I believe what you are looking for is this :
By the way, no need for that double moment() in the diff, ass
difftakesmomentinstance what ever the source.
