These dates reflect the earliest date of a composition. In the case of transcriptions or arrangements, it is the original composition date that is listed. In the case of revisions or editions, the earliest edition is listed (for example, Holst's First Suite in E-flat from 1909), unless there was a significant and substantial reworking of the composition, in which case each edition have a separate composition date entry. In the case of medleys of music from multiple years, credit is given to the arranger by listing the arrangement date.
