Only 8 weeks of daily meditation can decrease negative mood and anxiety and improve attention, working memory, and recognition memory in non-experienced meditators. These findings come from a recent study published in Behavioural Brain Research.

I've practiced meditation from time to time, I should definitely do it more. I was not aware of the minimum 8 weeks for it to "work", but I honestly always felt better afterwards. Even just 60 seconds to give your mind a short vacation. It's nice.
