Dashboard calendar - March is the new February?

Problem reported by Kim Cowlishaw 8 years ago

This morning I have been going through the dashboard calendar to add task reminders and make sure the automatic ones are in the correct place and I have discovered that with effect from 2017 it would appear as though February no longer exists and that we are having 2 months called March. I have scrolled through and this appears to be the case in the next few years as well.

Please can this be corrected - a basic requirement to have a calendar with the correct months and dates on it!
