And on the matter of the calendars and holidays, the official calendar used in Qatar and used by individuals alike is the Gregorian calendar ,the change was made in Qatar from the Hijri (lunar) calendar -which was pre-Islamic- to the Gregorian calendar was in the early 80's .

People in Qatar really look at the Hijri calendar during tow moths where religious events happen while most of the other 10 months for some Qatari's are pretty much ignored and unless you read it somewhere you wouldn't know witch day of the lunar month you're on.

Qatar has 3 main holidays with other holidays for other religious groups arranged individually by there workplace which is pretty much flexible since religious freedoms are a constitutional right in Qatar (just like it would be if I worked in the States or Europe).

And the holidays are the Eid alfitr 4-10 days depending if you're in the private sector or government (10 days being the government holiday), Eid aladha 5 days
( but if your going on a pilgrimage you can get a 20 day holiday from work, and that’s a one time exception that you can use and if you want to go again you have to take a personal vacation over the 5 official days) hope it wasn't confusing!!.

And finally the national day on the 3rd of September.
