语域：neutral 常见场景：历史或商业叙述、回顾某人或某事物鼎盛时期 heyday 多用于书面或较正式的回顾性语境，也可在口语中用来指某人或某事物的鼎盛时期；通常不带强烈感情色彩，但要表达‘全盛期’时比较常见于叙事或说明性表达。
与 heyday /ˈheɪdeɪ/ 真正押韵的是 payday /ˈpeɪdeɪ/ 和 mayday /ˈmeɪdeɪ/，它们的重读元音和后续音都相同。day 虽然以 -day 结尾，但单独读 /deɪ/ 且重读，与 heyday 中非重读的 -day 不构成整词押韵。they 的 ey 读 /eɪ/，可帮助记忆 hey 的读音；heady /ˈhɛdi/ 和 heavy /ˈhɛvi/ 形似但发音不同，注意不要混淆。
