作为程序员，没有合适的工具，就得手搓一个，PC端，移动端均可适用。废话不多说，直接上代码。
HTML:
<div class="container"><div class="calculator"><label for="last-period">上次月经开始日期:</label> <input id="last-period" type="date"> <label for="cycle-length">月经周期（天数）:</label> <input id="cycle-length" type="number" placeholder="输入您的月经周期天数"><button onclick="calculateOvulation()">计算</button><div class="result align-center"><div class="align-center">计算结果</div><div id="ovulation-period"></div><div id="safe-period-before"></div><div id="safe-period-after"></div><div id="menstrual-period"></div><div id="explanation"></div></div></div></div>
JS:
function calculateOvulation() { const lastPeriodDate = new Date(document.getElementById('last-period').value); const cycleLength = parseInt(document.getElementById('cycle-length').value); if (!lastPeriodDate || isNaN(cycleLength)) { document.getElementById('explanation').textContent = "请输入有效的日期和周期长度。"; return; } // 计算排卵日（下次月经前14天） const ovulationDate = new Date(lastPeriodDate); ovulationDate.setDate(lastPeriodDate.getDate() + cycleLength - 14); // 计算安全期和月经期 const safePeriodBeforeStart = new Date(lastPeriodDate); const safePeriodBeforeEnd = new Date(ovulationDate); safePeriodBeforeEnd.setDate(ovulationDate.getDate() - 19); const safePeriodAfterStart = new Date(ovulationDate); safePeriodAfterStart.setDate(ovulationDate.getDate() + 1); const safePeriodAfterEnd = new Date(lastPeriodDate); safePeriodAfterEnd.setDate(lastPeriodDate.getDate() + cycleLength - 1); const menstrualPeriodStart = new Date(lastPeriodDate); const menstrualPeriodEnd = new Date(lastPeriodDate); menstrualPeriodEnd.setDate(lastPeriodDate.getDate() + 4); const options = { year: 'numeric', month: 'long', day: 'numeric', weekday: 'long' }; document.getElementById('ovulation-period').textContent = `排卵期: ${ovulationDate.toLocaleDateString('zh-CN', options)}。`; document.getElementById('safe-period-before').textContent = `排卵前安全期: ${safePeriodBeforeStart.toLocaleDateString('zh-CN', options)} - ${safePeriodBeforeEnd.toLocaleDateString('zh-CN', options)}。`; document.getElementById('safe-period-after').textContent = `排卵后安全期: ${safePeriodAfterStart.toLocaleDateString('zh-CN', options)} - ${safePeriodAfterEnd.toLocaleDateString('zh-CN', options)}。`; document.getElementById('menstrual-period').textContent = `月经期: ${menstrualPeriodStart.toLocaleDateString('zh-CN', options)} - ${menstrualPeriodEnd.toLocaleDateString('zh-CN', options)}。`; document.getElementById('explanation').textContent = "排卵期一般在下次月经来潮前的14天左右，" + "排卵前安全期是从上次月经结束到排卵日前5天，" + "排卵后安全期是从排卵日到下次月经开始。"; }
CSS:
