bug on date displayed on calendar title

[gildonei]

I creted 3 buttons on switch display:

• 1 day
• 3 days
• 5 days

When the users click on the buttons 1 or 5 days, everything works fine, but when the button 3 days is clicked the calendar displays a bigger range date in comparison of the days on the calendar.

Let's supose, today is Feb 2nd. if I press the button 3 days the calendar will display the columns with days 2nd, 3rd and 4th but in the column title will appear 2 Feb 2012 - 6 Feb 2012.

I'm using date Format "d M Y" and I have the following configurations on my calendar

daysToShow : 3,
switchDisplay: {'1 dia': 1, '3 dias': 3, '5 dias': 5},
