excel - VBA - Change date language

Question

I'm trying to solve such problem: In macro, that I'm using, one of the parts is to retrieve date month (in full naming), currently is used :

LastMonth = Format(DateSerial(Year(Date), Month(Date) - 1, 1), "mmmm")

But then one problem appears - for persons, who use different regional language settings, date appears in it's local language, but I need to have it for everyone in English.

I was looking around the internet, but haven't found any similar solutions. Does anyone knows, how can this be solved?

Answer 1

Excel formula TEXT allows defining output language, so one of the options is to use it's VBA equivalent:

LastMonth = WorksheetFunction.Text(Date - Day(Date), "[$-409]mmmm")
