如何在不超过一个月的可用日期的情况下将7天添加到当前日期？

import datetime

current_date = datetime.datetime.now()
new_date = current_date + datetime.timedelta(days=7)
print(new_date)

const currentDate = new Date();
const newDate = new Date(currentDate.getTime() + 7 * 24 * 60 * 60 * 1000);
console.log(newDate);

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

LocalDate currentDate = LocalDate.now();
LocalDate newDate = currentDate.plus(7, ChronoUnit.DAYS);
System.out.println(newDate);

$currentDate = new DateTime();
$newDate = $currentDate->modify('+7 days');
echo $newDate->format('Y-m-d');
