如何获取两个日历时间之间的差异

from datetime import datetime

# 定义两个日期时间
time1 = datetime(2023, 1, 1, 12, 0, 0)
time2 = datetime(2023, 1, 10, 12, 0, 0)

# 计算差异
difference = time2 - time1

# 输出结果
print(difference.days)  # 输出天数
print(difference.total_seconds())  # 输出总秒数

// 定义两个日期时间
let time1 = new Date('2023-01-01T12:00:00');
let time2 = new Date('2023-01-10T12:00:00');

// 计算差异
let difference = time2 - time1;

// 输出结果（以毫秒为单位）
console.log(difference);  // 输出毫秒数

// 转换为天数
let days = difference / (1000 * 60 * 60 * 24);
console.log(days);  // 输出天数

import java.time.LocalDate;
import java.time.temporal.ChronoUnit;

public class DateTimeDifference {
    public static void main(String[] args) {
        // 定义两个日期
        LocalDate date1 = LocalDate.of(2023, 1, 1);
        LocalDate date2 = LocalDate.of(2023, 1, 10);

        // 计算差异
        long daysBetween = ChronoUnit.DAYS.between(date1, date2);

        // 输出结果
        System.out.println(daysBetween);  // 输出天数
    }
}
