Twitter volume dropped at sunset through Ramadhan

Twitter has blogged that tweets over Ramadhan dropped sharply after sunset in predominantly Muslim countries, rebounding shortly afterwards. 

This is likely due to people going offline to spend time breaking fast with their families, the company said in a blog post in late July. Several countries also saw tweet volume peak about an hour before sunrise, including Saudi Arabia and Malaysia. 

Tweet volumes went up near the time for suhoor*, the pre-dawn meal‎ before fasting begins for the day, and the fajr (dawn) prayer which occurs after suhoor.

*Suhoor can be eaten anytime till slightly before the call to prayer for the fajr prayer. People may also sleep later during Ramadhan as the mealtimes must occur between sunset and fajr.
