如何获取月度中的最后日期

function getLastDateOfMonth(year, month) {
  return new Date(year, month, 0).getDate();
}

console.log(getLastDateOfMonth(2022, 2)); // Output: 28

import calendar

def get_last_date_of_month(year, month):
    return calendar.monthrange(year, month)[1]

print(get_last_date_of_month(2022, 2)) # Output: 28

SELECT LAST_DAY('2022-02-01'); -- Output: 2022-02-28

SELECT DATE_TRUNC('MONTH', '2022-02-01') + INTERVAL '1 MONTH - 1 day'; -- Output: 2022-02-28

const lastDateOfMonth = moment('2022-02-01').endOf('month').date();
console.log(lastDateOfMonth); // Output: 28

from dateutil.relativedelta import relativedelta
from datetime import datetime

last_date_of_month = (datetime(2022, 2, 1) + relativedelta(day=31)).day
print(last_date_of_month) # Output: 28
