文章导读摘要由 Qwen 生成

实现了一个侧边栏日历与倒计时卡片，包含以下核心功能：日历展示:显示当前日期（公历与农历）、星期、生肖、干支年份。动态生成当月日历网格，高亮当天日期。倒计时模块:距离除夕倒计时：实时计算并显示剩余天数（示例中为2026年2月16日）。进度条：分别展示本年、本月、本周的已过去进度（百分比）及剩余天数。农历支持:调用 chinese-lunar.js 库将公历转换为农历，格式化显示为“干支年+生肖年+农历月+农历日”。

注意：本文为早期 Hexo / Butterfly 魔改记录，本站现已迁移到 Astro，相关代码、路径或插件可能已经失效，仅作历史参考。

突然看到某个网站侧边栏有日历和倒计时，就研究了一下，抄下来了（🤭）效果图：

添加js

document.addEventListener("DOMContentLoaded", () => {
    initializeCard();
});

document.addEventListener("pjax:complete", () => {
    initializeCard();
});

function initializeCard() {
    cardTimes();
    cardRefreshTimes();
}

let year, month, week, date, dates, weekStr, monthStr, asideTime, asideDay, asideDayNum, animalYear, ganzhiYear, lunarMon, lunarDay;
const now = new Date();

function cardRefreshTimes() {
    const e = document.getElementById("card-widget-schedule");
    if (e) {
        asideDay = (now - asideTime) / 1e3 / 60 / 60 / 24;
        e.querySelector("#pBar_year").value = asideDay;
        e.querySelector("#p_span_year").innerHTML = (asideDay / 365 * 100).toFixed(1) + "%";
        e.querySelector(".schedule-r0 .schedule-d1 .aside-span2").innerHTML = `还剩<a> ${(365 - asideDay).toFixed(0)} </a>天`;
        e.querySelector("#pBar_month").value = date;
        e.querySelector("#pBar_month").max = dates;
        e.querySelector("#p_span_month").innerHTML = (date / dates * 100).toFixed(1) + "%";
        e.querySelector(".schedule-r1 .schedule-d1 .aside-span2").innerHTML = `还剩<a> ${(dates - date)} </a>天`;
        e.querySelector("#pBar_week").value = week === 0 ? 7 : week;
        e.querySelector("#p_span_week").innerHTML = ((week === 0 ? 7 : week) / 7 * 100).toFixed(1) + "%";
        e.querySelector(".schedule-r2 .schedule-d1 .aside-span2").innerHTML = `还剩<a> ${(7 - (week === 0 ? 7 : week))} </a>天`;
    }
}

function cardTimes() {
    year = now.getFullYear();
    month = now.getMonth();
    week = now.getDay();
    date = now.getDate();

    const e = document.getElementById("card-widget-calendar");

引入

新增+号后面内容

inject:
  head:
  # 自定义css
+    - <link rel="stylesheet" href="/css/calendar.css">

  # 自定义js
+    - <script src="/js/calendar.js"></script>
+    - <script src="https://unpkg.com/chinese-lunar@0.1.4/lib/chinese-lunar.js"></script>

在 blogroot/source/_data 文件夹下创建 widget.yml 文件，并添加以下内容：
