The guard is changed every hour on the hour October 1 to March 31 in an elaborate ritual. From April 1 through September 30, there are more than double the opportunities to view the change because another change is added on the half hour and the cemetery closing time moves from 5:00 to 7:00 p.m.
During the summer I believe it is every half hour. On the half hour...530 6:00 6:30 etc
It says every hour but I saw two changes in an hour, as well as a short wreath laying ceremony. If you're lucky you can catch something like that.

From April to October every half hour.
Almost every 30 minutes, I guess. Because they changed before I left the place
On the hour I believe
