How long can a Brother serve as Master of the same Lodge?

A Brother may be re-elected to occupy the Eastern Chair as Master of a Lodge for a second successive year, as an article on the Grand Lodge of India's website notes.

Historically, the duration of service depended on local lodge regulations and election schedules. In early nineteenth-century India, for instance, lodges operating under British constitutions held elections on a semi-annual basis, allowing a Master to be re-elected for consecutive six-month terms, or to be called back to the Chair later in the year to complete an unexpired term if his successor departed early 1.
