如何比较日期部分而不是两个日期的时间？

from datetime import datetime

date1 = datetime(2022, 1, 1)
date2 = datetime(2022, 1, 2)

if date1.date()< date2.date():
    print("date1 is earlier than date2")
else:
    print("date1 is later than date2")

const date1 = new Date(2022, 0, 1);
const date2 = new Date(2022, 0, 2);

if (date1.toDateString()< date2.toDateString()) {
    console.log("date1 is earlier than date2");
} else {
    console.log("date1 is later than date2");
}

import java.time.LocalDate;

LocalDate date1 = LocalDate.of(2022, 1, 1);
LocalDate date2 = LocalDate.of(2022, 1, 2);

if (date1.isBefore(date2)) {
    System.out.println("date1 is earlier than date2");
} else {
    System.out.println("date1 is later than date2");
}
