Additional info

• Tasks 0.14.5
• Locale: English (UK)
  The task appears briefly then disappears as well from the Day view. Changing the locale to some other beginning Sunday (English US, for instance) produces the appearance of the task on the Week view, but not on the Day view. But this reproduces the aforementioned behavior on week view with tasks due Sunday...
• List view and Month view produce the expected output.
• Similar to issue 3252
• This happened too in previous versions of the Calendar app.

Reproduce the issue in Week and Day views using a task due on Monday, checking both Firefox and Chromium with the English UK locale. Compare the behavior with List and Month views and verify that the task remains visible on its corresponding day in both affected views without changing locale.
