Friday is the weekly holiday with many business working only a half day on Thursday. Embassies and government offices are closed on Thursday.
The Muslim holidays of Eid Al-Fitr (at the end of Ramadan), Eid Al-Adha (during the month of the Haj), and the Islamic New Year are all observed in Qatar. The length of the two Eid holidays varies from year to year.
The National Day is on 3 September when embassies and government offices are closed but most private business stays open.
