Month days show incorrect when firstDay is other than Sunday

[olegueret]

In year view, the option firstDay when set to a value other than its default 0 (Sunday), makes the calendar's each day header title show the correct shifted day, but the actual days inside each month are not offset, so they show incorrect. In the other views (month, etc) the day offsets are correct.

When firstDay=0 it works fine: 2015-01-01 is a Thursday as expected:

When firstDay=1 (Monday), 2015-01-01 is transmuted to a Friday!

I think I've found the problem: Now I see there is a related bug #10 in which a comment was made indicating that it seemed to work fine in the frech demo at http://epsy.ldtp.net/fullcalendar/demos/year-french.html

The problem shows up when the lang-all.js is used (indicating the language with the lang parameter) instead of using a specific language with a script in the lang folder, like lang/fr.js

Please, see the attached this pastebin which shows the bug: 2015-01-01 should be a Thursday -jeu-.

Have you found a solution to this? It seems to work on the french demo but I still can't find where the issue is when I implement it in my project

Hi guys... Here I found the issue. Change the file https://github.com/tpruvot/fullcalendar/blob/yearview-v2.2.7/src/year/YearView.js#290

On line 290/291

Replace

dayGrid.start = range.start;
dayGrid.end = range.end;

By

dayGrid.start = range.start.add(view.firstDay, 'days');
dayGrid.end = range.end.add(view.firstDay, 'days');
