After 2 days of this post, I found some good stuff in the dark side of PHP... there're some environment variables, that can display the date and weekdays based on the user language and/or configuration.
I'm still writting this class... I hope I finish it soon.
But anyway... thanks for you help. And if you need me for something, you know where you can find me; drop me a message and will be a pleasure to help you.... ah! One day I'll send you a Brazilian girl for you to have fun.... lol
