BUG: Weekly calendar shows TUESDAY as first day on Sundays (with startDayOfWeek = 1)

Version

tui calendar 2.02 (JS)

Test Environment

Brave browser

Current Behavior

On a SUNDAY (today), the calendar shows TUESDAY as the first column of the weekly calendar, and MONDAY is the last.

Today is Sunday, July 10th. When I change the laptop’s date to July 11 (MONDAY), the weekly calendar shows the expected weekly calendar with first column MONDAY and last column SUNDAY. Settings use “startDayOfWeek” = 1:

    var Calendar = window.tui.Calendar;
      var cal = new Calendar('#app', {
        defaultView: 'week',
        isReadOnly: true,
        useDetailPopup: true,
        timezone: { zones: [ { timezoneName: 'Europe/Amsterdam' } ] },
        week: {
          showNowIndicator: false,
          startDayOfWeek: 1,
          hourStart: 8,
          taskView: false,
          narrowWeekend: true,
        },
      });

Expected Behavior

On SUNDAY (today, or any day of the week), I expect the first column of the weekly calendar to be MONDAY and SUNDAY the last.

@victorvogelpoel Yeah, I got it. It’s definitely not related to the timezone.

So the startDayOfWeek option is broken When the current time is on Sunday.

I’ll investigate the issue and try to fix it. Thanks for the report.

And can you reproduce if you set your computer’s date to July 10th (yesterday Sunday)? I think it will show TUESDAY as the first column then.

The bug was apparent yesterday, Sunday. Then I set my laptop’s date to Monday July 11th, and the week calendar showed Mondays as the first column, as expected.
