It appears that, in my version at least, there is no function that,

Try =TEXT(A1*30;"MMMM").
Please, why the "*30"? It works, but why?
We need to create a date in the appropriate month in order for the
TEXT() function to be able to work on it. And you will know that
dates are stored internally as the number of days after 30 December
1899. If we multiply by 30, 1 maps to 30, i.e. 29 January 1900, 2
maps to 60, i.e. 28 February 1900, and so on up to 12, which gives
360, or 25 December 1900. I fact, we could use 29 or 28 instead: 28
gives dates from 27 January 1900 to 1 December 1900. Anything greater
than 30 spills over into the wrong months after January, and 27
doesn't make it into September properly (or beyond).
It occurs to me now (though I confess it didn't before) that the
correct functioning of this technique might depend on the setting at
Tools | Options... | OpenOffice.org Calc | Calculate | Date. But I
find now that it happens that it works similarly (with multipliers
from 27 to 30) for all three choices of the reference date.

Yes, of course; thank you.
