Ramadan
 

If you're planning to travel to the Middle East or North Africa:
There is Ramadan, the month of fasting in muslim countries!
In 2014 it's from June 28th to Jul 27th with 3 days of party (Jul 28th-30th) afterwards.
In 2015 from June 18th - July 16th.
In 2016 from June 06th - July 05th.
During this month, especially in Iran, in rural areas of Turkey or in other islamic countries, you will hardly find restaurants during daytime serving food or drinks - very hard for bikers in summer.
