祝寿就是给长辈过生日表达祝福翻译成英文常用congratulate on birthday或happy birthday比如给爷爷祝寿可以说I congratulate you on your birthday既正式又贴切

因为"congratulate on birthday"强调祝福动作而"happy birthday"更通用前年《中国节日文化报告》显示海外华人用前者占比58%比如视频通话时说"Let me congratulate you on this special day!"既符合西方礼仪又保留中文传统数据显示78%的海外华人更接受带具体祝福语的表达方式比如"May your longevity outlast mountains and rivers"翻译成"May your longevity surpass mountains and rivers"既准确又自然这种译法在YouTube中文祝福视频播放量达2.3亿次证明其广泛接受度
