Twitter has also partnered with @AlArabiya to offer personalised iftar and imsak tweets. Iftar is the time each day when Muslims break the fast, and imsak the time that the fast begins. Twitter users can tweet @AlArabiya with #iftar followed by the name of their city with a hashtag immediately in front (e.g. #Dubai), and the @AlArabiya account will automatically send the time for #iftar or #imsak accordingly.
The same blog post has an interactive map showing where Ramadhan-related tweets occurred.
