The better question perhaps is the time for a man to complete the three lessons of Masonry. The lessons are called degrees, each of them building on the previous degree.

The Three degrees are Entered Apprentice, Fellow Craft, and Master Mason.

Between each degree some memorizing of the previous degree is required, and shown to the lodge as proof of knowing that work. That can take a varied amount of time depending on the man’s ability to memorize work. Brother Coaches are called to help with the memory work.

In general terms it would take a year to complete all three lessons including the memory work.

In some jurisdictions around the world, Lodges will only allow one degree per year. Hence it would take about 3 years to complete the degrees.
