The conquest of Mecca (Arabic: فَتْحُ مَكَّةَFatḥu Makkah, alternatively, "liberation of Mecca") was a military campaign undertaken by Muhammad and his companions during the Muslim–Quraysh War. They led the early Muslims in an advance on the Quraysh-controlled city of Mecca in December 629 or January 630[3][4] (10–20 Ramadan, 8 AH).[3] The fall of the city to Muhammad formally marked the end of the conflict between his followers and the Quraysh tribal confederation.

This is apparently calculated using the tabular Islamic calendar and then substituting Ramadan for Sha'ban in an (ineffective) attempt to allow for intercalation.
