الأعلى لهذا اليوم - كل اللغات

as in "todays top list"

I would need some context to be 100% sure tho, but this goes in at least 98% of cases :) If I find context i'll change it.

in Arabic interaces we add top "what".. so if its Top Viewed, it would be = الأكثر مشاهدة لهذا اليوم

top depending on the meaning will be translated differently. I translated it as "most important" Contact me if the meaning is different (as i.e. the most popular today = τα δημοφιλέστερα σήμερα)
