Qatar, officially the State of Qatar, is a country in West Asia. It occupies the Qatar Peninsula on the northeastern coast of the Arabian Peninsula in the Middle East; it shares its sole land border with Saudi Arabia to the south, with the rest of its territory surrounded by the Persian Gulf. The Gulf of Bahrain, an inlet of the Persian Gulf, separates Qatar from nearby Bahrain. The capital is Doha, home to over 80% of the country's inhabitants. Most of the land area is made up of flat, low-lying desert.

December 18 is the 352nd day of the year in the Gregorian calendar; 13 days remain until the end of the year.
