如何检查给定日期是否晚于3天？

要检查给定日期是否晚于3天，你可以使用各种编程语言中的日期和时间库。以下是几种常见编程语言的示例：

Python 示例

from datetime import datetime, timedelta

def is_date_after_three_days(given_date_str):
    given_date = datetime.strptime(given_date_str, '%Y-%m-%d')
    three_days_later = datetime.now() + timedelta(days=3)
    return given_date > three_days_later

# 使用示例
given_date_str = '2023-04-01'
print(is_date_after_three_days(given_date_str))  # 输出结果

JavaScript 示例

function isDateAfterThreeDays(givenDateString) {
    const givenDate = new Date(givenDateString);
    const threeDaysLater = new Date();
    threeDaysLater.setDate(threeDaysLater.getDate() + 3);
    return givenDate > threeDaysLater;
}

// 使用示例
const givenDateString = '2023-04-01';
console.log(isDateAfterThreeDays(givenDateString));  // 输出结果

Java 示例

import java.time.LocalDate;
import java.time.format.DateTimeFormatter;

public class DateChecker {
    public static boolean isDateAfterThreeDays(String givenDateString) {
        LocalDate givenDate = LocalDate.parse(givenDateString, DateTimeFormatter.ISO_LOCAL_DATE);
        LocalDate threeDaysLater = LocalDate.now().plusDays(3);
        return givenDate.isAfter(threeDaysLater);
    }

    public static void main(String[] args) {
        String givenDateString = "2023-04-01";
        System.out.println(isDateAfterThreeDays(givenDateString));  // 输出结果
    }
}
