正在将天数转换为日期时间

from datetime import datetime, timedelta

# 相对天数转换

print(future_date_time)

// 绝对天数转换
const daysSinceEpoch = 738120;
const date = new Date(0); // 1970-01-01T00:00:00Z
date.setDate(date.getDate() + daysSinceEpoch);
console.log(date);

// 相对天数转换
const daysFromNow = 30;
const futureDate = new Date();
futureDate.setDate(futureDate.getDate() + daysFromNow);
console.log(futureDate);

import java.time.LocalDate;

// 绝对天数转换

System.out.println(date);

// 相对天数转换
