Question

I have a method that returns the first day of the first week of a month, for making a little calendar:

def month_first_week_day(month, year)
  start = DateTime.civil(year, month, 1)

  start_date = DateTime.commercial(year, cweek, 1)
end

But I have this issue:

Date.civil(2011, 1, 1).cweek # => 52

I want it to return 1, not 52. I found this same problem in java here: Why does the en_GB locale think the 1st of January is the 52nd week of the year?.

Any suggestion?

Answer 1

You could use Date.new(year, month).beginning_of_month instead of writing a function that does the same thing. See more here
As an example

 Date.new(2011, 1).beginning_of_month
 => Sat, 01 Jan 2011
