JavaScript计算获取两个时间戳直接的天数【已验证可正常运行】

js简单小示例

以下代码来自于GPT4o/Claude

function calculateDaysBetweenTimestamps(timestamp1, timestamp2) {const date1 = new Date(timestamp1);const date2 = new Date(timestamp2);// 将日期设置为各自的午夜时间，忽略时分秒date1.setHours(0, 0, 0, 0);date2.setHours(0, 0, 0, 0);// 计算两个日期之间的毫秒差const differenceInTime = date2.getTime() - date1.getTime();// 将毫秒差转换为天数const differenceInDays = Math.round(differenceInTime / (1000 * 3600 * 24));return differenceInDays;
}// 使用示例
const today = Math.floor(Date.now() / 1000); // 当前时间戳（秒）
const futureDate = today + 7 * 24 * 60 * 60; // 7天后的时间戳const daysBetween = calculateDaysBetweenTimestamps(today, futureDate);
console.log(`两个时间戳之间的天数: ${daysBetween}`);
