Wrong week number displayed

[ghost]

Hello,

When the prop "showWeekNumbers" is equal to "true", the week numbers displayed are wrong.

For example, for the 12th april 2018, the week number displayed is "14" while we should see "15" (see here).

I made a sandbox with the behavior : https://codesandbox.io/s/xr4ovz55qo

Thanks in advance

I was wondering why it didn't do the same thing in my live example. Finally found out why.

The link also says:
"Week number according to the ISO-8601 standard, weeks starting on Monday". If you do that (firstDayOfWeek={1} ), the week number shows up correctly.

edit: just to point out: I'm not telling you to change the first day of week. It's just an addition to say that US users are affected.

I'm not sure if this has something to do with the firstDayOfTheWeek.

For what I see after a quick debug, this line where we take week[0] (as the first day of the week row) gets the Jan. 1st from the previous year. It should instead get the first day of the week of the current year. This should be easily fixable...

mmm the above seems a different bug 🙄

The fix has been published in v7.1.5. Please report back if you have some feedback, thanks!
