The presentation is made at the annual SFWA Nebula Awards banquet, commonly during May, but it is not one of the Nebulas—which recognize the preceding calendar year's best works of SF and fantasy, selected by vote of all Association members. SFWA officers and past presidents alone submit Grand Master nominations and the final selection must be approved by a majority of that group. The recipient is announced in advance, commonly during the preceding calendar year, which is the publication year and official award year for the Nebulas.
