Excel glitch? (Userform Textbox = Format, "Date")

Good day,
I just want to point out a small glitch or am I doing something wrong?
I have the following code that makes my Textbox3 from my Userform add the date format to “YYYY-MM-DD”

I came across yesterday a weird date glitch... When I selected 2013-11-12 it gave me 2013-12-11 but this means December 11, 2013 I want November 12, 2013. Today it works perfect and it writes down the code in accordance to the code, but still doesn’t take the November 12, 2013... Why?
Userform Code:

Note: Plus my Column is set to Custom "YYYY-MM-DD"

Because I have multiple date entries within the same userform, I have multiple calendars set up (total 3), the reason why 3, is that I am able to control multiple date entries to specific textbox without adding dates to multiple textbox... each textboxs is triggered by it's own calendar.

So for this textbox3 I have frmCalendar2.Show that pop-up and I can select my date from this calendar form and on selection it transfers the info to my textbox3.

For the calendar I had some trouble adding multiple entries to different textboxs. If I had for example Textbox3 and textbox4 with date entries... I would add the code:

But it would add the date in both textbox, I know i'm missing something to use only one calendar but that would be another thread

Problem is that if November 12, 2013 is selected it shows as 2013-12-11 but the code sais that the format is YYYY-MM-DD... I need it to show as November 12, 2013 and not December 11, 2013...

But November 13, 2013 works perfect... I am so confused
