Given this short paragraph about the life of George K. McGunnegle, how old was he when he retired and what month of the year did that happen?

Context:
As a member of the 3rd Infantry Regiment and 17th Infantry Regiment, McGunnegle served in the Philippines during the Philippine–American War. After receiving promotion to colonel in 1906, he commanded the 1st Infantry Regiment during service in Washington, the Philippines, and Hawaii. In 1914, he was assigned to command the recruit depot at Fort McDowell, California. He served until recaching the mandatory retirement age of 64 in June 1918. Because World War I was ongoing, McGunnegle agreed to defer retirement and remained on duty at Fort McDowell. The war ended in November 1918, and he remained in command of Fort McDowell to muster out troops as the army demobilized. He retired in July 1919.<|im_end|>
