WORD ORIGIN

According to the Barnhardt Concise Dictionary of Etymology, heyday is an alteration of heyda (1526), an exclamation of playfulness or surprise, which is similar to the modern English hurrah. The modern sense of "a period of popularity or success" was first recorded in 1751 and altered the spelling from "da" to "day."

The phrase "in his heyday" (or her as the case may be), appears quite often in print. The immediate implication is that a person was once successful and popular, but is now "past his (or her) prime." Hollywood stars, sports heroes, famous politicians and popular musicians all have their heyday. Afterwards, some quietly fade into the background, while others try to re-live their heyday through the "comeback."

Someone once said "old rockers never die, they just keep getting richer." A quick look at the concert calendar of any major city proves how true this is. Elton John is still selling out huge arenas and Rolling Stones front man Mick Jagger and guitarist Keith Richards are still touring the world.

Folk/rock icon Bob Dylan is 77 years old. At his age, most people are in full retirement. Instead, His "Never Ending Tour" which started in 1988 is still going strong. For fans in Germany the 2019 dates are 31 March - Düsseldorf, 02 April - Würzburg, 04 April - Berlin, 05 April - Magdeburg.
