Peculiar output coverting Date to Text

I tried to turn =TODAY() into text using the formula below with today's date being 16/12/2015 in cell A2 but got 'January' as the output month. I was expecting 'December'

=DAY(A2)&" "&TEXT(MONTH(A2),"mmmm")&" "&YEAR(A2)

Output = '16 January 2015'

What have I done wrong?

Try

=DAY(A2)&" "&TEXT(A2,"mmmm")&" "&YEAR(A2)


Or really, just
=TEXT(A2,"d mmmm yyyy")

The reason yours was returning January

TEXT(MONTH(A2),"mmmm")

The MONTH function returns a NUMBER from 1-12 based on the month, 1=January, 2=February etc..
So it's currently december so that becomes
TEXT(12,"mmmm")

Dates are really just numbers incrimenting by 1 since January 1 1900.
1 = January 1 1900
12 = January 12 1900
32 = February 1 1900
etc...
42354 = December 16 2015

So 12 is January 12 1900
TEXT(January 12 1900,"mmmm") = "January"

Should read TEXT(A2, "dd mmmm yyyy")

Thanks everyone for your help. Perfectly obvious now and simplest is TEXT("dd mmmm yyyy") which I thought I had tried!

You're welcome.

Are you sure you want "dd...
If it's say December 5th for example it would end up 05 December
But just d.. Would be 5 December
