Changed first day of week...but doesn´t work

[AnD010]

Hi!,
I will try to change first day to week, but something is wrong.
For example, today in Europe is Sunday 11 February, but for me... first day of week is Monday,
don´t Sunday.
I did

            koyomi.weeks = ("Lun", "Mar", "Mie", "Jue", "Vie", "Sab", "Dom")
            koyomi.weeks.0 = "Lun"
            koyomi.weeks.1 = "Mar"
            koyomi.weeks.2 = "Mie"
            koyomi.weeks.3 = "Jue"
            koyomi.weeks.4 = "Vie"
            koyomi.weeks.5 = "Sab"
            koyomi.weeks.6 = "Dom"

But now.. is Monday 11 February in my calendar...this is wrong...today is Sunday 11 February... I can do something for change day of week and re-order days???
Thanks
