Dhu al-Qa'dah (Arabic: ذُو ٱلْقَعْدَة, Ḏū al-Qa ʿdah, IPA: [ðu‿l.qaʕ.dah]), also spelled Dhu al-Qi'dah or Zu al-Qa'dah, is the eleventh month in the Islamic calendar.

It could possibly mean "possessor or owner of the sitting and seating place" - the space occupied while sitting or the manner of the sitting, pose or posture.

It is one of the four sacred months in Islam during which warfare is prohibited, hence the name "Master of Truces".

In Ottoman times, the name in Ottoman Turkish was Zi'l-ka'dé,^[1] abbreviation Za.^[2] In modern Turkish, it is Zilkade.
