The international convention initially played a key role in determining the start date of our fiscal and administrative year.
Rotary's first fiscal year began the day after the first convention ended, on 18 August 1910. The 1911-12 fiscal year also related to the convention, beginning with the first day of the 1911 convention on 21 August.
At its August 1912 meeting, the Board of Directors ordered an audit of the International Association of Rotary Clubs' finances. The auditors recommended that the organization end its fiscal year on 30 June to give the secretary and treasurer time to prepare a financial statement for the convention and board, and determine the proper number of club delegates to the convention.
The executive committee concurred, and at its April 1913 meeting, designated 30 June as the end of the fiscal year. This also allowed for changes to the schedule for reporting club membership and payments. Even The Rotarian changed its volume numbering system to correspond to the fiscal year (beginning with vol. 5, July 1914).
