将出生日期转换为当前年份

import datetime

def convert_birthdate_to_current_year(birthdate):
    current_year = datetime.datetime.now().year
    birth_year = birthdate.year
    age = current_year - birth_year
    return age

# 示例用法
birthdate = datetime.datetime(1990, 5, 15)
age = convert_birthdate_to_current_year(birthdate)
print("年龄：", age)

function convertBirthdateToCurrentYear(birthdate) {
    var currentYear = new Date().getFullYear();
    var birthYear = birthdate.getFullYear();
    var age = currentYear - birthYear;
    return age;
}

// 示例用法
var birthdate = new Date(1990, 4, 15);
var age = convertBirthdateToCurrentYear(birthdate);
console.log("年龄：" + age);

import java.time.LocalDate;
import java.time.Period;

public class Main {
    public static void main(String[] args) {
        LocalDate birthdate = LocalDate.of(1990, 5, 15);
        int age = convertBirthdateToCurrentYear(birthdate);
        System.out.println("年龄：" + age);
    }

    public static int convertBirthdateToCurrentYear(LocalDate birthdate) {
        LocalDate currentDate = LocalDate.now();
        Period period = Period.between(birthdate, currentDate);
        return period.getYears();
    }
}
