做了个狗龄计算器，才发现"1 狗年 = 7 人年"是错的 家里养了只金毛，一直按"狗 1 岁 = 人 7 岁"算，后来查资料发现这个公式根本不科学——狗的第一年其实相当于人的 15 岁左右，而且不同体型的狗衰老速度差很远。 于是做了个工具：dogyearcalc.com ( https://dogyearcalc.com/) 它做了什么： - 内置 4 种计算公式：AKC 体型公式、UC Davis 表观遗传时钟（测 DNA 甲基化得出的）、Standard 方法、以及那个不科学的 Classic 7x 方法（留着做对比） - 支持 386+ 犬种的品种特异性计算，大型犬和小型犬的衰老曲线完全不同 - 多狗对比模式——家里养了两只以上的可以并排看 - 生命阶段可视化 + 当前阶段的健康建议 - 8 种语言（中英日韩德西法葡） 技术方面： 纯静态站，HTML + CSS + 原生 JS ，部署在 Cloudflare Pages 。没有框架，没有注册，加载速度 89ms 。计算全部前端完成，不收集任何数据。 想听听大家的意见： 1.

I rebuilt GreetIGo around that: a small place for coworkers and employees, their important dates, and advance reminders so recognition ha
