how to remove the dates from BLOG

I would like to remove all dates from my Blog, not only on my posts
but the whole blog
My content is dateless and plus i can only update at times, not often enough so i don′t want to show this
I will also remove the archives obviously as i don′t want any dates to show (published, edited, created, etc)
how to do this please, let me know asap
here is the website

I am using Tempera Free
I have looked into modifying CSS or some plugins even though i don′t know much about it….
any solutions welcome thanks
